==========================================================================================================================================
|phoenix_title|  **wx.propgrid.PGProperty**
==========================================================================================================================================

:ref:`wx.propgrid.PGProperty`  is base class for all :ref:`wx.propgrid.PropertyGrid`  properties and as such it is not intended to be instantiated directly.          

In sections below we cover few related topics. 



- :ref:`Supplied Ready-to-use Property Classes <wx.propgrid.PGProperty>`   
- :ref:`Creating Custom Properties <wx.propgrid.PGProperty>` 






|phoenix_title| Supplied Ready-to-use Property Classes
======================================================

Here is a list and short description of supplied fully-functional property classes. They are located in either :ref:`props.h`  or :ref:`advprops.h`. 

- :ref:`wx.propgrid.ArrayStringProperty`   
- :ref:`wx.propgrid.BoolProperty`   
- :ref:`wx.propgrid.ColourProperty`   
- :ref:`wx.propgrid.CursorProperty`   
- :ref:`wx.propgrid.DateProperty`   
- :ref:`wx.propgrid.DirProperty`   
- :ref:`wx.propgrid.EditEnumProperty`   
- :ref:`wx.propgrid.EnumProperty`   
- :ref:`wx.propgrid.FileProperty`   
- :ref:`wx.propgrid.FlagsProperty`   
- :ref:`wx.propgrid.FloatProperty`   
- :ref:`wx.propgrid.FontProperty`   
- :ref:`wx.propgrid.ImageFileProperty`   
- :ref:`wx.propgrid.IntProperty`   
- :ref:`wx.propgrid.LongStringProperty`   
- :ref:`wx.propgrid.MultiChoiceProperty`   
- :ref:`wx.propgrid.PropertyCategory`   
- :ref:`wx.propgrid.StringProperty`   
- :ref:`wx.propgrid.SystemColourProperty`   
- :ref:`wx.propgrid.UIntProperty` 




|phoenix_title| PropertyCategory
================================

Not an actual property per se, but a header for a group of properties. Regardless inherits from :ref:`wx.propgrid.PGProperty`, and supports displaying 'labels' for columns other than the first one. Easiest way to set category's label for second column is to call :meth:`wx.propgrid.PGProperty.SetValue`   with string argument.  

|phoenix_title| StringProperty
==============================

Simple string property. Supported special attributes:

- ``PG_STRING_PASSWORD``: Set to ``True`` in order to echo value as asterisks and to use ``TE_PASSWORD``  on the editor (:ref:`wx.TextCtrl`). 
- ``PG_ATTR_AUTOCOMPLETE``: Set to ``True`` to enable auto-completion (use a :ref:`ArrayString`  value), and is also supported by any property that happens to use a TextCtrl-based editor. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  



  .. note:: 

   :ref:`wx.propgrid.StringProperty`  has a special trait: if it has value of "<composed>", and also has child properties, then its displayed value becomes composition of child property values, similar as with :ref:`wx.propgrid.FontProperty`, for instance.  






|phoenix_title| IntProperty
===========================

It derives from :ref:`wx.propgrid.NumericProperty`  and displays value as a signed long integer. :ref:`wx.propgrid.IntProperty`  seamlessly supports 64-bit integers (i.e. :ref:`LongLong`) on overflow. To safely convert variant to integer, use code like this: ::

    # Thanks to the magic of Python nothing extra needs to be done here.

Getting 64-bit value: ::

    def OnButtonClick(self, propGrid, value):
        dlgSize = wx.Size(... size of your dialog ...)
        dlgPos = propGrid.GetGoodEditorDialogPosition(self, dlgSize)

        # Create dialog dlg at dlgPos. Use value as initial string
        # value.
        with MyCustomDialog(None, title, pos=dlgPos, size=dlgSize) as dlg:
            if dlg.ShowModal() == wx.ID_OK:
                value = dlg.GetStringValue()
                return (True, value)
            return (False, value)

Setting 64-bit value: ::

    self.SetFlag(wx.propgrid.PG_PROP_NO_ESCAPE)

Supported special attributes:

- ``PG_ATTR_MIN``, ``PG_ATTR_MAX``  to specify acceptable value range. 
- ``PG_ATTR_SPINCTRL_STEP``, ``PG_ATTR_SPINCTRL_WRAP``, ``PG_ATTR_SPINCTRL_MOTION``: Sets SpinCtrl editor parameters. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| UIntProperty
============================

