/** \class TDialogCanvas
\ingroup gpad
 
A canvas specialized to set attributes.
 
It contains, in general, TGroupButton objects.
When the APPLY button is executed, the actions corresponding
to the active buttons are executed via the Interpreter.
 
See examples in TAttLineCanvas, TAttFillCanvas, TAttTextCanvas, TAttMarkerCanvas
