## Detailed Description

The QMouseEventTransition class provides a transition for mouse events.

QMouseEventTransition is part of The State Machine Framework.

See also QState::addTransition().

## Property Documentation

### button : Qt::MouseButton

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

Access functions:

Qt::MouseButton | button () const
void | setButton ( Qt::MouseButton button )

### modifierMask : Qt::KeyboardModifiers

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

Access functions:

Qt::KeyboardModifiers | modifierMask () const
void | setModifierMask ( Qt::KeyboardModifiers modifierMask )

## Member Function Documentation

### QMouseEventTransition::QMouseEventTransition ( QState * sourceState = 0 )

Constructs a new mouse event transition with the given sourceState.

### QMouseEventTransition::QMouseEventTransition ( QObject * object, QEvent::Type type, Qt::MouseButton button, QState * sourceState = 0 )

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

### QMouseEventTransition::~QMouseEventTransition ()

Destroys this mouse event transition.

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

Reimplemented from QAbstractTransition::eventTest().

### QPainterPath QMouseEventTransition::hitTestPath () const

Returns the hit test path for this mouse event transition.

See also setHitTestPath().

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

Reimplemented from QAbstractTransition::onTransition().

### 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().
