hi
how can i disable only a certain treenode in a jtree?
i know that if i use setEnabled(false) on a jtree it would disable
the entire tree, but there's no such method to invoke on a treenode

i dont see why that would solve my problem.
the reason the focusListener dont work on my code is because i use
updateUI() on the combobox when the focusGained method is triggered.
if i'll remove the updateUI() from the listener my code would work fine.
the problem is that i must have the updateUI() where it is now, how can that be done?

hi
how is that the focus listener work only once.
if i use the following code, then when i click on the editable combobox for the first time it will detect the focusGained Event, and it will also detect the focusLost event when i set the combobox out of focus,
but when i click on the combobox for the second time it wont work anymore
why is that?
thanks

Hi
my project's main window is a JFrame, through that window you can open other windows which are modalic JDialog's.
when i go to other apps while my project is runing, and then return to my project's main window(JFrame) through the tasks bar i wouldnt see the active window in my project which is the modalic JDialog, and so i would have to use ALT+TAB to find it,
my question is, how can i avoid it and set the JDialog's i open as always on top of the JFrame ?

thanks
