Laszlo Agocs 68a4c5da9a Compose render-to-texture widgets through QRhi
QPlatformTextureList holds a QRhiTexture instead of GLuint. A
QPlatformBackingStore now optionally can own a QRhi and a
QRhiSwapChain for the associated window.  Non-GL rendering must use
this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still
rely on resource sharing between contexts. A widget tells that it
wants QRhi and the desired configuration in a new virtual function in
QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is
evaluated (among a top-level's all children) upon create() before
creating the repaint manager and the QWidgetWindow.

In QOpenGLWidget what do request is obvious: it will request an
OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget)
will be more interesting: it needs to honor the standard Qt Quick
env.vars. and QQuickWindow APIs (or, in whatever way the user
configured the QRhiWidget), and so will set up the config struct
accordingly.

In addition, the rhiconfig and surface type is (re)evaluated when
(re)parenting a widget to a new tlw. If needed, this will now trigger
a destroy - create on the tlw. This should be be safe to do in
setParent. When multiple child widgets report an enabled rhiconfig,
the first one (the first child encountered) wins. So e.g. attempting
to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same
top-level window will fail one of the widgets (it likely won't
render).

RasterGLSurface is no longer used by widgets. Rather, the appropriate
surface type is chosen.

The rhi support in the backingstore is usable without widgets as well.
To make rhiFlush() functional, one needs to call setRhiConfig() after
creating the QBackingStore. (like QWidget does to top-level windows)

Most of the QT_NO_OPENGL ifdefs are eliminated all over the place.
Everything with QRhi is unconditional code at compile time, except the
actual initialization.

Having to plumb the widget tlw's shareContext (or, now, the QRhi)
through QWindowPrivate is no longer needed.  The old approach does not
scale: to implement composeAndFlush (now rhiFlush) we need more than
just a QRhi object, and this way we no longer pollute everything
starting from the widget level (QWidget's topextra -> QWidgetWindow ->
QWindowPrivate) just to send data around.

The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split
is all gone. Instead, there is a QBackingStoreDefaultCompositor in
QtGui which is what the default implementations of composeAndFlush and
toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs
should continue working mostly as-is, apart from adapting to the
texture list changes and getting the native OpenGL texture id out of
the QRhiTexture)

As QQuickWidget is way too complicated to just port as-is, an rhi
manual test (rhiwidget) is introduced as a first step, in ordewr to
exercise a simple, custom render-to-texture widget that does something
using a (not necessarily OpenGL-backed) QRhi and acts as fully
functional QWidget (modeled after QOpenGLWidget). This can also form
the foundation of a potential future QRhiWidget.

It is also possible to force the QRhi-based flushing always,
regardless of the presence of render-to-texture widgets. To exercise
this, set the env.var. QT_WIDGETS_RHI=1. This picks a
platform-specific default, and can be overridden with
QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be
extended to query the platform plugin as well to check if the platform
plugin prefers to always do flushes with a 3D API.

QOpenGLWidget should work like before from the user's perspective, while
internally it has to do some things differently to play nice and prevent
regressions with the new rendering architecture. To exercise this
better, the qopenglwidget example gets a new tab-based view (that could
perhaps replace the example's main window later on?). The openglwidget
manual test is made compatible with Qt 6, and gets a counterpart in form
of the dockedopenglwidget manual test, which is a modified version of
the cube example that features dock widgets. This is relevant in
particular because render-to-texture widgets within a QDockWidget has
its own specific quirks, with logic taking this into account, hence
testing is essential.

For existing applications there are two important consequences with
this patch in place:

- Once the rhi-based composition is enabled, it stays active for the
lifetime of the top-level window.