Like :ref:`wx.propgrid.IntProperty`, but displays value as  int. To set the prefix used globally, manipulate ``PG_UINT_PREFIX``  string attribute. To set the globally used base, manipulate ``PG_UINT_BASE``  int attribute. Regardless of current prefix, understands (hex) values starting with both "0x" and "$" (apart from edit mode). Like :ref:`wx.propgrid.IntProperty`, :ref:`wx.propgrid.UIntProperty`  seamlessly supports 64-bit  integers (i.e. :ref:`ULongLong`). Same :ref:`Variant`  safety rules apply. Supported special attributes:

- ``PG_ATTR_MIN``, ``PG_ATTR_MAX``: Specifies acceptable value range. 
- ``PG_UINT_BASE``: Defines base. Valid constants are ``PG_BASE_OCT``, ``PG_BASE_DEC``, ``PG_BASE_HEX``  and ``PG_BASE_HEXL``  (lowercase characters). Arbitrary bases are **not**  supported. 
- ``PG_UINT_PREFIX``: Defines displayed prefix. Possible values are ``PG_PREFIX_NONE``, :ref:`wx.propgrid.PG_PREFIX_0x`  and ``PG_PREFIX_DOLLAR_SIGN``. Only ``PG_PREFIX_NONE``  works with decimal and octal numbers. 
- ``PG_ATTR_SPINCTRL_STEP``, ``PG_ATTR_SPINCTRL_WRAP``, ``PG_ATTR_SPINCTRL_MOTION``: Sets SpinCtrl editor parameters. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  



  .. note:: 

   For example how to use seamless 64-bit integer support, see :ref:`wx.propgrid.IntProperty`  documentation (just use :ref:`ULongLong`  instead of :ref:`LongLong`).  






|phoenix_title| FloatProperty
=============================

Like :ref:`wx.propgrid.StringProperty`, but converts text to a double-precision floating point. Default float-to-text precision is 6 decimals, but this can be changed by modifying ``PG_FLOAT_PRECISION``  attribute. Note that when displaying the value, sign is omitted if the resulting textual representation is effectively zero (for example, -0.0001 with precision of 3 will become 0.0 instead of -0.0). This behaviour is unlike what C standard library does, but should result in better end-user experience in almost all cases. Supported special attributes:

- ``PG_ATTR_MIN``, ``PG_ATTR_MAX``: Specifies acceptable value range. 
- ``PG_FLOAT_PRECISION``: Sets the (max) precision used when floating point value is rendered as text. The default -1 means shortest floating-point 6-digit representation. 
- ``PG_ATTR_SPINCTRL_STEP``, ``PG_ATTR_SPINCTRL_WRAP``, ``PG_ATTR_SPINCTRL_MOTION``: Sets SpinCtrl editor parameters. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| BoolProperty
============================

Represents a boolean value. :ref:`wx.Choice`  is used as editor control, by the default. ``PG_BOOL_USE_CHECKBOX``  attribute can be set to ``True`` in order to use check box instead. Supported special attributes:

- ``PG_BOOL_USE_CHECKBOX``: If set to ``True`` uses check box editor instead of combo box. 
- ``PG_BOOL_USE_DOUBLE_CLICK_CYCLING``: If set to ``True`` cycles combo box instead showing the list. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| LongStringProperty
==================================

Like :ref:`wx.propgrid.StringProperty`, but has a button that triggers a small text editor dialog. Note that in long string values, some control characters are escaped: tab is represented by "\\t", line break by "\\n", carriage return by "\\r" and backslash character by "\\\\". If another character is preceded by backslash, the backslash is skipped. Note also that depending on the system (port), some sequences of special characters, like e.g. "\\r\\n", can be interpreted and presented in a different way in the editor and therefore such sequences may not be the same before and after the edition. To display a custom dialog on button press, you can subclass :ref:`wx.propgrid.LongStringProperty`  and override DisplayEditorDialog, like this: ::



Also, if you wish not to have line breaks and tabs translated to escape sequences, then do following in constructor of your subclass: ::



Supported special attributes:

- ``PG_DIALOG_TITLE``: Sets a specific title for the text editor dialog. 




|phoenix_title| DirProperty
===========================

Like :ref:`wx.propgrid.LongStringProperty`, but the button triggers dir selector instead. Supported special attributes:

- ``PG_DIALOG_TITLE``: Sets specific title for the dir selector. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| FileProperty
============================

Like :ref:`wx.propgrid.LongStringProperty`, but the button triggers file selector instead. Default wildcard is "All files..." but this can be changed by setting ``PG_FILE_WILDCARD``  attribute. Supported special attributes:

