Instead of having each platform plugin deal with application termination
in their own weird ways, we now have a QPA API to signal that the system
requested the application to terminate.
On the QGuiApplication side this results in a Quit event being sent to
the application, which triggers the default behavior of closing all app
windows, and then finally calling QCoreApplication::quit().
The quit event replaces the misuse of a close event being sent to the
application. Close events are documented as being sent to windows.
The close events that are sent to individual windows as part of the
quit process can be ignored. This will skip the final quit() of
the application, and also inform the platform that the quit was
not accepted, in case that should be propagated further.
In the future the logic for closing windows should be unified
between the various approaches in closeAllWindows, shouldQuit,
and friends.

The functions in QPlatformIntegration have been left in, but deprecated

... instead of using a hack of directly accessing QGuiApplication
members.
The current QPA API was bad for two reasons:
1) It expects platform plugin authors to know about
internals of Qt Gui, particularly that QGuiApplication
uses QGuiApplication::{mouseButtons,keyboardModifiers}
to construct QDragMoveEvent and QDropEvent events. Which
results in the second reason why this is bad.
2) Platform plugins should not directly access member
variables of QGuiApplication, just to make sure that
QDragMoveEvent and QDropEvent events contain correct state.
Platform plugins should instead use QWindowSystemInterface
to communicate with Qt Gui (which is also the solution here).
The solution is to extend QWindowSystemInterface::handle{Drag,Drop}
to require mouse/keyboard state. We already do this for
some of the other methods, so it is nothing extraordinary.
This type of interface is also _required_ to support
drag-n-drops from other processes. We can't use
QGuiApplication::{mouseButtons,keyboardModifiers} when the
drag originates from another process, instead we need to
query mouse/keyboard state from the system.
This patch fixes drag-n-drops from others processes on XCB

... and deprecate QWSI APIs that accepts mouse event without mouse button/
type data.
In the early days of Qt5 it was decided to centralize mouse button/type
handling in QGuiApplication (because of limitation of some now unknown
platform). This has proven to be problematic as mouse handling details
differ across platforms (e.g on X11 we do not receive mouse release event
when closing popup windows or ordinary windows that are closed from the
mouse press event). Instead of hacking around platform specific behaviors
in Qt Gui, we should move this task back to platform plugins (similar to
how this was done in Qt4 with native APIs sending mouse details directly
to QApplication). There are even cases where it simply is not possible
to deduce (from QGuiApplication) which button caused the event (e.g. when
more than one button is involved and some event goes missing). Besisdes,
throwing away information which is already available at QPA level (for free)
and trying to deduce it again at Qt Gui level seems impractical, fagile
(as probably noticed by people fixing all the unexpected issues) and adds
unnecessary complexity.
Note:
Removing the deprecated QWSI APIs from offscreen plugin depends on fixing
autotests that rely on QOffscreenCursor::setPos() logic.
For the convenience of testing use QT_QPA_DISABLE_ENHANCED_MOUSE to restore
to the old code path where QGuiApplication does the mouse state deducing.
Other platforms have similar issues. I do not have all supported platform
available on my desk, so other platform maintainers will need to take care
of porting those platforms to the new APIs. And mainly, I don't want to deal
with all the hacks that other platforms have added to workaround this broken
mouse logic.
In Qt6 we need to remove deprecated code path from QGuiApplication.
This patch:
- Extends QWindowSystemInterfacePrivate::MouseEvent ctor with QEvent::Type
and Qt::MouseButton. We use this extra data when processing mouse events in
QGuiApplication. This actually is similar to KeyEvent, where we do pass the
type (press or release) to QtGui.
- Refactors QGuiApplicationPrivate::processMouseEvent and qtestlib to use
the new APIs.

In a properly functioning code, g_main_context_iteration is expected
to block until any event source becomes ready to dispatch an event
(or interrupt occurs). Qt provides several custom event sources to
the Glib event loop. The bug (busy loop) was caused by faulty event
source implementation when QEventLoop::ExcludeUserInputEvents is set.
As long as the window system's event queue was not empty, we signaled
to the event dispatcher that there is an event ready to be dispatched.
This results in the dispatcher calling the relevant dispatch function
(which does handle the ExcludeUserInputEvents flag correctly). As we
do not dispatch user events, the window system's event queue never
becomes empty and we enter a busy loop (CPU running at 100%) where we
signal that we have events to dispatch, but we actually do not dispatch
them and g_main_context_iteration never gets to block.
This busy loop can cause blocking GTK functions such as gtk_dialog_run()
never return.

The contact patch of a finger on a touchscreen tends to be roughly
elliptical. If we model it as a QRectF, it's not clear whether the
ellipse should be considered to be inscribed in the rectangle and then
rotated, or whether the rectangle represents the outer bounds of the
rotated ellipse. In practice, since most touchscreens can't measure
rotation, it is effectively the latter. But modeling it that way means
information is lost if the touchscreen can measure rotation: you can
determine the bounds of a rotated ellipse, but you cannot derive the
rotated ellipse from its bounds. So it's better to model the axes
of the ellipse explicitly. This has the added benefit of saving a
little storage space: we replace 3 QRectF instances, whose width
and height will normally be the same, with 3 positions (bringing the
total to 12 QPointF's) and one set of axes. Further, most applications
only care about the center of each contact patch, so it's better to
store that explicitly instead of calculating QRectF::center() repeatedly.
In the past there may have been an assumption that the width of the rect is
the same as the horizontalDiameter of the ellipse, so the rect could be
considered to be rotated, and the ellipse to be inscribed. But in
d0b1c646b4 and
40e4949674 the point was made that the rect
is actually the bounding box of the rotated ellipse.

We introduce processWindowSystemEvent() in QWindowSystemInterfacePrivate

This is then coupled with a templated version of handleWindowSystemEvent()

that's used. The default specialization will decide based on the state
set by setSynchronousWindowSystemEvents(), as before.
This allows templated versions of handleMouseEvent, handleKeyEvent, etc

get away from using setSynchronousWindowSystemEvents() as a temporary
switch to synchronous mode.
The templates are defined in the QWindowSystemInterface source file,
with explicit instantiations of the three supported modes of delivery,
as having the definition in the header file would both require inlining,
as well as qwindowsysteminterface.h having access to the private parts
of QWindowSystemInterfacePrivate for the template function bodies.