- Dynamically creating and parenting the first render-to-texture
widget to an already created tlw will destroy and recreate the tlw
(and the underlying window). The visible effects of this depend on the
platform.  (e.g. the window may disappear and reappear on some,
whereas with other windowing systems it is not noticeable at all -
this is not really different from similar situtions with reparenting
or when moving windows between screens, so should be acceptable in
practice)

- On iOS raster windows are flushed with Metal (and rhi) from now on
(previously this was through OpenGL by making flush() call
composeAndFlush().

Giuseppe D'Angelo 9ea1f0f8b9 Fix qobject_cast on partially destroyed QWidget/QWindow
QWidget and QWindow use bits in QObjectPrivate to provide for a couple
of shortcuts -- one in qobject_cast, and another in the isWidgetType() /
isWindowType() functions in QObject. These can be optimized by simply
looking at the bits, without actually doing more expensive runtime
casts.

These bits were set on construction, but not unset on destruction.  The
result was for instance that destroying a QWidget would report that the
object was still a QWidget when ~QObject was reached.

Fix this

1) by setting the bits only when QWidget / QWindow constructors start;

2) by resetting the bits once ~QWidget / ~QWindow are completed.
Technically speaking this is not 100% correct in the presence of data
members, but luckily those classes don't have any.

Amend an existing test for QWidget (whose comment said exactly the
opposite of what the test actually did) and add a test for QWindow.

Some other code was wrongly relying on isWidgetType() returning true
for destroyed QWidgets; amend it as needed.

[ChangeLog][QtCore][QObject] Using qobject_cast on partially constructed
or destroyed QWidget/QWindow instances now yields correct results.
Similarly, using the convenience isWidgetType() / isWindowType()
functions now correctly return false on such instances. Before,
qobject_cast (and the convenience functions) would erroneously report
that a given object was a QWidget (resp. QWindow) even during that
object's construction (before QObject's constructor had completed) or
destruction (after QWidget's (resp. QWindow's) destructors had been
completed). This was semantically wrong and inconsistent with other ways
of gathering runtime type information regarding such an object (e.g.
dynamic_cast, obj->metaObject()->className() and so on).

Richard Moe Gustavsen 7c6e4af483 QWidget: always handle IM queries
A widget (e.g QLineEdit) will set WA_InputMethodEnabled to
false if it's read-only. But it can still contain selected
text (e.g from a mouse drag). In many cases, it therefore
makes sense to be able to query the focus object for what
that selection is, e.g to be able to show selection handles
from the QPA plugin (iOS/Android).

Therefore, remove the check if a widget has WA_InputMethodEnabled,
and always process the query. The caller can always check this
flag himself (or Qt::ImEnabled) before sending the query, if needed.

Tor Arne Vestbø 2f6d572dad macOS: Compute NSWindow background color without checking styleMask
The check for styleMask == NSWindowStyleMaskBorderless to decide whether
to clear the NSWindow background was broken, as NSWindowStyleMaskBorderless
has the value 0, but is only supposed to be compared to its companion
NSWindowStyleMaskTitled (with value 1). A window can perfectly well be
NSWindowStyleMaskBorderless and NSWindowStyleMaskMiniaturizable e.g.,
so by comparing directly to NSWindowStyleMaskBorderless instead of
masking to the first bit first we ended up making miniaturizable
windows non-translucent.

We now check the Qt::FramelessWindowHint directly, and also whether
the window is opaque. Ideally we'd have QWindow flags that could
plumb WA_NoSystemBackground from Qt Widgets, as well as a background
color property on QWindow to control the system background, but
in the meantime we'll have to use the FramelessWindowHint heuristic.

The QWidget docs have been updated to reflect this.

We want to close the window, end full screen mode on macOS, and free

closes the platform window, triggering a closeEvent to QWidgetWindow,
which then calls QWidgetPrivate::close_helper.

This way, closing a window via QWidget::close, QWindow::close, or
interactively by the user are all equivalent.

The QCloseEvent generated by the widget needs to be spontaneous for
window-system generated events (i.e. the user clicked the close button),
and non-spontaneous if the window closes because of a call to
QWindow::close. To keep track of whether the event originated in an
explicit call to QWindow::close, add a boolean to the QWindowPrivate.

