Swing Window States

[Ender Valencia]

Hey everyone,

I wrote some code to override the JFrame's minimize event, but I am not sure it is the best it could be.

private void formWindowStateChanged(java.awt.event.WindowEvent evt) {
 
     System.out.println(evt.getNewState());
     
     //System.out.println(this.isShowing());
     if(evt.getNewState() == 1 && traySupported){
         //Do some stuff
     }
}    

The part I know could be better is the == 1. Is there a constant I can compare to to tell that the JFrame is minimized? What is the proper way to tell if a JFrame is minimzed/maximized.

Also, once it is minimized, how can I force it to maximize/restore?

Thanks!

Using Frame's get/set extendedState method ,it would be possible .

More info can be found at Frame docs

You should look at java.awt.Frame for the constants; in this case Frame.ICONIFIED.

For setting the new state there is method setExtendedState that takes these values as well - Frame.NORMAL, Frame.ICONIFIED, Frame.MAXIMIZED_HORIZ, Frame.MAXIMIZED_VERT and Frame.MAXIMIZED_BOTH.

Thanks,

I had a feeling Iconified was the one I needed, but wasn't sure based on the name.

I have it working just fine now. I minimize to the system tray and then maxmize from the tray.
