Struct qt_gui::QShowEvent

Expand description
The QShowEvent class provides an event that is sent when a widget is shown.
C++ class: QShowEvent
.
The QShowEvent class provides an event that is sent when a widget is shown.
There are two kinds of show events: show events caused by the window system (spontaneous), and internal show events. Spontaneous (QEvent::spontaneous()) show events are sent just after the window system shows the window; they are also sent when a top-level window is redisplayed after being iconified. Internal show events are delivered just before the widget becomes visible.
Implementations§

sourcepub unsafe fn copy_from(
&self,
other: impl CastInto<Ref<QShowEvent>>
) -> Ref<QShowEvent>
pub unsafe fn copy_from( &self, other: impl CastInto<Ref<QShowEvent>> ) -> Ref<QShowEvent>
The QShowEvent class provides an event that is sent when a widget is shown.
Calls C++ function: QShowEvent& QShowEvent::operator=(const QShowEvent& other)
.

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

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.
