Re: [platform-swt-dev] Getting multitouch gestures to work in SWT based

["Markus Keller" <markus_keller@xxxxxxxxxx>]

Gesture/Touch support for GTK has not been
implemented yet.

Filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=482018
and added a warning to the SWT API docs
in master.

Hello,

I'm trying to get multitouch gestures (rotate, pinch/zoom, swipe/scroll,
etc.) to work using SWT 3.8.2 (from debian package) on linux.
What I've done so far:
- Tried to run snippet353.java which seems to totally ignore any pointer
input.
- Tried to make sure mutitouch works on my xorg installation:
-- I've got an ELAN Touchscreen (04f3:016f) which is recognized by xorg's
evdev driver
-- 'xinput test' and evtest both spit out events as soon as I'm touching
the screen, even multitouch events (different slot-values and positions
for each finger)
-> everything seems to be fine with xorg
- I also wanted to make sure GTK+ itself is recognizing multitouch events:
-- I was looking for a multitouch-enabled GTK(+)-application and just found
this minimal 'touchy'-Python-app: https://gist.github.com/chergert/4344205
-> works like a charm (multitouch) under Xfce, but it's only single
touch under KDE (but that's not a problem, I will stick with xfce or even
just a bare xorg session)

So somewhere between GTK and SWT multitouch events seem to be lost. What
could be the cause or how can I further narrow down the problem?

Thanks in advance!
Regards!
Thomas
