Detailed Description
The switcher view draws a background for the switcher.
Constructor & Destructor Documentation
| SwitcherViewBase::SwitcherViewBase | ( | Switcher * | controller | ) |
Constructs a SwitcherViewBase.
- Parameters:
-
container the Switcher controller to be used
| SwitcherViewBase::~SwitcherViewBase | ( | ) | [virtual] |
Destroys the SwitcherViewBase.
Member Function Documentation
| void SwitcherViewBase::animationStateChanged | ( | bool | animating | ) | [signal] |
Sent when switcher starts or stops animating
| void SwitcherViewBase::applyPinchGestureTargetMode | ( | ) | [protected, virtual, slot] |
Sets the switcher mode according to current pinch gesture target
Reimplemented in SwitcherView.
| void SwitcherViewBase::applySwitcherMode | ( | ) | [protected, virtual] |
Selects the layout policy and sets up switcher mode dependent signals
Reimplemented in SwitcherView.
| int SwitcherViewBase::buttonIndex | ( | const SwitcherButton * | button | ) | const [protected] |
Returns the index of a SwitcherButton in the model or -1, if not found
| void SwitcherViewBase::calculateNearestButtonAt | ( | const QPointF & | centerPoint | ) | [protected] |
Calculates which switcher button is nearest to point centerPoint.
| void SwitcherViewBase::endBounce | ( | ) | [protected, virtual, slot] |
Ends the bounce effect
| void SwitcherViewBase::endTransition | ( | ) | [protected, virtual, slot] |
Ends the transition between switcher modes
| bool SwitcherViewBase::event | ( | QEvent * | e | ) |
REIMPLEMENTATION Re-implented event handler. Needed to enable gestures.
- Parameters:
-
e event to be handled
- Returns:
- true if event was accepted, otherwise false
| void SwitcherViewBase::pinchBegin | ( | const QPointF & | centerPoint | ) | [protected, virtual] |
Called when the pinch gesture starts
- Parameters:
-
centerPoint the center point of the pinch gesture
| void SwitcherViewBase::pinchEnd | ( | ) | [protected, virtual] |
Called when the pinch gesture ends
| void SwitcherViewBase::pinchGestureEvent | ( | QGestureEvent * | event, | |
| QPinchGesture * | gesture | |||
| ) | [protected, virtual] |
Re-implemented to handle the mode switch
- Parameters:
-
event Gesture event class for general event handling. gesture Pinch gesture class. Contains all pinch specific information
Finish any currently running animation before starting a new one
| void SwitcherViewBase::pinchUpdate | ( | float | scaleFactor | ) | [protected, virtual] |
Called to update the scale factor during the pinch gesture
- Parameters:
-
scaleFactor the updated scale factor
| void SwitcherViewBase::removeButtonsFromLayout | ( | ) | [protected] |
Remove all buttons from layout and set parents to NULL Parents are set to NULL to avoid double deletion as buttons are QSharedPointer's in model
| void SwitcherViewBase::runOverviewBounceAnimation | ( | ) | [protected, slot] |
Runs the bounce animation if currently in overview mode
| bool SwitcherViewBase::sceneEventFilter | ( | QGraphicsItem * | watched, | |
| QEvent * | event | |||
| ) | [protected, virtual] |
Filters QGraphicsSceneMouseMove events from SwitcherButtons.
| void SwitcherViewBase::setInwardBounceAnimation | ( | bool | i | ) | [protected] |
Sets the direction of the bounce animation
| void SwitcherViewBase::setupModel | ( | ) | [protected, virtual] |
REIMPLEMENTATION Re-implemented here to get an update when the model is set
| void SwitcherViewBase::startBounceAnimation | ( | ) | [protected, virtual] |
Starts the bounce animation
| void SwitcherViewBase::updateAnimationStatus | ( | ) | [protected, virtual, slot] |
Updates the animation status and sends animationStateChanged signal if status changed
| void SwitcherViewBase::updateData | ( | const QList< const char * > & | modifications | ) | [protected, virtual, slot] |
REIMPLEMENTATION
Reimplemented in SwitcherView.
