We ported a qt desktop app to Maemo, Android and Symbian.
The app supports zooming and panning of the whole window contents.
In the desktop app we use
Ctrl+MouseWheel for zooming in/out.
Alt+MouseWheel for panning left/right
Shift+MouseWheel for panning up/down
We would like to map these functions to mobile devices.
Is there a portable method to do this on mobile devices ?
Where can i see a table of which gestures are available on which device ?
Where can i see a table of which hardware keys are available on which device ?
