I have not tested it yet, but are the other events available, like double
click on any button?

I think it would be "nice" to display the current values, ie. the values
presently in force at the time any dialog is displayed; for example, from
the right click menu on a canvas Range displays a dialog with four edit
boxes for x1, y1, x2, y2. Those boxes are displayed empty (as it's true for
most fields on most dialogs (some display default values))... I'm suggesting
that the current values (in this example, the current range values for the
canvas) are displayed to the user for editing. Even in this simple case
there is the benefit of letting the user know what the current setting are
(a starting place to assist in what the values could be in order to make the
canvas smaller/larger, whatever user's need is). In other cases displaying
current values would also save some typing, for example in TCutG::Fit
dialog.

Something akin to the dialog in the TCanvas Range right click menu.