- ``PG_DIALOG_TITLE``: Sets a specific title for the file dialog. 
- ``PG_FILE_DIALOG_STYLE``: Sets a specific :ref:`wx.FileDialog`  style for the file dialog. 
- ``PG_FILE_WILDCARD``: Sets wildcard (see :ref:`wx.FileDialog`  for format details), "All
files..." is default. 
- ``PG_FILE_SHOW_FULL_PATH``: Default ``True``. When ``False``, only the file name is shown (i.e. drive and directory are hidden). 
- ``PG_FILE_SHOW_RELATIVE_PATH``: If set, then the filename is shown relative to the given path string. 
- ``PG_FILE_INITIAL_PATH``: Sets the initial path of where to look for files. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| EnumProperty
============================

Represents a single selection from a list of choices - :ref:`wx.adv.OwnerDrawnComboBox`  is used to edit the value.  

|phoenix_title| FlagsProperty
=============================

Represents a bit set that fits in a long integer. :ref:`wx.propgrid.BoolProperty`  sub- properties are created for editing individual bits. Textctrl is created to manually edit the flags as a text; a continuous sequence of spaces, commas and semicolons are considered as a flag id separator. **Note:**  When changing "choices" (i.e. flag labels) of :ref:`wx.propgrid.FlagsProperty`, you will need to use :meth:`wx.propgrid.PGProperty.SetChoices`   - otherwise they will not get updated properly. :ref:`wx.propgrid.FlagsProperty`  supports the same attributes as :ref:`wx.propgrid.BoolProperty`.  

|phoenix_title| ArrayStringProperty
===================================

Property that manages a list of strings. Allows editing of a list of strings in :ref:`wx.TextCtrl`  and in a separate dialog. Supported special attributes:

- ``PG_ARRAY_DELIMITER``: Sets string delimiter character. 
- ``PG_DIALOG_TITLE``: Sets a specific title for the editor dialog. Default is comma (','). 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| DateProperty
============================

Property representing :ref:`wx.DateTime`. Default editor is DatePickerCtrl, although TextCtrl should work as well. Supported special attributes:

- ``PG_DATE_FORMAT``: Determines displayed date format (with :meth:`wx.DateTime.Format` ). Default is recommended as it is locale-dependent. 
- ``PG_DATE_PICKER_STYLE``: Determines window style used with :ref:`wx.adv.DatePickerCtrl`. Default is ``DP_DEFAULT``  | ``DP_SHOWCENTURY``. Using ``DP_ALLOWNONE``  enables additional support for unspecified property value. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| EditEnumProperty
================================

Represents a string that can be freely edited or selected from list of choices - custom combobox control is used to edit the value.  

|phoenix_title| MultiChoiceProperty
===================================

Allows editing a multiple selection from a list of strings. This is property is pretty much built around concept of :ref:`wx.MultiChoiceDialog`. It uses :ref:`ArrayString`  value. Supported special attributes:

- ``PG_ATTR_MULTICHOICE_USERSTRINGMODE``: If > 0, allows user to manually enter strings that are not in the list of choices. If this value is 1, user strings are preferably placed in front of valid choices. If value is 2, then those strings will placed behind valid choices. 
- ``PG_DIALOG_TITLE``: Sets a specific title for the editor dialog. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| ImageFileProperty
=================================

Property representing image file(name). Like :ref:`wx.propgrid.FileProperty`, but has thumbnail of the image in front of the filename and autogenerates wildcard from available image handlers. Supported special attributes:

- ``PG_DIALOG_TITLE``: Sets a specific title for the file dialog. 
- ``PG_FILE_DIALOG_STYLE``: Sets a specific :ref:`wx.FileDialog`  style for the file dialog. 
- ``PG_FILE_WILDCARD``: Sets wildcard (see :ref:`wx.FileDialog`  for format details), "All
files..." is default. 
- ``PG_FILE_SHOW_FULL_PATH``: Default ``True``. When ``False``, only the file name is shown (i.e. drive and directory are hidden). 
- ``PG_FILE_SHOW_RELATIVE_PATH``: If set, then the filename is shown relative to the given path string. 
- ``PG_FILE_INITIAL_PATH``: Sets the initial path of where to look for files. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| ColourProperty
==============================

**Useful alternate editor:**  Choice. Represents :ref:`wx.Colour`. :ref:`wx.Button`  is used to trigger a colour picker dialog. There are various sub-classing opportunities with this class. See below in :ref:`wx.propgrid.SystemColourProperty`  section for details. Supported special attributes:

- ``PG_COLOUR_HAS_ALPHA``: If set to ``True`` allows user to edit the alpha colour component. 

