When the output layout changes, the Workspace is going to update the
struts and then go through every window and see whether it should be
moved or resized.
On the other hand, the layer shell windows react to output changes on
a timer. Furthermore, it's not synchronized with the workspace rearranging
the managed windows. It means that when Workspace::desktopResized() runs,
the panel struts can be slightly outdated, i.e.
- An output layout change occurs
- Workspace::desktopResized() is called but the struts can be wrong
- some time later, LayerShellV1Integration::rearrange is called, it
fixes layer shell window geometries and struts
- after the layer shell integration has finished rearranging the
layer shell windows, it calls Workspace::desktopResized(), but the
damage had already been caused
With the proposed change, the Workspace and the LayerShellV1Integration
will rearrange the windows in sync.

At the moment, if the workspace extends or shrinks by an output, the
hidden panel will be shown. It doesn't make sense in all cases.
Furthermore, no screen edge will be reserved if the layer surface has
some margins.
To address that, allow "floating" panels reserve screen edges and also
make kwin try harder to preserve window edges if the output layout
changes.
CCBUG: 448420
Currently there is a 150ms delay before screen edge actions and
hotcorners are triggered; the cursor has to spend that much time there
before they'll activate. This is good for preventing accidental
activations, but also prevents and delays deliberate activations, which
are likely to be more annoying for the user.
To alleviate this, the delay is reduced to 75ms, which still prevents
most of the accidental activations in my testing, while making
deliberate activations faster and easier.
Makes it possible to easily target things in a window near your panel edge,
without bringing up your panel.
The `m_client` condition this MR removes appears to have been added solely to make autohiding panels appear instantly. See c4140d6f4e.
BUG: 267277
Window::acceptsFocus() is not taken into account when a window is
activated using Workspace::activateWindow(). The main reason is because
of different input models on X11.
Instead, Window::takeFocus() should check itself if the window accepts
focus.
The Effects API has one signal screenEdgeApproaching with effects
monitoring the last signal to stay in sync.
If an Edge is destroyed whilst visible, effects currently do not get
notified and it can stay there forever.
This patch emits screenEdgeApproaching if appropriate with a factor of 0
when an edge is destroyed.
BUG: 403354
Before Deleted merge, it used to be equivalent to waiting until the
window is closed.
This fixes tests waiting until the window closing animation completes
and the Window object is destroyed.
Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
We use the PMF syntax so the isValid() check is unnecessary as the
compiler will notify about wrong signal at compile time. It makes
writing autotests feel less boilerplaty.
Things such as Output, InputDevice and so on are made to be
multi-purpose. In order to make this separation more clear, this change
moves that code in the core directory. Some things still link to the
abstraction level above (kwin), they can be tackled in future refactors.
Ideally code in core/ should depend either on other code in core/ or
system libs.
This change adjusts the window management abstractions in kwin for the
drm backend providing more than just "desktop" outputs.
Besides that, it has other potential benefits - for example, the
Workspace could start managing allocation of the placeholder output by
itself, thus leading to some simplifications in the drm backend. Another
is that it lets us move wayland code from the drm backend.
With fractional scaling integer based logical geometry may not match
device pixels. Once we have a floating point base we can fix that. This
also is
important for our X11 scale override, with a scale of 2 we could
get logical sizes with halves.
We already have all input being floating point, this doubles down on it
for all remaining geometry.
- Outputs remain integer to ensure that any screen on the right remains
aligned.
- Placement also remains integer based for now.
- Repainting is untouched as we always expand outwards
(QRectF::toAdjustedRect().
- Decoration is untouched for now
- Rules are integer in the config, but floating in the adjusting/API
This should also be fine.
At some point we'll add a method to snap to the device pixel
grid. Effectively `round(value * dpr) / dpr` though right now things
mostly work.
This also gets rid of a lot of hacks for QRect right and bottom which
are very
confusing.
Parts to watch out in the port are:
QRectF::contains now includes edges
QRectF::right and bottom are now sane so previous hacks have to be
removed
QRectF(QPoint, QPoint) behaves differently for the same reason
QRectF::center too
In test results some adjusted values which are the result of
QRect.center because using QRectF's center should behave the same to the
user.
