I use a Swing-based command line for testing new game features.
Unfortunately, typing in this command line also provides input to my unfinished Liti-engine based UI.
This is annoying.
I'm looking for some general fix for this. Is there a configuration setting that disables keyboard input when the game window is not in focus?
Or maybe a toggle that would let me turn on and off input at will?
I looked, but couldn't find any.
I can easily make a check if the command-line is in focus, but I'd rather not copy-paste that check in every key listener method.
I got the command line's controller class hooked up to the game loop, so if a toggle exist, I could insert it there.

The only thing that I can think of right now that works is to set the enabled state of your current ~~~~Screen which would inherently also set the state on all ~~~~GuiComponents.

Game.window().getHostControl().addFocusListener(new FocusListener() {
 @Override
 public void focusLost(FocusEvent e) {
 // whenever the game window lost focus
 Game.screens().current().setEnabled(false);
 }
 
 @Override
 public void focusGained(FocusEvent e) {
 // whenever the game window gains focus
 Game.screens().current().setEnabled(true);
 }
});

I think the TextFieldComponent might need some work in that regard and I don't even think there should be an option. Overall, text input should just not be processed when the GameWindow.getHostControl() is not the focus owner. Also the GameWindow should probably expose the focused events.
