Ivan Solovev 00505ed2b5 Widgets: fix setTabOrder for QAbstractSpinBox-like widgets
setTabOrder was not considering the case, when a child widget has
its focus proxy set to its parent widget. This happens, for example,
for the QLineEdit that is nested inside the QAbstractSpinBox.
For such cases the lastFocusChild was calculated incorrectly, and, as
a result, such child widgets were not correctly positioned in the
focus chain. This could lead to an error while backtabbing.

Here is a brief example. Suppose we have 3 widgets arranged like this:

auto spinBoxOne = new QDoubleSpinBox;
auto spinBoxTwo = new QDoubleSpinBox;
auto button = new QPushButton;

Then the default widget focus order is:
- spinBoxOne
- lineedit (from spinBoxOne)
- spinBoxTwo
- lineedit (from spinBoxTwo)
- button

Before this commit setting the explicit tab order changed the focus
order in the following way:

QWidget::setTabOrder(spinBoxOne, spinBoxTwo);
QWidget::setTabOrder(spinBoxTwo, button);

- spinBoxOne
- spinBoxTwo
- button
- lineedit (from spinBoxOne)
- lineedit (from spinBoxTwo)

In this case, backtabbing from spinBoxOne actually leads us to
lineedit (from spinBoxTwo), which refers to spinBoxTwo.
And so we're stuck in a loop.

This commit fixes the issue by handling such special case, and
preserving correct focus order.

Note: the actual unit-test in this patch uses QLineEdit instead of
QPushButton, because one can't tab to buttons on macOS by default.
However the general idea is the same.

Pick-to: 6.0 5.15
Fixes: QTBUG-81097

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