Laszlo Agocs e6a969954a Do not alter a widget's backing window's format once created
Changing anything on a QWindow's QSurfaceFormat has zero and null
effects once the underlying native window has been created. Letting
QWidget update the format is wrong in this case, because we always
expect that the value returned from QWindow::format() reflects
reality.

(reality being the settings with which the underlying native resource
was created, which is typically frozen after QWindow::create(), not
the state of some QWidget attribute. There are certain exceptions to
this, such as when preparing to recreate the underlying native window,
in which case one will want to update all relevant fields of the
format based on the current values of the widget attributes, which is
exactly what QWidgetPrivate::create() implements, and that's good.)

Such a mismatch can have fatal consequences when OpenGL and friends
are involved, but this always depends heavily on the platform and
windowing system. For example, claiming that the alpha buffer size is
0 when the native window was created with 8, or vice versa, can break
OpenGL-related code (both in Qt itself and in applications), that
tries to create a QOpengGLContext configured based on what
QWindow::format() returns. If that format describes settings that are
incompatible with the actual underlying native window, we end up with
the classic Invalid pixel format, EGL_BAD_MATCH, and alike errors.

This is exactly what is happening when a QOpenGLWidget (or
QQuickWidget) is placed in a QDockWidget where one of the ancestors is
forced to native (winId() was called or WA_NativeWindow was set). When
undocking, various code paths in QWidget will try to update the opaque
flag of the widget, which in turn calls updateIsTranslucent. Now, if
this function unconditionally changes the alphaBufferSize in the
QWindow's QSurfaceFormat (even though this is completely futile to do,
it has no visible effect in practice), we get the problem described
above: rendering breaking down due to OpenGL contexts created with a
pixel format incompatible with the native window.

Prevent all this by not touching the format once the QWindow has a
QPlatformWindow. This is the right thing to do, regardless of the bug
in question: a window's (or context's or any other native resource
wrapping class's) format must describe the underlying native resource
and must never deviate, unless we are preparing to create a new native
resource underneath.

When it comes to the autotest, this changes the test added in
555661b625c40f21a6a3e4c73e928a6e8a46db20: the autotest logic is
inverted because what we should test for is that the QSurfaceFormat
stays untouched once the application makes a - futile - attribute
change on the widget.

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.

Tor Arne Vestbø 7d5ba1c17e widgets: Don't report new focus object during clearFocus() unless needed
We do not unconditionally clear focus_child like the existing comment
said. We only do it if the focus_child was the widget that is clearing
focus. So in many cases we'll end up with the same focus object as
before. We can not report that as a focusObjectChanged to the window,
as that will potentially trigger a reset or cancel of the current
input method for the (unchanged) focus object.

QPlatformNativeInterface on a QPA level. Using 'native' for the user
facing APIs also distinguishes them from the 'platform' backend layer
in QPA and elsewhere.

Volker Hilsheimer 0f39cfae93 Change QWidget::enterEvent signature to take a QEnterEvent
This is a source incompatible change for widget implementors.
Leaving the old enterEvent as a virtual overload is problematic due to
shadowing. Best to make a clean cut, widget reimplementors will get a compile
time warning if they mark their override as such, or if they try to call the
parent class implementation.

Addresses ### Qt 6 comment.

[ChangeLog][QtWidgets][QWidget] The virtual enterEvent handler now receives
a QEnterEvent, which contains information about mouse position and button
states, rather than a plain QEvent.

Having three methods with the same name doing different things is
unnecessarily confusing, so follow the standard naming convention in
Qt and call the getter of the resolve mask resolveMask, and the setter
setResolveMask. These methods were all documented as internal.

The publicly documented resolve() method that merges two fonts and
palettes based on the respective masks remains as it is, even though
'merge' would perhaps be a better name.
