[PATCH 08/10] weston: Port Wayland backend to new output handling API
Armin Krezović
krezovic.armin at gmail.com
Thu Aug 11 15:34:03 UTC 2016
This is a complete port of the Wayland backend that
uses recently added output handling API for output
configuration.
- Output can be configured at runtime by passing the
necessary configuration parameters, which can be
filled in manually, obtained from the configuration
file or obtained from the command line using
previously added functionality. It is required that
the scale and transform values are set using the
previously added functionality.
- Output can be created at runtime using the output
API. The output creation only creates a pending
output, which needs to be configured the same way as
mentioned above.
However, the backend can behave both as windowed backend
and as a backend that issues "hotplug" events, when
running under fullscreen shell or with --sprawl command
line option. The first case was covered by reusing
previously added functionality. The second case required
another API to be introduced and implemented into both
the backend and compositor for handling output setup.
After everything has been set, output needs to be
enabled manually using weston_output_enable().
