Axel Spoerl 729e23f15f QPlainTextEdit: update viewport, when placeholder text disappears
QPlainTextEditPrivate::updatePlaceholderVisibility() issued a full
viewport update, when the document became empty and the placeholder text
needed to be shown. No update was issued, when the placeholder text was
replaced by a first text character entered.
That relied on the assumption, that the placeholder text would disappear
with the first text line being rendered (even if it has just one char).

When the placeholder text covered multiple line, only the first of them
disappeared.

This patch adds a boolean to remember, that the placeholder text is
shown. If that is the case and the first char is entered, a full update
is issued, to remove all lines of the placeholder text. The boolean flag
is cleared thereafter, to avoid unnecessary viewport updates.

isPlaceHolderTextVisible() is renamed into placeHolderTextToBeShown(),
because the method returns an instruction, rather than a state.

tst_QPlainTextEdit::placeholderVisibility() is adapted to test the
boolean flag, hence the real visibility of the placeholder text.
That extends its scope to the bug at hand.

Volker Hilsheimer 4f95e66f94 QWidget: deliver DragLeave events symmetrically
If a widget received a DragEnter event that it didn't accept, then the
UnderMouse widget attribute gets set. But the drag manager never got a
drag target, so the DragLeave event was never delivered, leaving the
UnderMouse attribute set incorrectly.

We always need to send DragLeave events to the receiver, even if the
DragEnter or DragMove was not accepted. Otherwise we are not in balance,
and the UnderMouse attribute will remain set.

This is a change of behavior and a very old bug, so only fixing this in
unreleased branches. Test case added to verify that explicitly generated
drag events result in the correct enter/leave events.

[ChangeLog][QtWidgets][QWidget] DragLeave events are now always sent to
the widget the mouse is leaving, even if it didn't accept the DragEnter
event.

Axel Spoerl d4f38a3632 QDialogButtonBox: Fix focus chain and default button assignment
QDialogButtonBox::layoutButtons() rebuilds the focus chain based on the
button layout. It relied on the fact that the last button in the layout
would point back to the first button. That is not the case, if
- a focus frame gets inserted in the chain, and
- the default button is not at the layout's first (=left) position.
In that case, the chain stops at the button left of the default button.
The default button can not be reached by tabbing forward. Back-tabbing
still worked.

By not "closing" the focus chain, the focus proxy was set to the first
button found in the layout. That is wrong, whenever the default button
is not at the first layout position. When the box got focus for the
first time, pressing "Enter" could lead to a non-default button being
triggered. A Yes/No message box would have No as its default button.
On Linux, it would pop up with "No" being highlighted, but "Yes" having
focus. Pressing Enter would trigger Yes, instead of No.

tst_QMessageBox::staticSourceCompat() heuristically defines the
button expected to be triggered by Enter. On Linux/KDE, it would pass,
when the wrong button was fired.

=> Always "close" the focus chain, by linking the last and first
buttons.
=> Make the default button the button box's focus proxy.
=> Change tst_QMessageBox::staticSourceCompat() to always expect No
being fired by Enter in a Yes/No box.

[ChangeLog][QtWidgets][QDialogButtonBox] Default button becomes
focus proxy of a QDialogButtonBox. This ensures that Enter triggers
the default button, instead of the first button in the layout.

Tor Arne Vestbø 5b09d9e6d6 Sync QWindow visible state during QWidget destruction
A call to QWidget::destroy() will end up in QWindow::destroy(), which
calls QWindow::setVisible(false).

A call to QWindow::setVisible(false) on a widget's window will under
normal circumstances end up in QWidgetPrivate::setVisible(), which in
turn recurses back into QWindowPrivate::setVisible(), via
QWidgetPrivate::hide_helper(), ensuring that the QWindow internal
state is updated, visibleChanged emitted, and show/hide events sent.

Durin QWidget::destroy() we end up in QWindow::destroy(), which calls
QWindow::setVisible(false), but in this case the widget no longer has
Qt::WA_WState_Created, so the hide_helper() call is skipped, and the
corresponding QWindow is not kept in the loop.

To work around this we could have checked for windowHandle() instead
of Qt::WA_WState_Created before calling hide_helper(), but that had
many other side effects, so we opt for a more targeted fix.

Tor Arne Vestbø 13074a967f Debounce QDeferredDeleteEvents in QObject::deleteLater()
We used to look through the event queue in QCoreApplication::postEvent,
and if we found an existing DeferredDelete event for the receiver we
would compress the two events into one.

