Yeah, it's not something I've tried before, so I'm not sure how feasible it is to make it look good, but hopefully it's a starting point. Adding a proper context menu option to the API would be better :)

[quote="trixmoto"]I don't think you can have a popup menu, but you could have a "Menu" link that you click and this shows another panel with links, each one you click on would close the panel. This would look similar to a menu, if done right, but would be all left clicks. Does that make sense?[/quote]
Indeed this makes sense, to simulate a popup with a panel. Some difference remains resp. are coding-work to avoid it:
Open the panel near the mouseclick and avoid that the panel opens out of the sceen and a panel closes not if I click out of the panel.
I will make some experiments...
Thank you for the tip.

I want to create a new popup menu in my own form/panel, triggered by a button click or a right mouse-click. Is it possible ?
For example I search a simple and quick way to switch of the a panel caption, similar in the CD-Cover panel "Show Title bar".
A popup menu would reduce the need of a lot of buttons.
