Re: Using touchscreen with headless system

[Elias Bakken <elias bakken gmail com>]

Lionel, I have tried connecting "event" to the stage and also "gesture-begin" as a test without any luck. Based on your message now I also discovered "touch-event", which seemed promising, and also the "captured-event" but I was unable to get any output from that either..

I'm using Clutter 1.16 and I am on a headless system, not X nor Wayland, directly on the framebuffer. (BeagleBone Black)

Hi Elias,

I had touch events to work on a touch screen laptop last month.

What signal are you connecting? Because touch events happens on a different signal from the one for mouse events.

What version of Clutter are you using?

Are you embedding Clutter into a Gtk window?

Cheers,

Hi!
I'm trying to get some basic functionality going with a touch screen. The device seems to be working fine using evtest and X but when trying to connect a signal (event) to the stage, nothing happens. A normal mouse seems to be working fine. Looking at the list of devices coming from the DeviceManager, I see the touch screen is found and has type CLUTTER_TOUCHSCREEN_DEVICE and is enabled. The core pointer also lists both the mouse and the touch screen as slave devices.

Does anyone have any pointers (pun intended:) for this?

I'm using Python as a language binding.
