This ensures that we get a warning if the config header is not included
instead of compiling the code as if it was disabled. Interestingly, some
checks already used #if KWIN_BUILD_*, so those were generating -Wundef
warnings when the feature is disabled. Commit 886173cab assumed that all
those features were already 01, so this unbreaks the build if any of the
features is disabled.
Fixes: 886173cab ("Reduce ifdefs in Workspace::supportInformation()")
It's leftover after the times when widget style was using wayland
connection. Breeze had to destroy all wayland resources before
terminating the internal connection.
Xcursor loading code has hardcoded search paths, in order to take into
account distros installing app data in a different location,
libwayland-cursor sets the ICONDIR to the icon directory computed based
on the install prefix.
However, that won't work with gitlab CI because it relocates binaries. A
more robust way to find cursors would be to use QStandardPaths to find
all the icon directories on the system.
Another advantage of using own cursor loading code is that it allows us
to reuse cursor images that are symlinks. For example, with
breeze_cursors, almost half of the files in the cursors directory are
symlinks.
The main disadvantage of this approach is that we would have to keep the
search paths up to date. However, on the hand, there are not that many
of them, e.g. ~/.icons, ~/.local/share/icons, /usr/share/icons,
/usr/local/share/icons. The last three are implicitly handled by the
QStandardPaths.
With the xdg_toplevel.configure_bounds support, the compositor is
finally able to tell the client the maximum recommended window size.
That approach allows us to keep the compositor side simple and it
prevents (as long as the app is well behaved) annoying visual glitches
such as mapping window with one size and then quickly resizing it to
the final size.
There are two operations failing currently, so we QEXPECT_FAIL
them for now:
- A new client is not moved to the screen set by the rule
(Wayland only). Affects Apply, Force and Remember
- Disabling and enabling an output will not move the client
to the Forced screen (On X11 and Wayland, BUG:409979)
If the user wants to move a tiled window, but changes their mind and
tiles the window back to the previous position, the geometryRestore()
will be corrupted because initialMoveResizeGeometry() is the same as the
geometry of the window in the tiled mode.
This change fixes tracking of the geometry restore by precomputing the
geometry restore when starting interactive move. That way, if the window
is untiled and tiled again without release left pointer button, the
geometry restore will be set to the correct value in setQuickTileMode().
This change also adjusts the test suite so such a subtle case won't be
broken again without noticing it.
It can also be applied to client-side decorations. As long as the
compositor can ask the client to use some specific decoration mode, the
"no border" property can be set.
If there's only one configure event that changes the position of the
window and it gets acknowledged but no buffer is attached yet, and a new
configure is sent, then the ConfigurePosition flag won't be inherited
by the new configure event and the window will be misplaced.
In order to fix that, this change makes XdgSurfaceClient pop the last
acknowledged configure event from the m_configureEvents list only when
it's about to be applied for sure.
BUG: 448856
Historically, noBorder() was used for two things:
* as a substitute for AbstractClient::isDecorated()
* to determine whether the AbstractClient should have a decoration
With async decoration updates refactoring, a few things around
noBorder() have changed, which exposed an existing bug in the handling
of borderless maximized windows.
It's possible to have a case where an initially maximized window makes
an xdg_toplevel.set_maximized request before the initial commit, but
creates the decoration object after the initial commit.
Since XdgToplevelClient::userCanSetNoBorder() would return false when
maximize() is called in XdgToplevelClient::initialize(), m_userNoBorder
won't be updated and therefore the window can end up having a server
side decoration.
Previously, it wasn't the case because kwin would do nothing if the
decoration is installed and its preferred mode changes after the initial
commit but before the surface is mapped. With async decoration fixes,
kwin would react as expected, which unfortunately has exposed the bug.
The root cause of the problem is the fact that noBorder() is overloaded,
which makes it error-prone.
This patch changes how the noBorder property is treated. Now, it only
indicates whether the compositor wants the window to have no borders. If
noBorder() is true, it means that the compositor doesn't want the window
to have a server-side decoration; on the other hand, if noBorder() is
false, it doesn't imply that the window should have a decoration.
BUG: 448740
geometryRestore() is no longer updated after mapping the window, so
setQuickTileMode() has to update geometryRestore() explicitly to the
correct value.
With this change, geometryRestore() will be updated as follows:
* if the window is tiled, geometryRestore() is valid, nothing to do
* the window has been dragged to the top edge, set geometryRestore() to
the geometry that the window had when starting move
* otherwise, use the current move resize geometry
dontInteractiveMoveResize() was added to workaround kwin sending bad
configure events when double clicking mpv to make it fullscreen.
With async geometry updates fixed, dontInteractiveMoveResize() can be
finally removed.
Another reason to remove dontInteractiveMoveResize() is that it can make
kwin crash with a debug build. For example, if you enable resizing
maximized windows in breeze decoration settings and resize a maximized
window, kwin would eventually crash in
the AbstractClient::handleInteractiveMoveResize() function because neither
isInteractiveMove() nor isInteractiveResize() return true.
