G4P how to get a key event on second GWindow

in Contributed Library Questions • 9 months ago

Hi I've created a second window using GWindow.
Now I need to get a key event (Control key) when and only when this second window is focused.

Do you think that could be possible?

Thanks, Davide.

Yes

Look at the window stater example to see how the mouse handlef is added. The keyboard is similar but use the addKeyHandler method.

Thanks so much!
that's how i wrote it.
Please can you tell me if everything is correct?

GoWindow = new GWindow(this, "Yes it works!", 0, 0, goWinX, goWinY, false, JAVA2D);
GoWindow.addKeyHandler(this, "GoWindow_KeyEvt");
void GoWindow_KeyEvt(GWinApplet appc, GWinData data, KeyEvent event) {
if ((event.getAction() == KeyEvent.PRESS) && (appc.keyCode == CONTROL)) {
println("CTRL Clicked!");
}
else if ((event.getAction() == KeyEvent.RELEASE) && (appc.keyCode == CONTROL)) {
println("CTRL Released!");
}
}

If the println statements worked then the code works - no problems!
