Launch applications by gestures.

[peterhey]

The touch device supports gestures. We can use it also to launch applications.

Define your applications in case section.

# gesture file

#!/bin/sh

# we have 9 gestures
#
# first four
# pinch + up
# pinch + down
# pinch + left
# pinch + right

It works with Launcher http://yifan.lu/p/kindlelauncher/
I don't know why it isn't working with KUAL. Some hints?

In this way we can open another application without closing app which we currently use. Or launch any script when the lack of access to menu. Many possibilities.

But it's far from perfect. One issue, framework hangs up when book and kterm are opened simultanously. Free to develop.

It starts automaticly after reboot when is on. Off state disable it.

Tested at K5 touch only. Autostart could bring some issue. So, if you have doubts, wait for feedback from other users.

Works with KUAL. The reason was '&' with launching script in 'menu.json'

Beneath I showed how easy can add new dedicated gestures. Another gestures are intended for 'Graphic Notes', based on native 'Xtestlab126'. To start it, use pinch + up gesture.

You can also run 'Gestures' and 'Graphic Notes' without install in autostart.

When the 'Midori' was launched and then closed, 'Gestures' will be stopped because of 'killall tail' in 'runit.sh' - midori file. Simplest way is replace 'killall tail' on 'killall parselog'. It's example.

1 nicer way to refresh
2 completly delete note
3 bypassing 4k pipe buffer, to use the location of the touch in real-time