On Wayland, the move resize geometry and the frame geometry are
completely out of sync.
This change synchronizes emitting of the clientStepUserMovedResized
signal to the move resize geometry changes.
It simplifies code of InternalClient and XdgSurfaceClient, and makes
adding support for other shell surface protocols easier as there's less
boilerplate stuff that you would need to take care of.
It's not practical, regular users don't care about window geometry. One
could argue that it can be useful for creating window rules, but window
rules kcm pulls relevant properties from kwin.
If needed, one can reimplement this feature as a QtQuick script that creates
an overlay window positioned above the window that is being interactively
moved or resized.
Same as real hardware wl_keyboard, key should be sent before modifier
change. For example, Left Ctrl press and release should produce
key events in the order of Control_L and Control+Control_L.
Observed in kdevelop, that isEnabled() could be false when switching
between different tabs with Ctrl+Tab. But Qt may still call show()
if you click on the texteditor widget. This leads to isEnabled == false but
setActive(true) is called. This causes kdevelop in a usable state because
keyboard grab will be created and no key event will reach application
because isEnabled == false. Under normal circumstances, key will reach
widget first and triggers another text_input_v2 enable to make input
method work properly.
text-input-v3 does not have preedit styling, instead, it can only
specify the range of cursor. Try to keep track of any
highlight/selection style range and combine them together. If it matches
the cursor position, use it as the cursor range.
Currently, if a window switches between SSD and CSD, it is possible to
encounter a "corrupted" state where the server-side decoration is wrapped
around the window while it still has the client-side decoration.
The xdg-decoration protocol fixes this problem by saying that decoration
updates are bound to xdg_surface configure events.
At the moment, kwin sort of applies decoration updates immediately. With
this change, decoration updates will be done according to the spec.
If the compositor wants to create a decoration, it will send a configure
event and apply the decoration when the configure event is acked by the
client. In order to send the configure event with a good window geometry
size, kwin will create the decoration to query the border size but not
assign it to the client yet. As is, KDecoration api doesn't make
querying the border size ahead of time easy. The decoration plugin can
assign arbitrary border sizes to windows as it pleases it. We could change
that, but it effectively means starting KDecoration3 and setting existing
window deco ecosystem around kwin on fire the second time, that's off the
table.
If the compositor wants to remove the decoration, it will send a
configure event. When the configure event is acked and the surface is
committed, the window decoration will be destroyed.
Sync'ing decoration updates to configure events ensures that we cannot
end up with having both client-side and server-side decoration. It also
helps us to fix a bunch of geometry related issues caused by creating
and destroying the decoration without any surface buffer attached yet.
BUG: 445259
The output management test checks the implementation of output
management capabilities in the virtual backend, which is not helpful.
This change replaces it with a more useful test that verifies how
windows are placed after an output change.
TestXdgShellClientRules implicitly assumes that the kwinrc config is
referenced only by the RuleBook object.
However, after changing the default placement policy in the
WaylandTestApplication, that's no longer the case. The kwinApp() object
now also holds a reference to the main config file. Because of that,
previous window rules leak to next tests, which breaks them.
In order to address that issue, this change makes TestXdgShellClientRules
open a separate config and wipe it clean after each test run. Not great,
but there doesn't seem to be other way around with current KSharedConfig
api.
It's more common to see the parent object being the last argument in Qt
and this way you won't need to specify nullptr parent explicitly if the
xdg-popup or the xdg-toplevel surface doesn't need to be configured
implicitly, which makes tests slightly easier to read.
Effect loading is already tested using integration tests, for example
the maximize test verifies that the maximize effect is loaded _and_ it
actually does something useful when a window is maximized or restored,
testScriptedEffectLoader only verifies that the effect is loaded, which
is less helpful than what integration tests provide us.
But perhaps the main problem with these tests is that they require us
building a mockverse around them. This litters code with ifdef
preprocessor directives and makes changing such code a living nightmare.
Another problem with these two tests is that they cannot use OpenGL
because it means mocking OpenGL, which we obviously not going to do.
With integration tests, it's not a problem.
The bottom line is that unit tests can be useful but they make life
notoriously difficult when it comes to testing components that depend on
other components.
Currently, kwin expects that the xdg-decoration is installed before the
initial commit. However, decoration tests do that after the initial
commit, which makes testMaximizeAndChangeDecorationModeAfterInitialCommit()
silently pass.
On a second look, it seems that the xdg-decoration spec is okay with the
xdg-decoration being created after the first commit (as long as it's
done before the surface is mapped). This needs to be fixed separately.
CCBUG: 445259
If the preferred decoration mode changes after the initial commit but
before the surface is mapped, there's a chance that kwin can send a bad
configure event, it's been the case in the past. Add a test to prevent
such cases go unnoticed.
If the decoration is destroyed before the window is mapped, kwin can
respond with a configure event that has 0x0 size. New tests check that
problematic case.
