Ring control height / comman button with pop up menu

[MaWie]

Hi,

1.) is there any way to change the height of a ((popup)menu) ring control without changing the text size?

Any hidden attribute?

What I want to have is big button with a small size font that opens a drop-down (or popup) menu in order to choose a value.

Using a big-size control would be nice, because I also want to have this small arrow at the right side, to show that this "button" holds a drop-down menu.

Please find enclosed an example, how it might look like.

2.) In order to find a solution, i have tried to place a popup menu ring right beside a command button, but failed to open the popup menu programmatically when clicking the button (using a button callback). CallCtrlCallback with EVENT_KEYPRESS(Space)/EVENT_LEFT_CLICK/EVENT_COMMIT on the ring control doesn't seem to work. How to call/show the popup menu programatically?

As you have already discovered, the only ring control for which you can set the height is the popup menu.

You don't need anything to interactovely opne the menu in a popup menu ring control: simply click on it.

On the other hand, it is possible to programmatically open popup menu by using FakeKeyStroke as in the attached example. Note that even if I can open the menu from within the originating button callback, nevertheless I prefered to post a deferred callback to obtain this so that the button callback can terminate before the menu is opened and handled by its native callback.
