Is there anyway using Key.Control to determine if it is the left or the right control key being pressed?

You can differentiate using Key.LeftControl and Key.RightControl
(Untested)
Or something like that anyway.

 I don't think it's possible.

The gambas Key.class gives same code for both control keys.

same for Shift

Only Alt keys differentiate as one if Key.AltKey and other is Key.AltGrKey

It's a shame and certainly limits game control as i discovered on my TurboSnake game.

2 users sharing a keyboard cannot use Shift or Ctrl keys  well they can but it's dodgy

 So why do the constants exist? M Minisini needs to explain.
They definitely have different scan codes (that's the low level code that's received at the OS level). I know that from a looooooooooong time ago and in a far distant galaxy.
It should be possible!

 I'm pretty sure they don't m8.  (not sure what language that is but i don't think it's gambas)

I only see Key.ControlKey constant

I know you can send with x11 Desktop.SendKey("Control_L")

but there's no way to receive

Key.Code for both control keys are the same and its Key.ControlKey

Seems you can't do it because it's not a qt key code either

the Qt Key class only uses a Key_Control
Qt Namespace | Qt Core | Qt 6.9.2

there are ways to do it with the QT api but gambas Key.class does not do anything unusual, it only supports what the toolkit Key class supports in respect to Control and Shift Keys

No clue how to implement any of that  though

I am making a very simplistic pinball game, so I guess I will just use control for left flipper and alt for right flipper.
