Reimplemented in wxRichTextTable, and wxRichTextParagraphLayoutBox.

virtual int wxRichTextCompositeObject::HitTest ( wxDC dc,

const wxPoint pt,
long &  textPosition,
wxRichTextObject **  obj,
wxRichTextObject **  contextObj,
int  flags = 0 
)
virtual

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).

Returns
One of the wxRichTextHitTestFlags values.

Reimplemented from wxRichTextObject.

Reimplemented in wxRichTextTable, wxRichTextCell, wxRichTextBuffer, wxRichTextParagraph, and wxRichTextParagraphLayoutBox.

Invalidates the object at the given range.

With no argument, invalidates the whole object.

Reimplemented from wxRichTextObject.

Reimplemented in wxRichTextParagraphLayoutBox.

virtual bool wxRichTextCompositeObject::IsAtomic ( ) const
virtual

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.
