Hehe, I guess I'll write a separate dfb driver when I get this to work..
My temporary solution is now to modify the dfb keyboard driver to listen
for changes on my own linux device, and generate keyboard signals for
the cursorkeys, tab and enter when the buttons are pushed. Is there a
list of the keycodes i can use for "DFBInputEvent.key_code" ?
I tried to set an event.keycode to 9(for tab) as shown below, but I got
no response in my gtk application as you would expect with a "tab"
keypress/release.
code in thread-loop in function keyBoardEventThread()
(inputdrivers/keyboard/keyboard.c):
-----
read(fd, buf, 4);
if(~buf[0]&0x02) {
evt.key_code=9; //button 0 pushed, keycode=9 for 'tab'
evt.type= DIET_KEYPRESS;
evt.flags=DIEF_KEYCODE;
evt.key_code &= 0x7f;
dfb_input_dispatch( data->device, &evt );
}
------
Any views/comments here?
DFB and gtk is up and running on the AVR32 btw.
