Hi,

I've been asked to do things "while the left mouse button on an icon of a menu toolbar is being hold down" and when it's being released.

I've tried to add pbm_lbuttondown and pbm_lbuttonup, but that doesn't seem to be fired.

So my question is: Should I maybe use a different event or is it simply not possible with a menuitem?

TIA

How can I apply UI Theme to runtime application?

Hi Miguel;

   The Menu Object and the Menu Item object is very much encapsulated and basically, only triggers either a SELECTED or CLICKED event due to the way it internally handles events. All the actual Menu events are fired  against the Window and then re-directed by the PBVM.

Regards ... Chris

Thank you Chris, I was afraid of that, maybe I'll see what possibilities I'd have using the new ribbon menu, though that might be even more restricted.

Greetings, Miguel - 

In the cases when I wasn't sure what messages were sent to a particular control, I've created a DataWindow to hold Windows Message ID's, WParam and LParam values, created a DataStore, then coded the Other event to simply record a log of the events not handled by PB for subsequent, off-line analysis. I've never used this technique with Menu objects, so I cannot say with certainty this would work in your case...but, it's an idea to consider.

HTH, John

Thank you, yes I thought of that also. Later I'll try to see if I can add an "other" event to a menu and see if it works. I'm not too sure, since if you look at "selected" or "clicked" events of a menu, there's no pbm_..... tied to it, which makes me think that the menu object is going to be an exception.

But I'll try later on.

Cheers

I tried adding an other event (pbm_other) to a menu item, but it never was fired. Oftentimes PowerBuilder lets programmers play outside the normal sandbox, but with menus, not so much.
