M1+Q or M1+Z don't call respective handler [message #1835275]

Hi,
I'm struggling with 2 keybindings on macOS with e4 + JavaFX.

I setup M1+Q to call my ExitHandler and M1+Z to call my UndoHandler.

M1+Q quits the app but without calling the handler :-(

If I replace M1+Q by M1+F it works fine, my handler is really called.

For M1+Z nothing happens at all, if I replace Z by U, it works fines.

Both keybinding sequences seem to be" eaten" by another behavior.

Does anyone have an idea of which layer is overriding these sequences ?

Thanks,
Stéphane.

on M1+Q: As this is a native callback I think this command does not even reach us?
on M1+Z: So what keyboard layout (from your name I guess you have a french layout, right?) - the this is a JavaFX bug you can try in a simple JavaFX application and see what key you really get. On my german layout it is Y because Z and Y exchanged on my keyboard - I've reported a long time ago

Hi Tom, thanks a lot for your answer.

M1+Q fixed by injecting an IWindowCloseHandler in the context from protected void preLifecycle(IEclipseContext appContext) my class extending E4MainThreadApplication. This handler is called from DefWindowRenderer that registers its own handler on stage.setOnCloseRequest().

Yes you're right, I have a french layout mac keyboard i.e azerty layout.

M1+z --> got a w instead of z. Then i've changed the definition in Application.e4xmi and it now works with the 'z' key :-)

I will see to inject this keybinding from code if runtime platform is mac.

Thanks for your help.

you can adjust the model as part of a processor you contribute through the model-extension points, using an addon might not work as the model might already have been analyzed by othern addons

Hi,
To override M1+Z :
In fact, I provided a LifeCycleURI class through plugin.xml of my app as a property of my product extension-point.
In that class, I implemented a method: @ProcessAdditions void buildApplicationModel(final MApplication application) in which if platform is macOS, I replaced the sequenceKey M1+Z by M1+W for keybindings defined in Application.e4xmi file.
With that 'command' key + Z works, even if the displayed key binding in related Menu Item displays 'command' key + W.
Maybe, one day JavaFX will fixed that.
