multitouch input handling help required

Tue Jan 27 06:22:57 PST 2015

Hello Vikas,

In genivi we stopped a active development on  LayerManager also a X11 is not widely used in the automotive.
The current way to go for us  is a wayland compositor and we working on implementing ilm API on top of weston.

Therefore there is no effort spent to realize you use-case, sorry for that.

Best regards

Subject: multitouch input handling help required

Hi,

I am running GENIVI Layermanager (i.e. window manager and compositor based on GLES2.0 and X11) which doesn't support multi-touch event (i.e. Xi_TouchBegin, XI_TouchUpdate, XI_TouchEnd) handling and I have a requirement to support X11 based application with multi-touch (i.e. pinch and zoom use case with navigation) on top of compositor.

Layermanager X11 code: http://git.projects.genivi.org/?p=layer_management.git;a=blob;f=LayerManagerPlugins/Renderers/Graphic/src/WindowSystems/X11WindowSystem.cpp;h=cd6d5d4cfe0ab713b1d0cb61225fef1498cee454;hb=5e2f490b40b8b60a0efbd2b244be44d93bc081f6

I tried to add the support for Xinput 2 in layermanager but as there is no way to send the XI events using XSendEvents, I am currently looking for alternative way (or some hack) to make it work.

Could you please give your inputs, suggestion or ideas? Is this possible (i.e bypassing someway the compositor for particular application for input handling or modifying compositor or app for this purpose, but compositor must be running)?

If you know some mailing list where I can discuss this, could you please suggest?

Thanks for your time.

Thanks & Regards,
vikas