  .. seealso:: :ref:`PropertyGrid Property Attribute Identifiers <propertygrid property attribute identifiers>`  






|phoenix_title| FontProperty
============================

Represents :ref:`wx.Font`. Various sub-properties are used to edit individual subvalues. Supported special attributes:

- ``PG_DIALOG_TITLE``: Sets a specific title for the font dialog. 




|phoenix_title| SystemColourProperty
====================================

Represents :ref:`wx.Colour`  and a system colour index. :ref:`wx.Choice`  is used to edit the value. Drop-down list has color images. Note that value type is :ref:`wx.propgrid.ColourPropertyValue`  instead of :ref:`wx.Colour`  (which :ref:`wx.propgrid.ColourProperty`  uses). ::

    class MyProperty(wx.propgrid.PGProperty):
        # All arguments of this ctor should have a default value -
        # use wx.propgrid.PG_LABEL for label and name
        def __init__(self,
                     label = wx.propgrid.PG_LABEL,
                     name = wx.propgrid.PG_LABEL,
                     value = ""):
            wx.propgrid.PGProperty.__init__(label, name)
            self.value = value

        def DoGetEditorClass(self):
            # Determines editor used by property.
            # You can replace 'TextCtrl' below with any of these
            # builtin-in property editor identifiers: Choice, ComboBox,
            # TextCtrlAndButton, ChoiceAndButton, CheckBox, SpinCtrl,
            # DatePickerCtrl.
            return wx.PGEditor_TextCtrl

        def ValueToString(self, value, argFlags):
            # TODO: Convert given property value to a string and return it
            return ""

        def StringToValue(self, text, argFlags):
            # TODO: Adapt string to property value and return it
            value = do_something(text)
            return (True, value)

In :ref:`wx.propgrid.SystemColourProperty`, and its derived class :ref:`wx.propgrid.ColourProperty`, there are various sub-classing features. To set a basic list of colour names, call :meth:`wx.propgrid.PGProperty.SetChoices` . ::





|phoenix_title| CursorProperty
==============================

Represents a :ref:`wx.Cursor`. :ref:`wx.Choice`  is used to edit the value. Drop-down list has cursor images under some (wxMSW) platforms.   



|phoenix_title| Creating Custom Properties
==========================================

New properties can be created by subclassing :ref:`wx.propgrid.PGProperty`  or one of the provided property classes, and (re)implementing necessary member functions. Below, each virtual member function has ample documentation about its purpose and any odd details which to keep in mind. Here is a very simple 'template' code: ::

    import wx.propgrid as wxpg

    class MyProperty(wxpg.PGProperty):

        def __init__(self, label=wxpg.PG_LABEL, name=wxpg.PG_LABEL, value=0):
            wxpg.PGProperty.__init__(self, label, name)
            self.my_value = int(value)

        def DoGetEditorClass(self):
            """
            Determines what editor should be used for this property type. This
            is one way to specify one of the stock editors.
            """
            return wxpg.PropertyGridInterface.GetEditorByName("TextCtrl")

        def ValueToString(self, value, flags):
            """
            Convert the given property value to a string.
            """
            return str(value)

        def StringToValue(self, st, flags):
            """
            Convert a string to the correct type for the property.

            If failed, return False or (False, None). If success, return tuple
            (True, newValue).
            """
            try:
                val = int(st)
                return (True, val)
            except (ValueError, TypeError):
                pass
            except:
                raise
            return (False, None)

Since :ref:`wx.propgrid.PGProperty`  derives from :ref:`wx.Object`, you can use standard ``DECLARE_DYNAMIC_CLASS`` and ``IMPLEMENT_DYNAMIC_CLASS`` macros. From the above example they were omitted for sake of simplicity, and besides, they are only really needed if you need to use ``RTTI`` with your property class. You can change the 'value type' of a property by simply assigning different type of variant with SetValue.  **It is mandatory to implement** :ref:`VariantData` **class for all data types used as property values.**   You can use macros declared in :ref:`wx.propgrid.PropertyGrid`  headers. For instance: ::

    # NOTE: wxVariants are handled internally in wxPython. Conversions are
    # implicitly done for those types that wxVariant already knows about, and
    # the Raw PyObject is used for those that it doesn't know about.





.. note:: 

   Uses int value, similar to :ref:`wx.propgrid.EnumProperty`, unless text entered by user is is not in choices (in which case string value is used).

   **Possible constructors**::

       PGProperty()
       
       PGProperty(label, name)
       
   
   PGProperty is base class for all PropertyGrid properties and as
   such it is not intended to be instantiated directly.



   .. method:: AdaptListToValue(self, list, value)

      Adapts list variant into proper value using consecutive :meth:`ChildChanged`   calls.                  


