Hello.
I was trying to understand what is the minimal code needed to get a
square painter on the screen. However, although I can make the client
talk to the Weston compositor, enumerate the global objects, etc, I
can't still see my surface drawn in the compositor scene.
The steps that my program makes so far are as follows:
- call wl_display_connect(NULL)
- call wl_display_get_registry(display)
- Install listeners for the registry that wl_registry_bind() many of
the advertised objects. However, I'm not listening to the events of the
objects advertised by the registry. Is it needed?
- call wl_display_dispatch() and wl_display_roundtrip()
- call wl_compositor_create_surface()
- mkostemp() a file and ftruncate() it to some 10MB or so
- mmap() the entire file created
- call wl_shm_create_pool()
- call wl_shm_pool_create_buffer()
- call wl_display_dispatch()
- Fill the buffer with some content. I filled it entirely with pattern
0x40404040.
- call wl_surface_attach(surface, buffer, 0, 0)
- Then the program just sits in an infinite loop...
Am I missing anything?
Sorry for my poor English (assuming that you think it's poor)....
