is it possible to create a new event for xcb_warp_pointer, i want to be able to move the mouse cursor, also is it possible to provide some examples on creating new key press events. thanks in advance.

  1. Moving the mouse cursor with xcb_warp_pointer: This functionality is implemented as a WarpPointer in the XGB library here: https://github.com/jezek/xgb/blob/master/xproto/xproto.go#L14874C6-L14874C17

    I don't really know if it works. In the past, I've used the XTEST extension for simulating mouse movements. You can see how I used it in my xgo project (I did as exercise to learn more about xgb): https://github.com/jezek/xgo/blob/master/pointer.go#L117

    But it won't work under wayland + xwayland.

  2. Creating new key press events: I've done it using the XTEST extension too. You can see an example of how I handled this in xgo for key press simulations here: https://github.com/jezek/xgo/blob/master/keyboard.go#L141

    Creating key press events is a bit more tricky, if you need to simulate keys that aren't currently mapped. I've tried to solve it in the file linked above, but it wasn't 100% reliable, if I recall correctly.

    Again, this won't work under wayland + xwayland.

If you get something working and feel free to report and maybe add some examples yourself. I'd be happy to merge them.
