Hello,
I have a menu in my application which offers several connection options
after doing a network lookup. The menu is currently build triggered by a
JMenuLister. The lookup is typically slow and the menu will
open with a noticable delay.
I wanted to use the same method I use in the trees,
* first display a string "Updating .." and start the query in another
thread
* remove the updating JMenuItem and replace by the real ones.
This does work, but the opened menu (or better its JPopup) is not
redrawn properly. Though I remove the updating item and add new
ones in the AWT Event Thread, all new items are squezed together in the
space of the former updating item :-(
I experimented using something like menu.getPopup().validate
but the opened menu is not drawn correct.
Any tips appreciated, Carsten