      :param `list`: 
      :type `list`: PGVariant
      :param `value`: 
      :type `value`: PGVariant







   .. method:: AddChoice(self, label, value=PG_INVALID_VALUE)

      Append a new choice to property's list of choices.                  




      :param `label`: Label for added choice.  
      :type `label`: string

   .. method:: AddPrivateChild(self, prop)

      Adds a private child property.                  

      If you use this instead of :meth:`wx.propgrid.PropertyGridInterface.Insert`   or :meth:`wx.propgrid.PropertyGridInterface.AppendIn` , then property's parental type will automatically be set up to ``PG_PROP_AGGREGATE``. In other words, all properties of this property will become private.                  


      :param `prop`: 
      :type `prop`: wx.propgrid.PGProperty







   .. method:: AppendChild(self, childProperty)

      Use this member function to add independent (i.e.                  

      regular) children to a property. 

                


      :param `childProperty`: 
      :type `childProperty`: wx.propgrid.PGProperty




      :rtype: :ref:`wx.propgrid.PGProperty`







      :returns: 

         Appended childProperty.  







      .. note::

      Determines, recursively, if all children are not unspecified.                  




      :param `pendingList`: Assumes members in this :ref:`Variant`  list as pending replacement values.   
      :type `pendingList`: PGVariant






      :rtype: `bool`



                  





   .. method:: AreChildrenComponents(self)

      Returns ``True`` if children of this property are component values (for instance, points size, face name, and is_underlined are component values of a font).                  

      :rtype: `bool`








   .. method:: ChangeFlag(self, flag, set)

      Sets or clears given property flag.                  

      Mainly for internal use. 

                


      :param `flag`: 
      :type `flag`: wx.propgrid.PGPropertyFlags
      :param `set`: 
      :type `set`: bool






      .. note:: 

         Setting a property flag never has any side-effect, and is intended almost exclusively for internal use. So, for example, if you want to disable a property, call ::

          Enable(False)

         instead of setting ``PG_PROP_DISABLED``  flag.  







      .. seealso:: :meth:`HasFlag` , GetFlags()   








   .. method:: ChildChanged(self, thisValue, childIndex, childValue)

      Called after value of a child property has been altered.                  

      Must return new value of the whole property (after any alterations warranted by child's new value). 

      Note that this function is usually called at the time that value of this property, or given child property, is still pending for change, and as such, result of :meth:`GetValue`   or m_value should not be relied on. 

      Sample pseudo-code implementation: 

      ::

          # TBW






      :param `thisValue`: Value of this property. Changed value should be returned (in previous versions of :ref:`wx.propgrid.PropertyGrid`  it was only necessary to write value back to this argument).   
      :type `thisValue`: PGVariant
      :param `childIndex`: Index of child changed (you can use Item(childIndex) to get child property).   
      :type `childIndex`: int
      :param `childValue`: (Pending) value of the child property.  
      :type `childValue`: PGVariant










      :rtype: :ref:`PGVariant`



                  



      :returns: 

         Modified value of the whole property.   








   .. method:: DeleteChildren(self)

      Deletes children of the property.                   





   .. method:: DeleteChoice(self, index)

      Removes entry from property's :ref:`wx.propgrid.PGChoices`  and editor control (if it is active).                  

      If selected item is deleted, then the value is set to unspecified.                  


      :param `index`: 
      :type `index`: int







   .. method:: DoGetAttribute(self, name)

      Returns value of an attribute.                  

      Override if custom handling of attributes is needed. 

      Default implementation simply return ``None`` variant.                  


      :param `name`: 
      :type `name`: string




      :rtype: :ref:`PGVariant`








   .. method:: DoGetEditorClass(self)

      Returns pointer to an instance of used editor.                  

      :rtype: :ref:`wx.propgrid.PGEditor`








   .. method:: DoGetValidator(self)

      Returns pointer to the :ref:`wx.Validator`  that should be used with the editor of this property (``None`` for no validator).                  

      Setting validator explicitly via SetPropertyValidator will override this. 

      In most situations, code like this should work well (macros are used to maintain one actual validator instance, so on the second call the function exits within the first macro): 

      ::

          class MyPropertyClass(wx.propgrid.PGProperty):
              ...
              def DoGetValidator(self):
                  validator = MyValidator(...)

                  ... prepare validator...

                  return validator



                

      :rtype: :ref:`Validator`







      .. note:: 

         You can get common filename validator by returning :meth:`wx.propgrid.FileProperty.GetClassValidator` . :ref:`wx.propgrid.DirProperty`, for example, uses it.   








