         ( `bool`, `pt`, `height` ) 








   .. method:: GetChild(self, n)

      Returns the nth child.                  


      :param `n`: 
      :type `n`: int




      :rtype: :ref:`wx.richtext.RichTextObject`








   .. method:: GetChildAtPosition(self, pos)

      Returns the child object at the given character position.

      :rtype: `int`








   .. method:: GetChildren(self)

      Returns the children.                  

      :rtype: :ref:`RichTextObjectList`








   .. method:: GetRangeSize(self, range, size, descent, dc, context, flags, position=Point(0,0), parentSize=DefaultSize, partialExtents=None)

      Returns the object size for the given range.                  

      Returns ``False`` if the range is invalid for this object.                  


      :param `range`: 
      :type `range`: wx.richtext.RichTextRange
      :param `size`: 
      :type `size`: wx.Size
      :param `descent`:

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

      :param `flags`: 
      :type `flags`: int

   .. method:: HitTest(self, dc, context, pt, flags=0)

      Hit-testing: returns a flag indicating hit test details, plus information about position.                  

      `contextObj`  is returned to specify what object position is relevant to, since otherwise there's an ambiguity. @ obj might not be a child of `contextObj`, since we may be referring to the container itself if we have no hit on a child - for example if we click outside an object. 

      The function puts the position in `textPosition`  if one is found. `pt`  is in logical units (a zero y position is at the beginning of the buffer). 

                


      :param `dc`: 
      :type `dc`: wx.DC
      :param `context`: 
      :type `context`: wx.richtext.RichTextDrawingContext
      :param `pt`: 
      :type `pt`: wx.Point
      :param `flags`:

      :rtype: `bool`








   .. method:: Invalidate(self, invalidRange=RICHTEXT_ALL)

      Invalidates the object at the given range.                  

      With no argument, invalidates the whole object.                  


      :param `invalidRange`: 
      :type `invalidRange`: wx.richtext.RichTextRange







   .. method:: IsAtomic(self)

      Returns ``True`` if no user editing can be done inside the object.                  

      This returns ``True`` for simple objects, ``False`` for most composite objects, but ``True`` for fields, which if composite, should not be user-edited.                  

      :rtype: `bool`








   .. method:: IsComposite(self)

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

      :rtype: `bool`

      Returns ``True`` if the buffer is empty.                  

      :rtype: `bool`

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


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







   .. method:: RemoveChild(self, child, deleteChild=False)

      Removes and optionally deletes the specified child.                  


      :param `child`: 
      :type `child`: wx.richtext.RichTextObject
      :param `deleteChild`: 
      :type `deleteChild`: bool
