Hello all!

I think, it will be good idea to add WhenSelected-callback to DropList.

My variant:
DropChoise.h

class DropList ...
...
Callback WhenSelected;
...

DropList.cpp

void DropList::Select() {
	int c = list.GetCursor();
	if(c >= 0)
		value = key[c];
	if(dropfocus)
		SetFocus();
	Sync();
	UpdateAction();
	WhenSelected.Execute();
}

Best regards,
Anton

UpdateAction above calls generic WhenAction (like for almost any other widget when user changes the value of widget). (It also sets modify flag for widget).

Is WhenSelected supposed to be any different?
