Constructor & Destructor Documentation

wxRichTextDrawingHandler::wxRichTextDrawingHandler ( const wxString &  name = wxEmptyString )

inline

Creates a drawing handler object.

Member Function Documentation

wxString wxRichTextDrawingHandler::GetName ( ) const

inline

Returns the name of the handler.

virtual bool wxRichTextDrawingHandler::GetVirtualAttributes ( wxRichTextAttr &  attr, wxRichTextObject *  obj  ) const

pure virtual

Provides virtual attributes that we can provide.

virtual int wxRichTextDrawingHandler::GetVirtualSubobjectAttributes ( wxRichTextObject *  obj, wxArrayInt &  positions, wxRichTextAttrArray &  attributes  ) const

pure virtual

Gets the mixed virtual attributes for individual positions within the object.

For example, individual characters within a text object may require special highlighting. Returns the number of virtual attributes found.

virtual int wxRichTextDrawingHandler::GetVirtualSubobjectAttributesCount ( wxRichTextObject *  obj ) const

pure virtual

Gets the count for mixed virtual attributes for individual positions within the object.

For example, individual characters within a text object may require special highlighting.

virtual bool wxRichTextDrawingHandler::GetVirtualText ( const wxRichTextPlainText *  obj, wxString &  text  ) const

pure virtual

Gets the virtual text for this object.

virtual bool wxRichTextDrawingHandler::HasVirtualAttributes ( wxRichTextObject *  obj ) const

pure virtual

Returns true if this object has virtual attributes that we can provide.

virtual bool wxRichTextDrawingHandler::HasVirtualText ( const wxRichTextPlainText *  obj ) const

pure virtual

Do we have virtual text for this object? Virtual text allows an application to replace characters in an object for editing and display purposes, for example for highlighting special characters.

void wxRichTextDrawingHandler::SetName ( const wxString &  name )

inline

Sets the name of the handler.
