Hi Tobias,

Yes, the XFrameActionListener is the correct listener. There
is only a 
problem with the order of notification. The layout manager
which 
controls the user interface elements is also
XFrameActionListener. It 
looks like that the layout manager is notified after you get
your 
notification. You can solve the problem using the 
com.sun.star.frame.XLayoutManagerListener. The layout
manager implements 
the interface
com.sun.star.frame.XLayoutManagerEventBroadcaster which 
you have to use to add your listener. You can find the
notifications in 
com.sun.star.frame.LayoutManagerEvents. Use the
UIELEMENT_VISIBLE 
notification and the name of the user interface element: 
"private:resource/menubar/menubar". Whenever you
get 
COMPONENT_REATTACHED you should wait for the
UIELEMENT_VISIBLE 
notification and then you change the menu bar.

Regards,
Carsten

I solved it this way: I registered a XLayoutManagerListener,
as you
adivsed. I do not receive a UIELEMENT_VISIBLE event, but a
LAYOUT_EVENT
(event number 2). When this event is fired, I first check if
the menu
items already exist. If not they are added again.

Thank you for your help!

Greetings, Tobias

P.S.: Thank you for adding support of icons for transient
toolbar items
in OOo 2.3. I really appreciate this feature!
