Hi, I made first simple application to test touchscreen. It doesn't give me much hope about multitouching, but maybe we can discuss better if we have something.
http://cc.oulu.fi/~rantalai/freerunner/touching/ It is gtk program which prints 1) mouse location 2) mouse button press (and its location) 3) mouse button release (and its location) Compiling for Moko: . /usr/local/openmoko/arm/environment-setup make Compiling for Computer: comment out 'CC = arm-angstrom-linux-gnueabi-gcc' on Makefile make I made these test with OM2008.12. If you have time check what your distribution says. Usage: ssh -X r...@moko Case A) [ using computers screen and mouse ] ./touching_test Move mousepointer to window, press button down, move pointer, release button. Terminal output: Pointer moving at (17, 11) Button pressed at (17, 11) Pointer moving at (18, 11) Pointer moving at (19, 11) Pointer moving at (20, 11) Pointer moving at (29, 11) Pointer moving at (43, 11) Pointer moving at (51, 11) Pointer moving at (69, 11) Pointer moving at (89, 11) Pointer moving at (99, 13) Pointer moving at (109, 13) Button released at (113, 13) Pointer moving at (112, 13) Pointer moving at (112, 12) Case B) [ using touchscreen ] DISPLAY=:0 ./touching_test Put stylus somewhere, move it, release it. Terminal output: Pointer moving at (113, 101) Button pressed at (113, 101) Pointer moving at (112, 102) Button released at (436, 103) Case C) [ touchscreen with two stylus] DISPLAY=:0 ./touching_test Put 1st stylus somewhere in top left (and do not release it) Terminal output Pointer moving at (37, 20) Button pressed at (37, 20) Pointer moving at (42, 26) (Start all subcases 1st stylus is in top left) Subcase 1) Put 2nd stylus somewhere in bottom right Terminal output <NOTHING> Subcase 2) Put 2nd stylus anywhere and move it, release it, put it again, move etc. Terminal output <NOTHING> Subcase 3) Put 2nd stylus somewhere in bottom right. Release 1st stylus Terminal output <NOTHING> Release 2nd stylus Terminal output Button released at (454, 438) Subcase 4) Put 2nd stylus somewhere in bottom right Release both in ~sametime Terminal output Button released at (216, 363) <midpoint> Case B was something which breaks my plans how to implement multitouch. (It doesn't give any messages when dragged) btw: If this doesn't work with GTK, can it work some other way?
