//*-*   A DialogCanvas is 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
