Customizing for a touchscreen

Last year, my wife suffered a severe stroke and since that time she is almost unable to read books normally. Reading books was her biggest hobby.

After much experimenting we finally got some progress with the help of Calibre's ebook-viewer program. By carefully tweaking style sheets I can get results in terms of font, font size, line spacing, margins and so on; results that allow her to really read a real book for some 10-15 minutes, which is a great win already.

She uses a touchscreen PC (Tellus 3+ running Windows XP SP2) as a communications device and I would like to tweak the ebook-viewer a bit to make it more suitable for a touchscreen device. Note that (also due to the stroke) she is not able to click small buttons or use a stylus, and she cannot read standard dialogs. Also, the Tellus has no keyboard and no mouse.

The changes I'm considering are:
* start in full screen mode;
* show only a couple of relevant tool icons, and use bigger icons;
* add tool icons for partial page scrolling and section movement;
* add tool icon to exit.

I'm a seasoned programmer but I have no experience with python, so I kindly ask whether someone would be willing to spent a bit of time to help me accomplish this.

Thanks.

You will need to edit the file

src/calibre/gui2/viewer/main.ui using Qt Designer to change the layout and the file

src/calibre/gui2/viewer/main.py to write the logic for your new actions.

This is a patch against 0.7.23 implementing a command line option for ebook-viewer to start in fullscreen mode.
Feel free to incorporate it.
