Expand description
The QPlatformSurfaceEvent class is used to notify about native platform surface events.
C++ class: QPlatformSurfaceEvent
.
The QPlatformSurfaceEvent class is used to notify about native platform surface events.
Platform window events are synchronously sent to windows and offscreen surfaces when their underlying native surfaces are created or are about to be destroyed.
Applications can respond to these events to know when the underlying platform surface exists.

sourcepub unsafe fn new(
surface_event_type: SurfaceEventType
) -> CppBox<QPlatformSurfaceEvent>
pub unsafe fn new( surface_event_type: SurfaceEventType ) -> CppBox<QPlatformSurfaceEvent>
Constructs a platform surface event for the given surfaceEventType.
Calls C++ function: [constructor] void QPlatformSurfaceEvent::QPlatformSurfaceEvent(QPlatformSurfaceEvent::SurfaceEventType surfaceEventType)
.
Constructs a platform surface event for the given surfaceEventType.

other: impl CastInto<Ref<QPlatformSurfaceEvent>>
) -> CppBox<QPlatformSurfaceEvent>
pub unsafe fn new_copy( other: impl CastInto<Ref<QPlatformSurfaceEvent>> ) -> CppBox<QPlatformSurfaceEvent>
The QPlatformSurfaceEvent class is used to notify about native platform surface events.
Calls C++ function: [constructor] void QPlatformSurfaceEvent::QPlatformSurfaceEvent(const QPlatformSurfaceEvent& other)
.

sourcepub unsafe fn surface_event_type(&self) -> SurfaceEventType
pub unsafe fn surface_event_type(&self) -> SurfaceEventType
Returns the specific type of platform surface event.
Calls C++ function: QPlatformSurfaceEvent::SurfaceEventType QPlatformSurfaceEvent::surfaceEventType() const
.
Returns the specific type of platform surface event.
Methods from Deref<Target = QEvent>§
sourcepub unsafe fn accept(&self)
pub unsafe fn accept(&self)
Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
Calls C++ function: void QEvent::accept()
.
Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget.
See also ignore().
sourcepub unsafe fn copy_from(&self, other: impl CastInto<Ref<QEvent>>) -> Ref<QEvent>
pub unsafe fn copy_from(&self, other: impl CastInto<Ref<QEvent>>) -> Ref<QEvent>
Calls C++ function: QEvent& QEvent::operator=(const QEvent& other)
.
sourcepub unsafe fn ignore(&self)
pub unsafe fn ignore(&self)
Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
Calls C++ function: void QEvent::ignore()
.
Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
Clearing the accept parameter indicates that the event receiver does not want the event. Unwanted events might be propagated to the parent widget.
See also accept().
sourcepub unsafe fn is_accepted(&self) -> bool
pub unsafe fn is_accepted(&self) -> bool
the accept flag of the event object
Calls C++ function: bool QEvent::isAccepted() const
.
the accept flag of the event object
Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but don't rely on this as subclasses may choose to clear it in their constructor.
For convenience, the accept flag can also be set with accept(), and cleared with ignore().
Access functions:
bool | isAccepted() const |
void | setAccepted(bool accepted) |
sourcepub unsafe fn set_accepted(&self, accepted: bool)
pub unsafe fn set_accepted(&self, accepted: bool)
the accept flag of the event object
Calls C++ function: void QEvent::setAccepted(bool accepted)
.
the accept flag of the event object
Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but don't rely on this as subclasses may choose to clear it in their constructor.
For convenience, the accept flag can also be set with accept(), and cleared with ignore().
Access functions:
bool | isAccepted() const |
void | setAccepted(bool accepted) |
sourcepub unsafe fn spontaneous(&self) -> bool
pub unsafe fn spontaneous(&self) -> bool
Returns true
if the event originated outside the application (a system event); otherwise returns false
.
Calls C++ function: bool QEvent::spontaneous() const
.
Returns true
if the event originated outside the application (a system event); otherwise returns false
.
The return value of this function is not defined for paint events.
