Struct qt_gui::QFocusEvent

#[repr(C)]pub struct QFocusEvent { /* fields omitted */ }

The QFocusEvent class contains event parameters for widget focus events.

C++ class: QFocusEvent.

C++ documentation:

The QFocusEvent class contains event parameters for widget focus events.

Focus events are sent to widgets when the keyboard input focus changes. Focus events occur due to mouse actions, key presses (such as Tab or Backtab), the window system, popup menus, keyboard shortcuts, or other application-specific reasons. The reason for a particular focus event is returned by reason() in the appropriate event handler.

The event handlers QWidget::focusInEvent(), QWidget::focusOutEvent(), QGraphicsItem::focusInEvent and QGraphicsItem::focusOutEvent() receive focus events.

Methods

impl QFocusEvent

pub unsafe fn got_focus(&self) -> bool

Returns true if type() is QEvent::FocusIn; otherwise returns false.

Calls C++ function: bool QFocusEvent::gotFocus() const.

C++ documentation:

Returns true if type() is QEvent::FocusIn; otherwise returns false.

pub unsafe fn lost_focus(&self) -> bool

Returns true if type() is QEvent::FocusOut; otherwise returns false.

Calls C++ function: bool QFocusEvent::lostFocus() const.

C++ documentation:

Returns true if type() is QEvent::FocusOut; otherwise returns false.

pub unsafe fn new_2a(type_: Type, reason: FocusReason) -> CppBox<QFocusEvent>

Constructs a focus event object.

Calls C++ function: [constructor] void QFocusEvent::QFocusEvent(QEvent::Type type, Qt::FocusReason reason = …).

C++ documentation:

Constructs a focus event object.

The type parameter must be either QEvent::FocusIn or QEvent::FocusOut. The reason describes the cause of the change in focus.

pub unsafe fn new_1a(type_: Type) -> CppBox<QFocusEvent>

Constructs a focus event object.

Calls C++ function: [constructor] void QFocusEvent::QFocusEvent(QEvent::Type type).

C++ documentation:

Constructs a focus event object.

The type parameter must be either QEvent::FocusIn or QEvent::FocusOut. The reason describes the cause of the change in focus.

C++ documentation:

Returns the reason for this focus event.