This was changed in 99b89d30fa, as the
logic was causing O(n^2) for deleteLater, by using one of the bits
in QObjectData to track whether the object had already been deleted.

But it kept the logic for tracking this in QCoreApplication::postEvent,
and QCoreApplication::compressEvent would still do the work of deleting
the additional QDeferredDeleteEvents.

To avoid the unnecessary heap allocation of the QDeferredDeleteEvents
we can move the debouncing/compression to QObject::deleteLater().
We use the same mutex as in QCoreApplication::postEvent to guard
concurrent access to deleteLaterCalled.

A note has been added about the (preexisting) issue that the mutex
is not sufficient to prevent data races, as the deleteLaterCalled
flag is part of a bit-field, and we're not guarding any of our
other accesses to other bits.

As QDeferredDeleteEvents is private API, we can rely on no-one else
posting it than QObject::deleteLater(), which should be the case now
that tst_QApplication::sendPostedEvents() was fixed.

The documentation has been clarified as well. It's safe to call
deleteLater() more than once, but that's not _because_ other
pending events for the object are cleared. The latter behavior
is normal ~QObject() behavior. The documentation was probably
written at a point we didn't do any event compression at all
for QDeferredDeleteEvents.

Volker Hilsheimer 0441526448 QAIV: reset state if removing index while editing or committing
If the commit of data to a model index result in that index getting
filtered out, then the editor will be removed as part of committing the
data, and the index that the editor is associated with becomes invalid.
The subsequent call to closeEditor() will find that the index for the
editor is no longer valid.

This should not warn, and it should also not abort the clean-up process
early. Instead, identify that the editor that we want to closed is
already hidden. In that case, skip the warning and most of the cleanup
process, and proceed directly to the EndEditHint handling further down.

Add a test that simulates the two scenarios where this can happen:
either the committing of data results in the index being filtered out
by the existing filter; or the filter changes while editing, and the
index being edited gets removed. In both cases, we don't want to see a
warning, and the state of the item view should be reset correctly.

Axel Spoerl 7835f9e601 QSplashScreen: Enforce visibility by processing events
A splash screen is usually shown during initialization, before the main
window is shown. At that point, an application might not spin an event
loop. The documentation therefore recommends to run processEvents()
periodically, in order to ensure that the splash screen is actually
shown. Async window managers (e.g. XCB) might require more than one call
to processEvents() for the splash screen to be shown. It can't be
guaranteed, that a specific number of calls to processEvents() make the
splash screen visible. Calls to processEvents() are not considered
good practice in application code.

QSplashScreen::finish() uses a copy of QTest::qWaitForWindowExposed(),
to automatically close the splash screen, when the main window is
shown.

=> Re-write the static inline waitForWindowExposed to wait for the
widget's windowHandle()->isVisible(). That ensures visibility to the
window system.
The previous version waited for isExposed() to become true. That
ensured exposure to the application, but not visibility.

=> Intercept QEvent::Show and process events, until the splash screen
becomes visible.

=> Remove references to processEvents() as a requirement to show the
splash screen from the documentation. It remains a requirement for
processing mouse and keyboard events.

=> Re-activate tst_QSplashScreen and test visibility in the constructor
test function.

Drive by:
- implement switch in event override
- factor out paint event handling in a function
- update documentation about calling processEvents() to enable mouse
handling.

Volker Hilsheimer 9ea9e2476d QMainWindow: don't crash when restored state is modified before applied
Amends 32edae5e26, after which we keep a
copy of the restored state if the state couldn't be applied yet. Since
making a copy of the entire state results in multiple copies of layout
item pointers, we might end up with dangling pointers if the layout
structure is modified while we keep the copy. This can happen if methods
such as tabifyDockWidgets or splitDockWidget get called; e.g. tabifying
dock widgets will destroy the layout items that were added for them.

Unfortunately, the layout items do not have a pointer back to the layout
they live in, and the items in the stored state might not yet live in a
layout anyway. So we cannot remove the items from their layout in a
QDockWidgetItem destructor implementation.

Instead, we have to forget the stored state. Add a helper function that
writes the stored state back to the actual state, and deletes the stored
state afterwards. Call this function when the layout might get modified
programmatically.

Add a test case that reproduces the crash without the fix, and passes
with the patch.

Axel Spoerl e6d85cf28b QDockWidget: Fix group unplugging
A floating dock widget could either be a single QDockWidget object,
or a QDockWidgetGroupWindow with a single QDockWidget child.
The former could be dropped on the latter. Dropping the latter on
the former caused a crash.

