I have an application with a menu bar. depending on which menu item you select, a different applet will be displayed in the same internal frame. This is all working fine
my problem is now i want to remove the "X" button from the internal frame and add code so that when you select a menu item it checks first to see if another applet is currently open in the internal frame. if it is i need to close the internal frame without using the "X" button before opening the new applet so:
How do i check to see if an internal frame or applet are currently open?
how do i close the internal frame without the close button
