real popup without command bar

[Erwin Ahlers]

Hello,
it seems not to be possible to program a real popup menu without the
usage of a command bar. Is this true?
I would like to create a button and when someone click on it a popup
(like on the right click on items) is shown at the position of the
button. With the command bars I have to create a bar and this is
(normally) always visible and on a fixed position, may be even in the
higher menu area together with the other bars.

Does anyone know if it's possible to make "real popups" and if yes,
give me a hint how to do?

Thanks
Erwin
