* QWidgetWindow: Don't meddle with WA_WState_{Hidden/ExplicitShowHide}Tor Arne Vestbø2024-02-121-14/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ccd3bf0871b81dfc09bb469b161f32dfb47ee53e we introduced code that would ensure that our call to QWidgetPrivate::setVisible() from QWidgetWindow would not result in WA_WState_Hidden being set. This code was later modified in 51300566ffe2ece2455e1d0479a556c5dbb3bb8e to apply to widgets that were explicitly shown/hidden. Unfortunately, the reset of the Hidden and ExplicitShowHide attributes would in some cases result in the widget having only ExplicitShowHide after being hidden, which is an invalid state. It also resulted in the widget having both Visible, Hidden, and ExplicitShowHide, if first being hidden via QWidget, and then shown via QWindow, which in turn prevented the widget from being hidden via QWidget::hide(). As we no longer rely on the adjustments to Hidden/ExplicitShowHide to fix QTBUG-73021, we can remove the entire logic. Any setVisible call to QWidgetWindow will either come from outside, in which case we should respect that and set Visible/Hidden via QWidgetPrivate, or the setVisible call is a result of QWidget itself (or its parent) showing the QWidgetWindow, in which case the QWidget visible state is already up to date and we skip the QWidgetPrivate::setVisible call.

* Don't set ExplicitShowHide on children when showing parent widgetTor Arne Vestbø2024-02-011-22/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As a result of using QWidget::setVisible to show the child widgets we would end up also setting ExplicitShowHide. This is not in line with the intent of ExplicitShowHide, which is to flag a widget as explicitly shown/hidden by the developer, which in turn prevents Qt Widgets from toggling WState_Hidden when the widget is reparented. By using QWidgetPrivate::setVisible instead, we can show the child without setting ExplicitShowHide. As side effect of this is that we no longer reset WA_WState_Hidden from QWidgetWindowPrivate::setVisible(). This is an issue when the setVisible call comes as a result of destroying the QWidgetWindow, as that is an implicit hide, and should not result in the widget having WA_WState_Hidden. QWidget handles this case in hideChildren by not calling QWidgetPrivate::setVisible -- instead doing its own reset of WA_WState_Visible. We don't want to untangle this just yet, so as a workaround we detect that the widget is already !isVisible(), thanks to hideChildren having hidden it, and then skip the call to QWidgetPrivate::setVisible that results from QWindow::destroy().

* QWidget: Clean up state that depends on QWindow from ~QWidgetWindow()Tor Arne Vestbø2024-01-231-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were assuming that QWidget was in full control of QWidgetWindow destruction, via deleteTLSysExtra(), and that we could limit any cleanups to that function. But in some situations QWidgetWindow is destructed from other code paths, in which case we were left with dangling pointers to the QWidgetWindow in both QTLWExtra, as well as the backingstore. This can happen if there's a child widget hierarchy where there is not a 1:1 mapping between QWidgets and QWindows, for example if the window attribute WA_DontCreateNativeAncestors has been set. In this situation our normal recursion into children in QWidget::destroy() stops at the first widget without a window handle. When we then delete the top level QWindow, the QWindow destructor will delete any child QWindows, which includes our leaf QWidgetWindow. We should probably fix up QWidget::destroy to continue looking for children, even if we don't destroy the current child. But independently of that we should make sure the QWidgetWindow cleans up when it's being deleted, regardless of how it ended up there. There's further room to clean up the deleteTLSysExtra() function and friends, but that's been left for a later time.

* Sync QWindow visible state during QWidget destructionTor Arne Vestbø2023-12-201-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Introduce events for Window device pixel ratio changesDavid Edmundson2023-02-131-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | There is a mix between screen device pixel ratio. Currently we store the property on a per-window basis, but the change notifications are still on a per screen basis which can fall apart on edge cases. On wayland we are getting per window DPR changes without as useful screen change events so it's important to fix. It also has potential to clean up the Windows backend in the future where the backend is currently papering over the two concepts. This patch introduces two new events: A QWindowSystemInterface to trigger a window DPR change independently of a screen change. An event to notify windows the new DPR rather than needing to track signals on the screen. This happens either when the window dpr changes or implicitly through a screen change. This can deprecate an existing event ScreenChangeInternal so the value is reused and renamed for clarity.

