When a view transition is initialized, the owning view navigator
sets the startView and endView properties
to the views the transition animates.
The navigator property is
set to the view navigator.
The lifecycle of a transition is as follows:
- The transition starts with
the
captureStartValues()method. When this method is called, the navigator is currently in the start state. At this time, the transition should capture any start values or bitmaps that it requires. - A validation pass is performed on the pending
view, and the
captureEndValues()method is called. At this time, the transition captures any properties or bitmaps representations from the pending view. - The
prepareForPlay()method is then called, which allows the transition to perform any further preparations, such as preparing a Spark effects sequence, or positioning transient elements on the display list. - After a final validation pass, if necessary,
the
play()method is called by the navigator to perform the actual transition. - Prior to any animation starting, the
startevent is dispatched. - When a transition completes, it dispatches an
endevent.
Note:Create and configure view transitions in ActionScript; you cannot create them in MXML.

transitionControlsWithContent | 속성 |
transitionControlsWithContent:Boolean| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | AIR 2.5 |
When set to true, the primary view transition
is used to transition the view navigator in its entirety,
including the action bar.
Specific transitions for the action bar are not performed.
Because the tab bar is associated with the entire application,
and not a view, view transitions do not affect it.
Note that even when set to false, there are cases
where its not feasible to transition the action bar.
For example, when the action bar does not exist in one of
the two views, or if the action bar changes size.
기본값: false.

| 런타임 버전: | AIR 2.5 |
Determine if Flex can perform a transition on action bar or tab bar content independently of the views.
Flex cannot perform a transition on the control bars independently:
- If the containing view navigator is a TabbedViewNavigator and its tab bar's visibility changes between views.
- If the value of the view navigator's
overlayControlsproperty changes between views. - If the size or visibility of the action bar changes between views.
Boolean — false if Flex determines controls bars between views are
incompatible in some way.

public function captureEndValues():void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | AIR 2.5 |
Called by the ViewNavigator during the preparation phase of a transition. It is invoked when the new view has been fully realized and validated and the action bar and tab bar content reflect the state of the new view. It is at this point that the transition can capture any values it requires from the pending view. In addition any bitmaps reflecting the state of the new view, tab bar, or action bar should be captured, if required for animation.

played on the action bar when the transition starts.
This method should be overridden by subclasses if a custom action bar
effect is required.

this method is responsible for creating the Spark effect played
on the current and next view when the transition starts.
This method should be overridden by subclasses.

getSnapshot | () | 메서드 |
protected function getSnapshot(target:UIComponent, padding:int = 4, globalPosition:Point = null):BitmapImage| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | AIR 2.5 |
Used to render snap shots of screen elements in preparation for transitioning. The bitmap is returned in the form of a BitmapImage object.
The BitmapImage is in target's parent coordiantes space -
it overlaps the target precisely if paranted to the same parent.
When moving to a different parent, make sure to adjust the
transformation of the BitmapImage to correctly account for the
change in coordinate spaces.
The updated value of the globalPosition parameter
can be used for that.
매개 변수
target:UIComponent — Display object to capture.
| |
padding:int (default = 4) | |
globalPosition:Point (default = null)globalPosition
will be updated with the origin of the BitmapImage in global
coordiantes. When moving to a different coordinate space, this
value can be used to adjust the snapshot's position so its
global position on screen doesn't change.
|
BitmapImage — BitmapImage object representing the target.
|
play | () | 메서드 |
public function play():void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | AIR 2.5 |
Called by the ViewNavigator when the transition
should begin animating.
At this time, the transition should dispatch a
start event.
prepareForPlay | () | 메서드 |
public function prepareForPlay():void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | AIR 2.5 |
Called by the ViewNavigator during the preparation phase
of a transition.
This method gives the transition the chance to create and
configure the underlying IEffect instance, or to add any transient
elements to the display list.
Example transient elements include bitmap placeholders, temporary
containers required during the transition, and other elements.
If required, a final validation pass occurs prior to the invocation
of the play() method.
If it is determined that a standard transition can be initiated,
meaning one that transitions the control bars separately from the views,
the default implementation of this method constructs
a single Parallel effect which wraps the individual effect sequences
for the view transition, the action bar transition, and the tab bar transition.
This method uses the methods, createActionBarEffect(),
createTabBarEffect(), and createViewEffect().
If transitionControlsWithContent is set to true,
or if it is determined that the control bars cannot be transitioned independently,
a single effect is created to transition the navigator in its entirety.
In this case, only createConsolidatedEffect() is invoked.
transitionComplete | () | 메서드 |
protected function transitionComplete():void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | AIR 2.5 |
Called by the transition to indicate that the transition
has completed.
This method dispatches the end event.

Dispatched when the transition completes.
TheFlexEvent.TRANSITION_START constant defines the value of the
type property of the event object for a transitionStart event.
This event will only be dispatched when there are one or more relevant listeners attached to the dispatching object.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
