Struct qt_gui::QHelpEvent
source · #[repr(C)]pub struct QHelpEvent { /* private fields */ }
Expand description
The QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.
C++ class: QHelpEvent
.
The QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.
This event can be intercepted in applications to provide tooltips or "What's This?" help for custom widgets. The type() can be either QEvent::ToolTip or QEvent::WhatsThis.

&self,
other: impl CastInto<Ref<QHelpEvent>>
) -> Ref<QHelpEvent>
pub unsafe fn copy_from( &self, other: impl CastInto<Ref<QHelpEvent>> ) -> Ref<QHelpEvent>
The QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.
Calls C++ function: QHelpEvent& QHelpEvent::operator=(const QHelpEvent& other)
.

sourcepub unsafe fn global_pos(&self) -> Ref<QPoint>
pub unsafe fn global_pos(&self) -> Ref<QPoint>
Returns the mouse cursor position when the event was generated in global coordinates.
Calls C++ function: const QPoint& QHelpEvent::globalPos() const
.
sourcepub unsafe fn new(
type_: Type,
pos: impl CastInto<Ref<QPoint>>,
global_pos: impl CastInto<Ref<QPoint>>
) -> CppBox<QHelpEvent>
pub unsafe fn new( type_: Type, pos: impl CastInto<Ref<QPoint>>, global_pos: impl CastInto<Ref<QPoint>> ) -> CppBox<QHelpEvent>
Constructs a help event with the given type corresponding to the widget-relative position specified by pos and the global position specified by globalPos.
Calls C++ function: [constructor] void QHelpEvent::QHelpEvent(QEvent::Type type, const QPoint& pos, const QPoint& globalPos)
.
Constructs a help event with the given type corresponding to the widget-relative position specified by pos and the global position specified by globalPos.
type must be either QEvent::ToolTip or QEvent::WhatsThis.
sourcepub unsafe fn new_copy(
other: impl CastInto<Ref<QHelpEvent>>
) -> CppBox<QHelpEvent>
pub unsafe fn new_copy( other: impl CastInto<Ref<QHelpEvent>> ) -> CppBox<QHelpEvent>
The QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.
Calls C++ function: [constructor] void QHelpEvent::QHelpEvent(const QHelpEvent& other)
.

sourcepub unsafe fn pos(&self) -> Ref<QPoint>
pub unsafe fn pos(&self) -> Ref<QPoint>
Returns the mouse cursor position when the event was generated, relative to the widget to which the event is dispatched.
Calls C++ function: const QPoint& QHelpEvent::pos() const
.
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.