* Harden drag and drop handling in widget windowLaszlo Agocs2022-07-011-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | User code in an event handler can do arbitrary things, including operations that lead to destroying the QWidgetWindow. An example is what the autotest does: reparenting the top-level widget to under another top-level upon the drop. Internally this leads to destroying the drop target's QWidgetWindow as the widget is now a child, not a top-level. In fact some of the existing drag and drop handling code seems to be prepared to handle the case of having the drag target widget destroyed in the user's event handler during a drag-move. But none of it is prepared for having the QWidgetWindow destroyed upon returning from forwardEvent(). The associated bug report has the same root cause, it is just popping up now via the new 6.4 behavior: adding a QOpenGLWidget to a widget hierarchy upon a drop leads to getting a new QWidgetWindow (if the window only had regular raster widgets before). To solve this, avoid touching members on 'this' after the forwardEvent(). It looks like the handlers for mouse events follow this pattern already, no member data is touched after forwarding events (not sure if that is intentional or just incidental but it is the safe solution, even if this is not feasible everywhere, but ideally input events should take this into account).

* Compose render-to-texture widgets through QRhiLaszlo Agocs2022-03-111-16/+6

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().

The two paths now share the same logic for determining if there are any remaining windows. The docs have been updated to reflect the original intent of the logic, dealing only with primary windows (top levels without a transient parent). This was how both the original code paths implemented their logic. For historical reasons the Qt::WA_QuitOnClose attribute is closely tied to the lastWindowClosed signal, and isn't merely limited to controlling whether we try an automatic quit when the last window closes. For now this behavior has been kept, but the docs have been updated to clarify how the attribute is handled in practice.

* Track grab state in QPointingDevicePrivate::activePointsShawn Rutledge2020-09-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QQuickEventPoint instances were very long-lived and got reused from one event to the next. That was initially done because they were "heavy" QObjects; but it also became useful to store state in them between events. But this is in conflict with the ubiquitous event replay code that assumes it's OK to hold an event instance (especially a QMouseEvent) for any length of time, and then send it to some widget, item or window. Clearly QEventPoints must be stored in the QPointerEvent, if we are to avoid the need for workarounds to keep such old code working. And now they have d-pointers, so copying is cheap. But replay code will need to detach() their QEventPoints now. QEventPoint is useful as an object to hold state, but we now store the truly persistent state separately in an EventPointData struct, in QPointingDevicePrivate::activePoints. Incoming events merely update the persistent points, then we deliver those instead. Thus when event handler code modifies state, it will be remembered even when the delivery is done and the QPA event is destroyed. This gets us a step closer to supporting multiple simultaneous mice. Within pointer events, the points are moved up to QPointerEvent itself: QList<QEventPoint> m_points; This means pointCount(), point(int i) and points() can be non-virtual. However in any QSinglePointEvent, the list only contains one point. We hope that pessimization is worthwhile for the sake of removing virtual functions, simplifying code in event classes themselves, and enabling the use of the range-for loop over points() with any kind of QPointerEvent, not just QTouchEvent. points() is a nicer API for the sake of range-for looping; but point() is more suited to being non-const. In QML it's expected to be OK to emit a signal with a QPointerEvent by value: that will involve copying the event. But QEventPoint instances are explicitly shared, so calling setAccepted() modifies the instance in activePoints (EventPointData.eventPoint.d->accept); and the grabbers are stored separately and thus preserved between events. In code such as MouseArea { onPressed: mouse.accepted = false } we can either continue to emit the QQuickMouseEvent wrapper or perhaps QEvent::setAccepted() could become virtual and set the eventpoint's accepted flag instead, so that it will survive after the event copy that QML sees is discarded. The grabChanged() signal is useful to keep QQuickWindow informed when items or handlers change exclusive or passive grabbers. When a release happens at a different location than the last move event, Qt synthesizes an additional move. But it would be "boring" if QEventPoint::lastXPosition() accessors in any released eventpoint always returned the same as the current QEventPoint::xPosition()s just because of that; and it would mean that the velocity() must always be zero on release, which would make it hard to use the final velocity to drive an animation. So now we expect the lastPositions to be different than current positions in a released eventpoint. De-inline some functions whose implementations might be subject to change later on. Improve documentation. Since we have an accessor for pressTimestamp(), we might as well add one for timestamp() too. That way users get enough information to calculate instantaneous velocity, since the plan is for velocity() to be somewhat smoothed.

