Iconifying and Maximizing a JFrame</h3>
This example implements methods to iconify, deiconify, minimize, and
maximize a frame. In general, you should not make calls such as
<code>JFrame.setExtendedState(Frame.ICONIFIED)</code> since this would destroy
the maximized state of the frame. Instead, the Frame.ICONIFIED state
should be combined with the current maximized state of the frame.
<pre>
// This method iconifies a frame; the maximized bits are not affected.
public void iconify(JFrame frame) {
int state = frame.getExtendedState();
// Set the iconified bit
state |= Frame.ICONIFIED;
// Iconify the frame
frame.setExtendedState(state);
}
// This method deiconifies a frame; the maximized bits are not affected.
public void deiconify(JFrame frame) {
int state = frame.getExtendedState();
// Clear the iconified bit
state &= ~Frame.ICONIFIED;
// Deiconify the frame
frame.setExtendedState(state);
}
// This method minimizes a frame; the iconified bit is not affected
public void minimize(JFrame frame) {
int state = frame.getExtendedState();
// Clear the maximized bits
state &= ~Frame.MAXIMIZED_BOTH;
// Maximize the frame
frame.setExtendedState(state);
}
// This method minimizes a frame; the iconified bit is not affected
public void maximize(JFrame frame) {
int state = frame.getExtendedState();
// Set the maximized bits
state |= Frame.MAXIMIZED_BOTH;
// Maximize the frame
frame.setExtendedState(state);
}
</pre>
