      Returns ``True`` if this object is composite.                  

      :rtype: `bool`

      Returns ``True`` if this class of object is floatable.                  

      :rtype: `bool`

      :rtype: `bool`








   .. method:: IsShown(self)

      Returns ``True`` if the object will be shown, ``False`` otherwise.                  

      :rtype: `bool`








   .. method:: IsTopLevel(self)

      Returns ``True`` if this object is top-level, i.e. contains its own paragraphs, such as a text box.                  

      :rtype: `bool`








   .. method:: Layout(self, dc, context, rect, parentRect, style)

      Lay the item out at the specified position with the given size constraint.                  

      Layout must set the cached size. `rect`  is the available space for the object, and `parentRect`  is the container that is used to determine a relative size or position (for example if a text box must be 50% of the parent text box).                  


      :param `dc`: 
      :type `dc`: wx.DC

      :rtype: `bool`








   .. method:: LayoutToBestSize(self, dc, context, buffer, parentAttr, attr, availableParentSpace, availableContainerSpace, style)

      Lays out the object first with a given amount of space, and then if no width was specified in attr, lays out the object again using the minimum size.                  

      `availableParentSpace`  is the maximum space for the object, whereas `availableContainerSpace`  is the container with which relative positions and sizes should be computed. For example, a text box whose space has already been constrained in a previous layout pass to `availableParentSpace`, but should have a width of 50% of `availableContainerSpace`. (If these two rects were the same, a 2nd pass could see the object getting too small.)

   .. method:: Merge(self, object, context)

      Returns ``True`` if this object merged itself with the given one.                  

      The calling code will then delete the given object.                  


      :param `object`: 
      :type `object`: wx.richtext.RichTextObject
      :param `context`: 
      :type `context`: wx.richtext.RichTextDrawingContext




      :rtype: `bool`








   .. method:: Move(self, pt)

      Moves the object recursively, by adding the offset from old to new.                  


      :param `pt`: 
      :type `pt`: wx.Point







   .. method:: Reference(self)

   .. method:: SetMaxSize(self, sz)

      Sets the maximum object size as calculated by Layout.                  

      This allows us to fit an object to its contents or allocate extra space if required.                  


      :param `sz`: 
      :type `sz`: wx.Size







   .. method:: SetMinSize(self, sz)

      Sets the minimum object size as calculated by Layout.                  

      This allows us to constrain an object to its absolute minimum size if necessary.                  


      :param `sz`: 
      :type `sz`: wx.Size







   .. method:: SetName(self, name)
