Due to being a compositor, kwin has to conform to some certain
interfaces. It means a lot of virtual functions and function tables to
integrate with C APIs. Naturally, we not always want to use every
argument in such functions.
Since we get -Wunused-parameter from -Wall, we have to plumb those
unused arguments in order to suppress compiler warnings at the moment.
However, I don't think that extra work is worth it. We cannot change or
alter prototypes in any way to fix the warning the desired way. Q_UNUSED
and similar macros are not good indicators of whether an argument is
used too, we tend to overlook putting or removing those macros. I've
also noticed that Q_UNUSED are not used to guide us with the removal no
longer needed parameters.
Therefore, I think it's worth adding -Wno-unused-parameter compiler
option to stop the compiler producing warnings about unused parameters.
It changes nothing except that we don't need to put Q_UNUSED anymore,
which can be really cumbersome sometimes. Note that it doesn't affect
unused variables, you'll still get a -Wunused-variable compiler warning
if a variable is unused.
There were overflows in the bandwidth estimation calculation. To simplify things,
also only generate common modes if the display doesn't advertise them on its own
already.
Seems we can't have a plural with an argument in singular and not in the
plural
a format specification for argument 2, as in 'msgstr[0]', doesn't exist in 'msgid_plural'
msgfmt: found 1 fatal error
Makes it possible to follow the dbus service for locale configuration,
making it possible to have third parties integrate with Plasma.
This is done opt-in for now, it can be adopted generally in the future,
if necessary.
This rewrite ensures that
- formats are tested for multi-gpu transfer
- dmabuf with either 10bpc or 8bpc buffers are preferred to cpu copy
- formats where drmModeAddFB2 fails are skipped
kwin can crash for reasons that have nothing to do with compositing. If
that's the case, after two crashes compositing will be permanently
disabled and you would need to go to system settings to reenable it, the
timestamp based check in the x11 backend won't be effective.
CCBUG: 452344
We don't need to emit {x,y,width,height}Changed signals ourselves. We
also need to send an expose event otherwise the window can be rendered
incorrectly if it's resized. The logic follows QtWayland implementation.
With the pull approach, the XdgOutputV1Interface class doesn't have to
be exposed in the public api and can be made private to simplify the
implementation of the xdg-output-v1 protocol.
Currently, kwin will continue matching dnd actions after a drop. This is
mainly needed in order to make "ask" action work.
However, it appears like there are clients in the wild that update offer
actions after receiving wl_data_source.dnd_drop_performed and wl_data_device.drop
events.
One could argue that's a client bug, and perhaps it is, but the spec is
vague about that. In meanwhile, let's make sure that dnd action matching
is active after drop only when the selected data source action is "ask."