The existence of QDockWidgetGroupWindows with a single dock widget
child was accepted to be by design.
Previous fixes, such as  9ff40b59da,
attempted to wrap all single floating dock widgets in
QDockWidgetGroupWindows.

These attempts fell short, because of the manifold programmatic and
manual options to create a floating dock widget:
- drag a single dock widget out of a main window dock area
- drag a dock widget out of a tab bar on the main window
- drag a dock widget out of a floating tab
- call `QDockWidget::setFloating(true)` in any situation
- create a new QDockWidget, that floats from the beginning

Whenever a QDockWidgetGroupWindow with a single QDockWidget child
was hovered and/or dropped on a QDockWidget without a group window,
crashes or screen artifacts were observed. Previous fixes made them
occur less often.

QDockWidgetGroupWindow is not designed to hold a single QDockWidget
child. Such a state is inconsistent and may only exist, while a
QDockWidgetGroupWindow is constructed.

The reason why such invalid QDockWidgetGroupWindows started to exist,
is a bool trap: QDockWidgetPrivate::mouseMoveEvent() starts a drag
operation, when a dock widget is moved by mouse.
It called startDrag() with no argument, which defaulted to
startDrag(true) and caused a group drag.

This assumption is
*correct*, when a tabbed group of dock widgets is dragged out of the
main dock as a whole, to become floating tabs.
*wrong*, when a single dock widget is dragged out of a docked group,
to become a single floating dock widget.

In the second case, the dock widget was wrapped in a new, floating,
invisible QDockWidgetGroupWindow. Looking like a single, floating dock
widget, the group window caused a crash, when attempted to be dropped
on another dock widget.

This patch eliminates all cases, where a QDockWidgetGroupWindow with
a single QDockWidget is created:
(1) Implement QDockWidgetPrivate::isTabbed().
This enables mouseMoveEvent to determine, whether the move relates to a
group of tabbed dock widgets, or to a single dock widget.
startDrag() can therefore be called with the right argument. It will no
longer create a QDockWidgetGroupWindow with a single QDockWidget child.

(2) Change QMainWindowTabBar::mouseReleaseEvent
When a dock widget was dragged out of a tab bar and became a single,
floating dock widget, it was still parented to the group window.
That is wrong, because it has no more relationship with that group
window.
=> Reparent it to the main window, just like any other single floating
dock widget. That enables QDockWidgetGroupWindow to detect, that the
2nd last child has gone and no more group window is needed (see next
point).

(3) React to reparenting, closing and deleting
If the second last dock widget in a floating tab gets closed (manually
or programmatically), reparented or deleted, also unplug the last one
and remove the group window.

(4) Amend 9ff40b59da
Remove the code path where a QDockWidgetGroupWindow with a single
QDockWidget child was created 'just in case', to make it compatible
others, created by (1), (2) or (3).

(5) Change QMainWindowLayout::hover()
When the hover ends without a successful drop and a temporary group
window with a single dock widget child has been created, remove the
group window.

The patch fixes smaller inconsistencies, which have not become visible
due to assertions and crashes earlier in the chain.

The patch finally extends tst_QDockWidget, to cover all 4 cases.

- Creation of floating tabs
The creation of floating tabs is extracted from floatingTabs() to
the helper function createFloatingTabs(). In addition to creating
floating tabs, the helper verifies that dragging a dock widget out
of the main window doesn't accidently wrap it in a group window.
This covers case (1).

- tst_QDockWidget::floatingTabs()
The test function verifies now, that both test dock widgets have the
same path before plugging them together and after unplugging them from
the floating tab. This covers case(4).

- tst_QDockwidget::deleteFloatingTabWithSingleDockWidget()
This test function is added, to cover cases (2) and (3).

- tst_QDockWidget::hoverWithoutDrop()
This test function hovers two floating dock widgets hover each other,
and returns the moved dock widget to its origin before releasing the
mouse. This covers case(5).

This fixes a lot of long standing bugs, making the author of this patch
modestly happy :-)

Axel Spoerl 0b10b7476c Refactor tst_QDockWidget::closeAndDelete()
The test function was temporarily blacklisted on Ubuntu, but also
failing on other Linux platforms (e.g. openSuSE).

It tested, whether closing all dock widgets and the main window, would
close the application as well. It used one single shot timer, to close
the windows and later one to check, whether the application was shut
down.

While that mechanism must work in an application environment, it is not
guaranteed to work in testlib. More specifically, I could happen that
the XCB / glib event loop continued to spin and wait for events.

