XCOMP triggering an OK event

[Bastiaan Olij]

Hey Michael,

I really wish that TigerLogic would document these things much better.
All I'm trying to do is create an alternative looking push button but
one that support OK button and Cancel Button button modes.

Thanks (and to others who also reacted), I will try out a few of these
options :)

Cheers,

Bas

Normally, these in-build events go through specific routes that create internal default behaviour events/actions. There is no way of accessing/triggering those if sending the event alone does not do it.

If your xcomp does not implement a window control your only option may be to use evalCalculation(), unless you can get hold of the windows HWND ($framehwnd) so you can do a direct call to the windows $event method by calling ECOsendEvent( window’s $framehwnd, ….)
