## Property Documentation

### `[bindable]` button : Qt::MouseButton

Note: This property supports QProperty bindings.

This property holds the button that this mouse event transition is associated with

### `[bindable]` modifierMask : Qt::KeyboardModifiers

Note: This property supports QProperty bindings.

This property holds the keyboard modifier mask that this mouse event transition checks for

## Member Function Documentation

### QMouseEventTransition::QMouseEventTransition(QState *sourceState = nullptr)

Constructs a new mouse event transition with the given sourceState.

### QMouseEventTransition::QMouseEventTransition(QObject *object, QEvent::Type type, Qt::MouseButton button, QState *sourceState = nullptr)

Constructs a new mouse event transition for events of the given type for the given object, with the given button and sourceState.

### `[virtual noexcept]` QMouseEventTransition::~QMouseEventTransition()

Destroys this mouse event transition.

### Qt::MouseButton QMouseEventTransition::button() const

Returns the button that this mouse event transition checks for.

Note: Getter function for property button.

See also setButton().

### `[override virtual protected]` bool QMouseEventTransition::eventTest(QEvent *event)

Reimplements: QEventTransition::eventTest(QEvent *event).

### QPainterPath QMouseEventTransition::hitTestPath() const

Returns the hit test path for this mouse event transition.

See also setHitTestPath().

### Qt::KeyboardModifiers QMouseEventTransition::modifierMask() const

Returns the keyboard modifier mask that this mouse event transition checks for.

Note: Getter function for property modifierMask.

See also setModifierMask().

### `[override virtual protected]` void QMouseEventTransition::onTransition(QEvent *event)

Reimplements: QEventTransition::onTransition(QEvent *event).

### void QMouseEventTransition::setButton(Qt::MouseButton button)

Sets the button that this mouse event transition will check for.

Note: Setter function for property button.

See also button().

### void QMouseEventTransition::setHitTestPath(const QPainterPath &path)

Sets the hit test path for this mouse event transition to path. If a valid path has been set, the transition will only trigger if the mouse event position (QMouseEvent::pos()) is inside the path.

See also hitTestPath() and QPainterPath::contains().

### void QMouseEventTransition::setModifierMask(Qt::KeyboardModifiers modifierMask)

Sets the keyboard modifier mask that this mouse event transition will check for to modifierMask.

Note: Setter function for property modifierMask.

See also modifierMask().
