Determine wether context menu is shown

[Teis Draiby]

I am using context menus as pull-down menus, activated by buttons. If a
context menu is already open I want the corresponding button to close the
menu instead.
Is there an easy way to determine wether a context menu is 'open'?

regards, Teis

.... and how can I close an open context menu programatically?

Thank you very much, Teis