=> Check the signal QGuiApplication::lastWindowClosed() instead. If the
signal is fired, it is proven that all windows have been closed and
the application would quit in a production environment.

The underlying test case was: Application didn't quit with the last
dock widget closed, because there was a dangling
QDockWidgetGroupWindow.

=> finally: Clean up BLACKLIST

Tor Arne Vestbø d44413d526 Explicitly focus automatic default button in QDialogButtonBox inside dialog
QDialogButtonBox has logic to automatically resolve a default button,
in case one is not already set via QPushButton directly, or via e.g.
QMessageBox::setDefaultButton().

Unfortunately, this default button can in some cases be overridden by
the first button in the dialog button box. The reason this happens
is that the first button is the focus proxy of the button box, so
when the button box gains focus, it will transfer it to the first
button. And since QPushButtons inside a QDialog have their autoDefault
property set to true by default, this focus transfer will also reset
the default button to the focused button.

This arbitrarily happens for any role that happens to be earlier in
the QDialogButtonBox::ButtonLayout than the AcceptRole, and can be
very confusing for the user, so we try to avoid the situation by
explicitly setting the automatic default button as the focus
widget of the button box, unless one is set already.

This is also what QMessageBox::setDefaultButton() does internally.

The only case we're not covering is when the user sets a push button
as default via QPushButton::setDefault(), but we conservatively
assume that the user then also calls setFocus() on the button.

Tor Arne Vestbø cd4000a97d Use QtGui to match QWindow based shortcuts, even when QApplication is used
If a QShortcut is registered with a QWindow as its parent, but QApplication
is used, we end up in QApplicationPrivate::createShortcutPrivate(), and
create a QtWidgetsShortcutPrivate that implements shortcut context matching
via qWidgetShortcutContextMatcher.

The problem is that qWidgetShortcutContextMatcher expects the windows
to be QWidgetWindows, which meant that plain QWindow based shortcuts
would always fail.

This can happen for example if a QApplication is used in Qt Quick
to provide dialog fallbacks, but QShortcuts are otherwise used
with plain QWindows, or QQuickWindows e.g.

We now defer the check of whether there's an active (widget) window,
and fall back to QtGui's simpleContextMatcher in case we don't find
a QWidget, QAction, or QGraphicsWidget shortcut owner to handle
the matching for.

Note: We don't support shortcut matching for QAction in QtGui,
but this is left for another day. There is also a discrepancy
between how QtGui and QtWidgets handles Qt::ApplicationShortcut.
The former will treat it as a match even if there is no active
QWindow, while the latter requires that there's an active widget
window.

Axel Spoerl 92d837e684 QDockWidget: Do not propagate title from a closed dock widget
When a dock widget is closed while floating, it still reports being
floating even though the QWidget::windowHandle()->isVisible() returns
false. This is documented behavior and will not be changed.

c153066baa relied on the isFloating() to
return false, if the dock widget is closed. When the window title was
changed by setWindowTitle(), the change was overridden by reading the
old value from the window handle.

=> Amend the patch and add a windowHandle()->isVisible() as a condition.

In c153066baa, an autotest for the title
propagation (QTBUG-113591) was added to floatingTabs().

=> Harden the setWindowTitle() test function. Move the tests related to
QTBUG-113591 and QTBUG-117764 to this function.

Wladimir Leuschner cf6bccbcf5 Ensure stable sort in QListWidget
QlistWidgets with sorting enabled do not sort stable. A re-sort is
triggered when any Qt::ItemDataRole is changed and not only when
Qt::DisplayRole is changed. Due to an unstable optimization, the changed
element gets inserted at the beginning of their respective "equivalence
group".

This patch disables the optimization and ensures stable sorting
with std::stable_sort. Sorting is only performed, if the subset of
changed items in the range [begin, end] is not already sorted in the
whole list. For this purpose, it is assumed that the list has already been sorted before begin and after end. This assumption minimizes the subset to check.

Limits / side effect:
The patch focuses on the most common use case, which is a single item being changed. Replacing the optimization by std:stable_sort can potentially slow down the sorting performance of large data sets.

editor, so the delegate will get the focusOut event (and other

written back to the model.
In the case where the editor of a delegate (QAbstractItemDelegate)
is a QSpinBox with keyboardTracking set to false, the value of
the spinbox won't be updated while typing, but only when the
spinbox's text edit focus is lost. In this case, the delegate's
commitData will be emitted before the spinbox has had a chance
to update the value in its handling of the focusOut event.
To fix, make sure to update the value before the data is
committed to the model in the delegate's tryFixup method.
