Hi,
I have certain menu/toolbar commands that I wish to hide (on both menus and toolbars) when they are disabled. What would be the best method for this?
I know I can call SetVisible() explicitly, but it would be much better if this could be handled in the update handlers.
Any suggestions? Thanks!

Hi,
Update handler called only for controls - not for toolbars. you can catch idle message and call SetVisible in this handler.

Hi Oleg,
I'm not sure I understand you, surely update handlers are called for toolbar buttons? Or do you mean they aren't called for controls in the toolbar?
This fits with a similar problem that I have. I have a combobox in a toolbar and I want to disable it using an update handler (as I do for the normal buttons on the bar), but it doesn't seem to get called. :(
I also have some comboboxes in a drop down menu (from a toolbar button), but the handler IS called for them! Why the difference, or am I doing something wrong?
Thanks.

I believe you have called this somewhere in your code:
pControl->SetFlags(xtpFlagManualUpdate);
In that case, uncomment it and it will work as expected.

DOH!
You're quite right, I had set that flag (that's what happens when you copy and paste!) and removing it fixed the problem!
 Well 'spotted', and thanks!