* Introduce QWindow::paintEvent with QPA plumbingTor Arne Vestbø2020-08-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The explicit paint event on QtGui and QPA level allows us to untangle the expose event, which today has at least 3 different meanings. It also allows us to follow the platform more closely in its semantics of when painting can happen. On some platforms a paint can come in before a window is exposed, e.g. to prepare the first frame. On others a paint can come in after a window has been de-exposed, to save a snapshot of the window for use in an application switcher or similar. The expose keeps its semantics of being a barrier signaling that the application can now render at will, for example in a threaded render loop. There are two compatibility code paths in this patch: 1. For platform plugins that do not yet report the PaintEvents capability, QtGui will synthesize paint events on the platform's behalf, based on the existing expose events coming from the platform. 2. For applications that do not yet implement paintEvent, QtGui will send expose events instead, ensuring the same behavior as before. For now none of the platform plugins deliver paint events natively, so the first compatibility code path is always active.

* Refactor pointer event hierarchyShawn Rutledge2020-07-101-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some goals that have hopefully been achieved are: - make QPointerEvent and QEventPoint resemble their Qt Quick counterparts to such an extent that we can remove those wrappers and go back to delivering the original events in Qt Quick - make QEventPoint much smaller than QTouchEvent::TouchPoint, with no pimpl - remove most public setters - reduce the usage of complex constructors that take many arguments - don't repeat ourselves: move accessors and storage upwards rather than having redundant ones in subclasses - standardize the set of accessors in QPointerEvent - maintain source compatibility as much as possible: do not require modifying event-handling code in any QWidget subclass To avoid public setters we now introduce a few QMutable* subclasses. This is a bit like the Builder pattern except that it doesn't involve constructing a separate disposable object: the main event type can be cast to the mutable type at any time to enable modifications, iff the code is linked with gui-private. Therefore event classes can have less-"complete" constructors, because internal Qt code can use setters the same way it could use the ones in QTouchEvent before; and the event classes don't need many friends. Even some read-accessors can be kept private unless we are sure we want to expose them.

Instead, add a new flag that is set explicitly when the qt_popup_down widget is closed, and remove buttons from the move move events only when that flag is set. Add the sorely missing test case as well, even if we have to accept that not all behavior can be tested reliably. Ie. on macOS, the simulated mouse event differs from the event we do get from the QPA plugin or the system; on Xcb, some of the behavior depends on the window manager. This is something we could try to clean up for Qt 6.

* Introduce QInputDevice hierarchy; replace QTouchDeviceShawn Rutledge2020-06-161-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have seen during the Qt 5 series that QMouseEvent::source() does not provide enough information: if it is synthesized, it could have come from any device for which mouse events are synthesized, not only from a touchscreen. By providing in every QInputEvent as complete information about the actual source device as possible, we will enable very fine-tuned behavior in the object that handles each event. Further, we would like to support multiple keyboards, pointing devices, and named groups of devices that are known as "seats" in Wayland. In Qt 5, QPA plugins registered each touchscreen as it was discovered. Now we extend this pattern to all input devices. This new requirement can be implemented gradually; for now, if a QTWSI input event is received wtihout a device pointer, a default "core" device will be created on-the-fly, and a warning emitted. In Qt 5, QTouchEvent::TouchPoint::id() was forced to be unique even when multiple devices were in use simultaneously. Now that each event identifies the device it came from, this hack is no longer needed. A stub of the new QPointerEvent is added; it will be developed further in subsequent patches. [ChangeLog][QtGui][QInputEvent] Every QInputEvent now carries a pointer to an instance of QInputDevice, or the subclass QPointingDevice in case of mouse, touch and tablet events. Each platform plugin is expected to create the device instances, register them, and provide valid pointers with all input events. If this is not done, warnings are emitted and default devices are created as necessary. When the device has accurate information, it provides the opportunity to fine-tune behavior depending on device type and capabilities: for example if a QMouseEvent is synthesized from a touchscreen, the recipient can see which touchscreen it came from. Each device also has a seatName to distinguish users on multi-user windowing systems. Touchpoint IDs are no longer unique on their own, but the combination of ID and device is.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With nested popup widgets, pressing a mouse button on the lower popup will close the active popup. MouseMove events that are generated before the button is released again should not have that button included, as it is likely to result in incorrect state handling in the widget. This change removes all buttons from the MouseMove event, which is the second best option. This is mostly consistent with the behavior when closing a popup and no other popup remains. The widget underneath will get MouseMove events without the respective button included. This change doesn't include a fix for the final release event, which should ideally also not be delivered to the remaining popup, as it never got a corresponding press event. Qt has already reset the states in which it stores which widget received the press event at the time the release is generated, such as qt_button_down and qt_popup_down. So we can't separate a release grabbed by a newly opened popup (which we want) from a release to the popup that became active after closing (which we don't want). However, widgets can more easily work around this issue, and the risk of breaking things by changing the code further becomes too high.