   .. method:: DoGetValue(self)

      Override this to return something else than m_value as the value.                  

      :rtype: :ref:`PGVariant`








   .. method:: DoSetAttribute(self, name, value)

      Reimplement this member function to add special handling for attributes of this property.                  

                


      :param `name`: 
      :type `name`: string
      :param `value`: 
      :type `value`: PGVariant




      :rtype: `bool`







      :returns: 

         Return ``False`` to have the attribute automatically stored in m_attributes. Default implementation simply does that and nothing else.  







      .. note:: 

         To actually set property attribute values from the application, use :meth:`wx.propgrid.PGProperty.SetAttribute`   instead.   








   .. method:: Enable(self, enable=True)

      Enables or disables the property.                  

      Disabled property usually appears as having grey text. 




      :param `enable`: If ``False``, property is disabled instead.  
      :type `enable`: bool

   .. method:: InsertChoice(self, label, index, value=PG_INVALID_VALUE)

      Inserts a new choice to property's list of choices.                  




      :param `label`: Text for new choice  
      :type `label`: string
      :param `index`: Insertion position. Use ``wx.NOT_FOUND`` to append.  
      :type `index`: int
      :param `value`: Value for new choice. Do not specify if you wish this to equal choice index.   
      :type `value`: int










      :rtype: `int`



                  





   .. method:: IntToValue(self, number, argFlags=0)

      Converts integer (possibly a choice selection) into :ref:`Variant`  value appropriate for this property.                  




      :param `number`: Integer to be translated into variant.   
      :type `number`: int
      :param `argFlags`: If ``PG_FULL_VALUE``  is set, returns complete, storable value instead of displayable one.  
      :type `argFlags`: int










      :rtype: `tuple`



                  



      :returns: 

         ( `bool`, `variant` ) 







      .. note:: 

   

         - If property is not supposed to use choice or spinctrl or other editor with int-based value, it is not necessary to implement this method. 
         - Default implementation simply assign given int to m_value. 
         - If property uses choice control, and displays a dialog on some choice items, then it is preferred to display that dialog in IntToValue instead of OnEvent. 
         - You might want to take into account that m_value is Mull variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).  











   .. method:: IsCategory(self)

      Returns ``True`` if this property is actually a :ref:`wx.propgrid.PropertyCategory`.                  

      :rtype: `bool`








   .. method:: IsEnabled(self)

      Returns ``True`` if property is enabled.                  

      :rtype: `bool`








   .. method:: IsExpanded(self)

      Returns ``True`` if property has visible children.                  

      :rtype: `bool`








   .. method:: IsRoot(self)

      Returns ``True`` if this property is actually a RootProperty.                  

      :rtype: `bool`








   .. method:: IsSomeParent(self, candidateParent)

      Returns ``True`` if candidateParent is some parent of this property.                  

      Use, for example, to detect if item is inside collapsed section.                  


      :param `candidateParent`: 
      :type `candidateParent`: wx.propgrid.PGProperty




      :rtype: `bool`








   .. method:: IsSubProperty(self)

      Returns ``True`` if this is a sub-property.                  

      :rtype: `bool`








   .. method:: IsTextEditable(self)

      Returns ``True`` if property has editable :ref:`wx.TextCtrl`  when selected.                  

                

      :rtype: `bool`







      .. note:: 

         Although disabled properties do not displayed editor, they still return ``True`` here as being disabled is considered a temporary condition (unlike being read-only or having limited editing enabled).   








   .. method:: IsValueUnspecified(self)

      Returns ``True`` if property's value is considered unspecified.                  

      This usually means that value is Null variant.                  

      :rtype: `bool`








   .. method:: IsVisible(self)

      Returns ``True`` if all parents expanded.

   .. method:: Item(self, i)

      Returns child property at index `i`.

      :rtype: :ref:`wx.propgrid.PGProperty`








   .. method:: Last(self)

      Returns last sub-property.                  

      :rtype: :ref:`wx.propgrid.PGProperty`








   .. method:: OnCustomPaint(self, dc, rect, paintdata)

      Override to paint an image in front of the property value text or drop-down list item (but only if :meth:`wx.propgrid.PGProperty.OnMeasureImage`   is overridden as well).                  

      If property's :meth:`OnMeasureImage`   returns size that has height != 0 but less than row height ( < 0 has special meanings), :ref:`wx.propgrid.PropertyGrid`  calls this method to draw a custom image in a limited area in front of the editor control or value text/graphics, and if control has drop-down list, then the image is drawn there as well (even in the case :meth:`OnMeasureImage`   returned higher height than row height). 

