Qt Platform for Kindle 2 & DX, plus Sudoku!

[Dzha]

@darron
I have stumbled across KindleScreen implementation in KindlDirectFB directory. It looks like an attempt to inherit KindleScreen directly from QScreen and do the blit/solidFill etc at low level skipping QLinuxFbScreen. It looks very interesting.
I wonder if I should even look that way with my amateurish skills in Qt! But ... can you please, tell me a little more about this plugin? Do you think it is possible to re-use the code and speed up painting operations? Or the gain will be negligible?

I was thinking about a solution for a while now. Ideas so far:

Solution 1: Patch QScreen (easy?)

• introduce virtual void QScreen::setFlashing(bool)
• empty default implementation
• overwrite setFlashing in KindleScreen
• set the flashing update once when the set to true and reset to false after the update
• get the static pointer QScreen::instance();
• use screen->setFlashing(true) before calling the update to do one flashing update

Solution 2: Intermediate class (better?)

• inherit QFlashingScreen from QLinuxFBScreen
• Introduce setFlashing in QFlashingScreen
• reinterpret_cast or dynamic_cast the pointer of QScreen to QFlashingScreen
• call setFlashing()
• enjoy flashing udpate

I think that I can possibly use QFlashingScreen in future for some other purposes as well (like hardware text cursor for example). So No2 looks good so far.

Hi!

Is there a package that will install on the DXG?

Thanks!

Right, I was successful in installing the packages on my DXG after repacking them with version 0.11 of the packaging tool (found it in this mobilread forum), but now I've hit another snag, the hotkeys don't seem to work. Nothing happens when I press 's+u' (press s, hold s, press u, release both s and u), or 's u' (press s, release s, press u, release u). The other key combinations do nothing either, not even r+s+t, which is supposed to reboot the Kindle, and should be quite noticeable.

What is supposed to happen anyway? Am I doing something wrong? I've installed the jailbreak first, does this work without it? And if I want to install the packages on the Kindle DXG, should I use the US, or the international version?

Thanks
