Hi guys (not meant in chauvinistic fashion),

I got something like a "dynamic JPopupMenu" (i call it dynamic because it changes its size depending on the size of a Jlist). My problem is that, the JList it gets its data from is empty in the beginning, thus the Jpopupmenu is not displayed (or just a small fraction of it), when right clicking. Is there a EASY way to set the "inital size".
Please it should be EASY and not super-tricky.
Thanks

Edit1:
myJPopupMenu.setSize(100,100) doesn't work

I'm not sure I understand you correctly. Do you want to display an empty popup menu, so that the user knows his right-click (or whatever action that brings up the popup menu) has been processed? If this is the case, I'd put a single disabled menu item onto the popup menu with text like "no action available" or something similar.

Actually, yes I've done something similar:
the right click checks the "data JList" first, if its empty no JPopupMenu is opened, else it shows the JPopupMenu with all contents.
 
It is sorta covered in the JavaRanch Style Guide.