      ``NOTE``: Following applies when :meth:`OnMeasureImage`   returns a "flexible" height ( using  ``PG_FLEXIBLE_SIZE(W,H)``   macro), which implies variable height items: If (rect.x+rect.width) is < 0, then this is a measure item call, which means that dc is invalid and only thing that should be done is to set paintdata.m_drawnHeight to the height of the image of item at index paintdata.m_choiceItem. This call may be done even as often as once every drop-down popup show. 




      :param `dc`: :ref:`wx.DC`  to paint on.   
      :type `dc`: wx.DC
      :param `rect`: Box reserved for custom graphics. Includes surrounding rectangle, if any. If x+width is < 0, then this is a measure item call (see above).   
      :type `rect`: wx.Rect
      :param `paintdata`: :ref:`wx.propgrid.PGPaintData`  structure with much useful data about painted item. ::




      :type `paintdata`: wx.propgrid.PGPaintData








                  



      .. note:: 

   

         - You can actually exceed rect width, but if you do so then paintdata.m_drawnWidth must be set to the full width drawn in pixels. 
         - Due to technical reasons, rect's height will be default even if custom height was reported during measure call. 
         - Brush is guaranteed to be default background colour. It has been already used to clear the background of area being painted. It can be modified. 
         - Pen is guaranteed to be 1-wide 'black' (or whatever is the proper colour) pen for drawing framing rectangle. It can be changed as well. 










      .. seealso:: :meth:`ValueToString`     








   .. method:: OnEvent(self, propgrid, wnd_primary, event)

      Events received by editor widgets are processed here.                  

      Note that editor class usually processes most events. Some, such as button press events of TextCtrlAndButton class, can be handled here. Also, if custom handling for regular events is desired, then that can also be done (for example, :ref:`wx.propgrid.SystemColourProperty`  custom handles  ``wxEVT_CHOICE``   to display colour picker dialog when 'custom' selection is made). 

      If the event causes value to be changed, :meth:`SetValueInEvent`   should be called to set the new value. 

      The parameter `event`  is the associated :ref:`wx.Event`. 




      :param `propgrid`: 
      :type `propgrid`: wx.propgrid.PropertyGrid
      :param `wnd_primary`: 
      :type `wnd_primary`: wx.Window
      :param `event`: 
      :type `event`: wx.Event




      return ``True`` if any changes in value should be reported. 



      :rtype: `bool`



                  



      .. note:: 

   

         - If property uses choice control, and displays a dialog on some choice items, then it is preferred to display that dialog in IntToValue instead of OnEvent.  











   .. method:: OnMeasureImage(self, item=-1)

      Returns size of the custom painted image in front of property.                  

      This method must be overridden to return non-default value if OnCustomPaint is to be called. 




      :param `item`: Normally -1, but can be an index to the property's list of items.  
      :type `item`: int






      :rtype: :ref:`Size`



                  



      .. note:: 

   

         - Default behaviour is to return :ref:`wx.Size`, which means no image. 
         - Default image width or height is indicated with dimension -1. 
         - You can also return ``PG_DEFAULT_IMAGE_SIZE``  which equals DefaultSize.  











   .. method:: OnSetValue(self)

      This virtual function is called after m_value has been set.                  

                 



      .. note:: 

   

         - If m_value was set to Null variant (i.e. unspecified value), :meth:`OnSetValue`   will not be called. 
         - m_value may be of any variant type. Typically properties internally support only one variant type, and as such :meth:`OnSetValue`   provides a good opportunity to convert supported values into internal type. 
         - Default implementation does nothing.  











   .. method:: OnValidationFailure(self, pendingValue)

      Called whenever validation has failed with given pending value.                  

                


      :param `pendingValue`: 
      :type `pendingValue`: PGVariant






      .. note:: 

         If you implement this in your custom property class, please remember to call the base implementation as well, since they may use it to revert property into pre-change state.   








   .. method:: RecreateEditor(self)

      If property's editor is created this forces its recreation.                  

      Useful in SetAttribute etc. Returns ``True`` if actually did anything.                  

      :rtype: `bool`








   .. method:: RefreshChildren(self)

      Refresh values of child properties.                  

      Automatically called after value is set.                   





   .. method:: RefreshEditor(self)

      If property's editor is active, then update it's value.                   





   .. method:: SetAttribute(self, name, value)

      Sets an attribute for this property.

      :type `name`: string
      :param `value`: Value of attribute.  
      :type `value`: PGVariant






                  



      .. note:: 

         Setting attribute's value to Null variant will simply remove it from property's set of attributes.   








