Hello community,

I know it's probably not a bug and it work as intended but the overwrite of virtual key method on GlCtrl inheriteds class don't work !
Instead, to manage keytboard input event on the GLCtrl I need to install keyhook like that :
{
 //Constructor of my GlCtrl inherited class
	InstallKeyHook(&OpenGLExample::CtrlKeyHook); //Activate KeyEvent

}

//Static method of my class
static bool CtrlKeyHook(Ctrl* ctrl, dword key, int count)
	LOG("A key have been pressed !");
	return true;
}


But, since all mouse event can be properly overwritten in GLCtrl inherited class, why those key method can't be ?

Thanks in advance

Xemuth

Does it have a focus?

Hello Mirek,

In my opinion yes since all MouseMove is triggered.
To try it from your side, open "OpenGL" exemple in reference and add this method in OpenGLExample class :
	virtual bool Key(dword key, int count) override{
		Cout() << "Key Pressed !" << EOL;
		return false;
	}

you will see it wont work.

Because it does not have focus. Try

GUI_APP_MAIN
{
	Ctrl::GlobalBackPaint();
	TopWindow win;
	OpenGLExample gl;
	gl.SetFrame(InsetFrame());
	win.Add(gl.HSizePos(10, 10).VSizePos(10, 10));
	win.Sizeable().Zoomable();
	win.ActiveFocus(gl);
	win.Open();
	win.Run();
}

Thanks Mirek for having solve my problem,

Another quick question, if the Ctrl didn't had focus before, why mouse event where working fine ? Isn't Mouseevent supposed to require focus ?

Thanks in advance,
Best Regard.

No, focus is just for keyboard.

BTW, things were a little bit complicated, the real reason why your code was not working outright was NoWantFocus flag in GLCtrl. That prevented TopWindow to assign focus to it on open. I had decided to remove this flag, so your original code would work as is.
