Hi , I have a problem with a 3rd party library. by the way. please help,
Applet contain Panel name "Chooser"
"Chooser" contain a button "open"
After click on the "open" button it will invoke Jpopupmenu
JpopupMnu have another panel inside
Some people overridden setVisible() method
I seem that when i click on any area on anything this panel on Jpopupmenu Jpopupmanu will be diappear.
someone HINT that :
have to do something with the popup's overriden setVisible method. Tell the "Chooser" from applet that the application is an applet, so it doesn't set the "popup" window non-visible.