   .. method:: SetAttributes(self, attributes)

      Set the property's attributes from a Python dictionary.



   .. method:: SetAutoUnspecified(self, enable=True)

      Set if user can change the property's value to unspecified by modifying the value of the editor control (usually by clearing it).                  

      Currently, this can work with following properties: :ref:`wx.propgrid.IntProperty`, :ref:`wx.propgrid.UIntProperty`, :ref:`wx.propgrid.FloatProperty`, :ref:`wx.propgrid.EditEnumProperty`. 




      :param `enable`: Whether to enable or disable this behaviour (it is disabled by default).

   .. method:: SetBackgroundColour(self, colour, flags=PG_RECURSE)

      Sets property's background colour.                  




      :param `colour`: Background colour to use.  
      :type `colour`: wx.Colour
      :param `flags`: Default is ``PG_RECURSE``  which causes colour to be set recursively. Omit this flag to only set colour for the property in question and not any of its children.  
      :type `flags`: int






                  



      .. note:: 

         Unlike :meth:`wx.propgrid.PropertyGridInterface.SetPropertyBackgroundColour` , this does not automatically update the display.

      Sets selected choice and changes property value.                  

      Tries to retain value type, although currently if it is not string, then it is forced to integer.                  


      :param `newValue`: 
      :type `newValue`: int

   .. method:: SetValueFromInt(self, value, flags=0)

      Converts integer to a value, and if successful, calls :meth:`SetValue`   on it.                  

      Default behaviour is to do nothing. 




      :param `value`: Int to get the value from.

      Call this function in :meth:`OnEvent` , OnButtonClick() etc.                  

      to change the property value based on user input. 

                


      :param `value`: 
      :type `value`: PGVariant






      .. note:: 

         This method is  since it doesn't actually modify value, but posts given variant as pending value, stored in :ref:`wx.propgrid.PropertyGrid`.   








   .. method:: SetValueToUnspecified(self)

      Sets property's value to unspecified (i.e.                  

      Null variant).                   





   .. method:: SetWasModified(self, set=True)

      Call with ``False`` in :meth:`OnSetValue`   to cancel value changes after all (i.e.                  

      cancel ``True`` returned by :meth:`StringToValue`   or :meth:`IntToValue` ).                  


      :param `set`: 
      :type `set`: bool







   .. method:: StringToValue(self, text, argFlags=0)

      Converts text into :ref:`Variant`  value appropriate for this property.                  




      :param `text`: Text to be translated into variant.  
      :type `text`: string
      :param `argFlags`: If ``PG_FULL_VALUE``  is set, returns complete, storable value instead of displayable one (they may be different). If ``PG_COMPOSITE_FRAGMENT``  is set, text is interpreted as a part of composite property string value (as generated by :meth:`ValueToString`   called with this same flag).  
      :type `argFlags`: int










      :rtype: `tuple`




      You might want to take into account that m_value is Null variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).                    



      :returns: 

         ( `bool`, `variant` ) 







      .. note:: 

         Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.  








   .. method:: UpdateParentValues(self)

      Updates composed values of parent non-category properties, recursively.                  

      Returns topmost property updated. 

                

      :rtype: :ref:`wx.propgrid.PGProperty`







      .. note:: 

         Must not call :meth:`SetValue`   (as can be called in it).   








   .. method:: UsesAutoUnspecified(self)

      Returns ``True`` if containing grid uses ``PG_EX_AUTO_UNSPECIFIED_VALUES``.                  

      :rtype: `bool`








   .. method:: ValidateValue(self, value, validationInfo)

      Implement this function in derived class to check the value.                  

      Return ``True`` if it is ok. Returning ``False`` prevents property change events from occurring. 

                


      :param `value`: 
      :type `value`: PGVariant
      :param `validationInfo`: 
      :type `validationInfo`: wx.propgrid.PGValidationInfo




      :rtype: `bool`







      .. note:: 

   

         - Default implementation always returns ``True``.  











   .. method:: ValueToString(self, value, argFlags=0)

      Converts property value into a text representation.                  




      :param `value`: Value to be converted.   
      :type `value`: PGVariant
      :param `argFlags`: If 0 (default value), then displayed string is returned. If ``PG_FULL_VALUE``  is set, returns complete, storable string value instead of displayable. If ``PG_EDITABLE_VALUE``  is set, returns string value that must be editable in textctrl. If ``PG_COMPOSITE_FRAGMENT``  is set, returns text that is appropriate to display as a part of string property's composite text representation.  
      :type `argFlags`: int








      :rtype: `string`



                  



      .. note:: 

         Default implementation calls :meth:`GenerateComposedValue` .
