[Bug 1307701] Re: xserver mouse pointer emulation from touch breaks with QML app.

 

Is there a specific reason for calling XISelectEvents() for each slave
vs using XIAllMasterDevices in QXcbConnection::xi2Select() in Qt?

  xserver mouse pointer emulation from touch breaks with QML app.

Bug description:
  When running an SDK app on the desktop, it's not possible to use the
  touchscreen to move windows, use the launcher, etc. The SDK app seems
  to consume all touchscreen events.

  To reproduce:
  1) On a desktop/laptop with a touchscreen (I am using a Dell XPS13), install 14.04 and check that the touchscreen works for moving windows
  2) Install the camera-app package from universe (I have 2.9.1+14.04.20140331-0ubuntu1)
  3) Launch the camera app
  4) Touch once inside the camera-app window
  5) Use the touchscreen to drag the camera-app window

  Expected results:
  You can move the camera-app window using the touchscreen

  Actual results:
  You cannot move the camera-app window, or perform any other touch tasks in unity, with the touchscreen

  This only affects touchscreen input - mouse/touchpad input is not
  affected

  This affects all apps written with the SDK (I tried camera-app,
  gallery-app, reminders-app). It's 100% reproducible.
