Amend 3e59a88e89, which incorrectly used
isHidden() to test whether the scrollbar is visible or not.
QWidget::isHidden() is only true for child widgets that are explicitly
hidden (or created for visible parents, which the scrollbars are not).
Since the scrollbars are children of a container that is hidden and
shown, isHidden always returns false.
Instead, use QWidget::isVisibleTo, passing the scroll area, as that
tells us if the scrollbar's visibility is relevant for the layout of the
scroll area.
Add a test case for QAbstractScrollArea, verifying that the scrollbar's
size is correctly taken into account when calculating the size hint.
This change revealed an instability in the tests introduced in the
earlier commit: the layout process is asynchronous, requiring event
processing to update the visibility of the scrollbars. Add a call to
processEvents before storing the reference size hint. Also, explicitly
set a style that doesn't use transient scrollbars as otherwise we cannot
control when the scrollbars are shown.
The chagne also revealed an inaccuracy in the QListView test, which
only passed because the width of the vertical scrollbar was included.
We cannot use font metrics results to compare expected width, as the
item delegate's text rendering uses text layouts.

When a table view adds its first row, QHeaderView::initializeSections()
is called. It initializes the vertical header view with the number of
added sections. Subsequently QHeaderView::sectionsInserted() is called
with the same amount of newly added rows/sections.
That leads to the initial amount of sections being 2x the number of
rows added in the first go. In other words, the table view will display
at least one row more than the underlying table model has.
This patch adds an OR condition to the early return check at the
beginning of QHeaderView::sectionsInserted(). The method returns early
if the number of sections equals the number of respective sections
(rows in this case) in the model.
An autotest is added in tst_QTableView::rowsInVerticalHeader().

Some item views, such as QListView in icon mode, implement a selection
rectangle with which the user can "lasso" items. So far, dragging that
rectangle did not trigger auto scroll, so unless an item near the edge
was selected, the user had to stop the lassoing and scroll manually to
reach more items.
Since QAbtractItemView implements auto scrolling for drag'n'drop, we can
use that mechanism also when the selection rectangle is dragged. This
requires some modifications:
We need to make sure that scrolling the view during a drag-selection
generates mouse move events so that the selection is extended and the
rectangle is updated in subclasses.
And we need to stop using QCursor::pos to get the position of the mouse
pointer, as this makes the auto-scrolling untestable. Instead, record
the mouse position last seen during a mouseMove or dragMoveEvent in
content-coordinates (identical to pressedPosition).

Item views can open an editor widget on the first key press, and need to
take special care not to break input methods. The initial key press
starts compositing by the system input method, which is then interrupted
by the focus transfer to the editor.
To solve this problem, the widget needs to keep focus while the initial
composition is ongoing, and only transfer focus to the editor once the
composition is either accepted or cancelled by the user. Add a state flag
that is set during this initial preedit phase.
During this initial composition, the item view will receive all input
method events, and needs to forward these to the open, but not yet focused
editor for the user to get the correct visual feedback during the preedit
phase. The item view also needs to report to input method queries on
behalf of the editor to make sure that the IM UI is correctly positioned
without covering the user input.
Implement a test that simulates the sequences through synthesized
QInputMethodEvents; we can't simulate the entire system input stack.

After the last row is moved, 0 will be returned when obtaining
row and column data. At this time, QListView::doitemslayout will
not call d->doitemslayout, so the QBspTree data structure will
not be cleaned up, leaving a stale tree structure behind. This
will trigger an assert during paintEvent handling if QListView is
set to IconMode
In QListView::ListMode the test for a valid model index doesn't
use an assert.
Call QListViewPrivate::clear explicitly if the column count is 0
so that the QBspTree and other data structures are cleared.
Add a test case that simulates this scenario by implementing a
model that returns a 0 column count for an index after the model
structure was changed through a move of rows.
