## Constructor & Destructor Documentation

## ◆ wxSizerXmlHandler()

wxSizerXmlHandler::wxSizerXmlHandler | ( |  | ) |

Constructor.

Initializes the attributes and adds the supported styles.

## Member Function Documentation

## ◆ CanHandle()

virtual bool wxSizerXmlHandler::CanHandle | ( | wxXmlNode * | node | ) |
| virtual

Returns true if the given node can be handled by this class.

If the node concerns a sizer object, the method IsSizerNode is called to know if the class is managed or not. If the node concerns a sizer item or a spacer, true is returned. Otherwise false is returned.

See also
  wxXmlResourceHandler::CanHandle().

Implements wxXmlResourceHandler.

## ◆ DoCreateResource()

virtual wxObject* wxSizerXmlHandler::DoCreateResource | ( |  | ) |
| virtual

Creates a sizer, sizeritem or spacer object, depending on the current handled node.

See also
  wxXmlResourceHandler::DoCreateResource().

Implements wxXmlResourceHandler.

## ◆ DoCreateSizer()

virtual wxSizer* wxSizerXmlHandler::DoCreateSizer | ( | const wxString & | name | ) |
| protectedvirtual

Creates an object of type wxSizer from the XML node content.

This virtual method can be overridden to add support for custom sizer classes to the derived handler.

Notice that if you override this method you would typically overload IsSizerNode() as well.

Example of use of this method:

class MySizerXmlHandler : public wxSizerXmlHandler
{
...
protected:
bool IsSizerNode(wxXmlNode *node) const
{
return IsOfClass(node, "MySizer") ||
wxSizerXmlHandler::IsSizerNode(node));
}
void DoCreateSizer(const wxString& name)
{
if ( name == "MySizer" )
return Handle_MySizer();
else
return wxSizerXmlHandler::DoCreateSizer(name);
}
private:
wxSizer* Handle_MySizer()
{
// Create your own sizer here from XRC content (see
// wxXmlResource methods) and return the instance.
}
};
wxSizer
wxSizer is the abstract base class used for laying out subwindows in a window.
Definition: sizer.h:121
wxSizerXmlHandler
Definition: xh_sizer.h:24
wxSizerXmlHandler::DoCreateSizer
virtual wxSizer * DoCreateSizer(const wxString &name)
Creates an object of type wxSizer from the XML node content.
wxSizerXmlHandler::IsSizerNode
virtual bool IsSizerNode(wxXmlNode *node) const
Used by CanHandle() to know if the given node contains a sizer supported by this class.
wxString
String class for passing textual data to or receiving it from wxWidgets.
Definition: string.h:315
wxXmlNode
Represents a node in an XML document.
Definition: xml.h:74
wxXmlResourceHandler::IsOfClass
bool IsOfClass(wxXmlNode *node, const wxString &classname)
Convenience function.

Since
  2.9.2

## ◆ IsSizerNode()

virtual bool wxSizerXmlHandler::IsSizerNode | ( | wxXmlNode * | node | ) | const
| protectedvirtual

Used by CanHandle() to know if the given node contains a sizer supported by this class.

This method should be overridden to allow this handler to be used for the custom sizer types.

See the example in DoCreateSizer() description for how it can be used.
