如何在Java Swing中使用[Esc]键最小化JInternalFrame？

Question

I used InputMap and ActionMap to binding Esc to closing window, by using setVisible(false) . How can I create [Esc] Hotkey to minimize the window in java swing?

Answer 1

Instead of using

frame.setVisible( false );

You would use:

frame.setExtendedState(JFrame.ICONIFIED);

You should also check out Dialog Escape Key for a more complete implementation that will handle the Escape key. For example the code will allow closing of popup windows (on a combo box) to close before attempting to close the dialog. The code was written for a dialog and would need to be modified slightly for a JFrame.
