      :rtype: `RichTextObjectList`     








   .. method:: GetRangeSize(self, range : RichTextRange, size : Size, descent : int, dc : DC, context : RichTextDrawingContext, flags : int, position: Point=Point(0,0), parentSize: Size=DefaultSize, partialExtents: Optional[List[int]]=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

      :type `flags`: int
      :param `position`: 
      :type `position`: wx.Point

   .. method:: HitTest(self, dc : DC, context : RichTextDrawingContext, pt : Point, flags: int=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`:

         One of the :ref:`wx.richtext.RichTextHitTestFlags`  values.

      :rtype: `bool`








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

      Invalidates the object at the given range. 
                 

      With no argument, invalidates the whole object. 
                 


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




      :rtype: `None`     








   .. 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`

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

   .. method:: Move(self, pt : Point)

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


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




      :rtype: `None`     








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

      Removes and optionally deletes the specified child. 
                 


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