Does your text in DirectFB-evas show up correct? Doesnt here, tried
differnt stuff with the code but just wont work....

The problem was that DirectFB-evas couldnt load eet images.. I added
support for doing that in DirectFB-evas. Or do you think it would be a
better idea to add an eet-imageprovider to DFB? (sort of difficult with
the keys although I could try to persuade the DFB developers to let me
add support for spescifing keys)
oh and it be REALLY helpfull if evas was more verbose on errors such as
not beeing able to load an image of a certain format.. or some other
sort of error handling (or am I missing something as always..?) maybe
edje should be the one telling about the error..
Ive gotten the whole edje test program to function with input and all,
although at the moment the code is not very clean. Ill clean up quite a
bit and send a patch :)
But before that Id like to know from you if my solution to DFBs lack of
select is approriate:
- Create a unix socket (/tmp/.ecore_dfb ?), create a thread.
- in thread: connect to socket, while(wait for even) { send a byte to
socket; wait for socket to return a byte }
- the other end of the socket is connected to ecore.
- in the fd/event handler: get event, process event, send a byte to
socket (the thread receives it)
comments?
by god edje is a nice peice of work dude! im luuuvin it, dadadadadah
