what would be the bet way to implement this in to SDL? for all the Ports.
i am right now in research on doing a touch controler but theres no document.

Control methods are one of my concerns too. It's not much of a problem on the N950 but we need to make our ports suitable for keyboard-less N9. It would be great if we had a common solution to avoid duplicating efforts.

We really do need some sort of touch controller. Something that allows us to divide areas of the screen into touch buttons which can be mapped to keyboard keys or joystick/joypad buttons.

Something like Accelemymote would help a lot. Is anyone working on a Harmattan port of this or something similar? The original developer (Flandry) doesn't seem to be on the community device program.

The virtual keyboard would be unsuitable in many scenarios but would be very useful whenever text entry is required. What would we need to do to display the virtual keyboard from within an SDL app?

Bluetooth or USB keyboards should work but would not be the ideal solution.

That is not in my plans at the moment, mostly because doing it is easy enough -- see DrNokSnes, where I did that already for N800 users.

In fact, the same code I used for that in DrNokSnes works already on the N950, and thanks to the time I spent getting multitouch to work on the N950 SDL , the touchscreen controls on DrNokSnes are already multitouch enabled on the N950 -- meaning I can finally play Mario Kart using touchscreen controls alone, and all of this before starting hacking on DrNokSnes.

On Harmattan the accelerometer should already be available as the first joystick device.

I did some experiments with this on Fremantle and Diablo: http://javispedro.com/maemo/captures/dosboxhwr.png

I did never really release that because h-i-m was crippled in the sense that you could not get individual virtual keydown/keyup events, but rather text events. The Meegotouch input method/Maliit is way better in that regard. I will do this, but it'll probably only happen after the N9 is released since it's not prioritary atm.

I understand this is probably more simple than what you want, but I made a few weeks ago this program that is a very simple multitouch "doodle" SDL application. It shows how to distinguish multiple fingers using this (or WebOS') SDL.
It works on both the N950 and the Meego IdeaPad.

(If you are interested on why I draw that pattern on the videos, it's because of an old lcuk joke ).

So what is working version of this sdl-gles example (from post14)?

I tried to add missing lines to initGL, but didn't get it working:
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 8);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 1);

It doesn't create window, but I can see
16637 frames in 5 seconds = 3327.4 FPS
19617 frames in 5 seconds = 3923.4 FPS
19637 frames in 5 seconds = 3927.4 FPS
...

And it stops when screen is touched (as expected).

I used png-image which is 256x256px.

[javispedro]

See post 19. You need to do all SetAttribute calls before SetVideoMode.

Also, there is no need for GL_DOUBLEBUFFER; it is always enabled on the N950.

Yes, this means you cannot disable vsync on the N950. Curiously enough, we've gone from not being able to enable vsync (N900) to NOT being able to disable it (N950). Fun stuff!
At least, vsync-ed OpenGL is a great pleasure. But SwapBuffers() will _sleep_ if you try to do more than 60fps., take that into account if benchmarking!

I modified Fremantle example, and it is working on N950 / Harmattan: http://wiki.meego.com/SDL_Gles

To get sound in Frogatto, I followed javispedro's advice and just compiled sdl-mixer1.2 from debian unstable (1.2.8-6.3) with the following changes:

I guess libsmpeg and libmikmod support should be added back, and maybe harmattan resource policy support, but maybe this is good enough for a start.

@javispedro
.deb libsdl-image1.2 has an issue with the the control (a little one) its depending on libsdl1.2debian (>> 1.2.4), if Im not mistaken shouldn't it be depending on libsdl1.2 (= 1.2.14-0maemo3)?
