e564. Iconifying and Maximizing a FrameThis example implements methods to iconify, deiconify, minimize, and maximize a frame. In general, you should not make calls such asFrame.setExtendedState(Frame.ICONIFIED) because 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.
// This method iconifies a frame; the maximized bits are not affected. public void iconify(Frame 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(Frame 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(Frame 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(Frame frame) { int state = frame.getExtendedState(); // Set the maximized bits state |= Frame.MAXIMIZED_BOTH; // Maximize the frame frame.setExtendedState(state); }
