When a floating dockwidget's title changes, it is rendered as a
window title. When the title changes while floating, the change will be
reverted to the pre-change title when the dockwidget is docked again.
This patch explicitly propagates the window title, if it has been

If an application sets the current index and resizes the tab widget
before showing it, then the scroll offset might be calculated based on
an old size. Since after ca15f650a1,
resizing explicitly avoids scrolling, this could result in tabs ending
up scrolled outside of the tab bar when showing the tab widget.
Fix that by explicitly making the current tab visible in the tab bar's
showEvent handler, which recalculates the scroll offset based on the
actual size.
This is only reproducible with a tab widget, which lays out the tab bar
for each change and resets the tab bar's layoutDirty flag. Add a test

QPixmapCache maintains a mapping from QString to QPixmapCache::Key, in

Refactor the 'CHECK' macro to eliminate the capacity check and
explicitly verify that no reallocation occurred. The previous
implementation had to pass constants to suppress the issue arising
from differing growth rates between implementations.
Additionally, improve the 'std::stringstream' versions of the test
by incorporating the correct values. In the previous implementation,
the usage of:
auto tData = V(9);
~~~
std::stringstream ss("9 9 ");
had several issues. Firstly, it used the wrong test data since the
container's value_type of '(char) 9' resulted in a tab character '\t',
which was not accurately reflected in the stringstream assignment.
Secondly, this value caused problems in how stringstreams interprets it.
To address these issues, let's make the following improvements:
1. Use a default test value of 65 instead of (char) 9. This value, which
represents the character 'A', is less likely to cause errors and is more
intuitive.
2. Use the tData variable for the assignments in the stringstream. This
ensures that the correct data from the container is used.
3. Change the test value between the assign() calls to verify that the
container's contents are successfully overwritten.
These changes ensure, that the test cases are more accurate and
reliable.

This patch relaxes the requirements on the context object of
continuations. Instead of having to stay alive during execution of the
whole chain, it now only has to stay alive during setup of the chain.
If the context object is destroyed before the chain finishes, the
respective future is canceled.
This patch works by using QFutureCallOutInterface and signals instead
of direct invocation of the continuation by the parent future, similar
to how QFutureWatcher is implemented.
If a continuation is used with a context object, a QBasicFutureWatcher
is connected to the QFuture via a QFutureCallOutInterface. When the
future finishes, QBasicFutureWatcher::finished() triggers the
continuation with a signal/slot connection.
This way, we require the context object to stay alive only during setup;
the required synchronization is guaranteed by the existing event and
signal-slot mechanisms. The continuation itself does not need to know
about the context object anymore.

In QAccessible's widget implementations, trees are treated as tables,
with a rowCount implementation that is based on the view's current
item content. That item content is the view's content, not the model's,
and it changes when tree branches are expanded.
The Cocoa bridge for accessibility allocates arrays of row data
structures based on the rowCount implementation. Those data structures
need to be invalidated and recreated when the view's content changes.
To do that, emit an accessibility event for a model reset when laying
out items changes the size of the view's item array. We don't know what
changed during that layout process to makes this any more granular.
Amends 11ae55e918, but the problem
with the data structure being stale and incorrect would have been there
before that chain of changes optimizing. It didn't trigger an assert,
but probably resulted in incorrect data being reported.
To make trees testable, we need to actually expose them as AXOutline
to the macOS accessibility framework. Until now, they have been treated
like plain QWidget, e.g. AXGroup. This made them in practice in-
accessible. With this change, VoiceOver works much better (although not
perfeclty yet).
Also remove an assert that could be triggered by an accessibility
client asking for a cell for an invalid index (which can be reproduced
by navigating around in a tree, following debug warnings from
