This code should give you a start:

If so, the code below on a button will swap the desktop the button is contained in between full screen and windowed modes. from javax.swing import JFrame window = system.gui.getParentWindow(event) while not isinstance(window, JFrame): window = window.getParent() if window.isUndecorated(): # Switch to windowed mode. window.dispose() window.setUndecorated(False) window.setExtendedState(JFrame.NORMAL) #…

You'll need to figure out how to capture your triggers for maximizing, get the parent JFrame of the window, and then just use this part, where `window` is the parent JFrame you want to maximize:

```auto
window.setExtendedState(JFrame.NORMAL)

```
