| 60 | \brief Defines animated transitions that occur on state changes. | - | ||||||||||||
| 61 | - | |||||||||||||
| 62 | A Transition defines the animations to be applied when a \l State change occurs. | - | ||||||||||||
| 63 | - | |||||||||||||
| 64 | For example, the following \l Rectangle has two states: the default state, and | - | ||||||||||||
| 65 | an added "moved" state. In the "moved state, the rectangle's position changes | - | ||||||||||||
| 66 | to (50, 50). The added Transition specifies that when the rectangle | - | ||||||||||||
| 67 | changes between the default and the "moved" state, any changes | - | ||||||||||||
| 68 | to the \c x and \c y properties should be animated, using an \c Easing.InOutQuad. | - | ||||||||||||
| 69 | - | |||||||||||||
| 70 | \snippet qml/transition.qml 0 | - | ||||||||||||
| 71 | - | |||||||||||||
| 72 | Notice the example does not require \l{PropertyAnimation::}{to} and | - | ||||||||||||
| 73 | \l{PropertyAnimation::}{from} values for the NumberAnimation. As a convenience, | - | ||||||||||||
| 74 | these properties are automatically set to the values of \c x and \c y before | - | ||||||||||||
| 75 | and after the state change; the \c from values are provided by | - | ||||||||||||
| 76 | the current values of \c x and \c y, and the \c to values are provided by | - | ||||||||||||
| 77 | the PropertyChanges object. If you wish, you can provide \l{PropertyAnimation::}{to} and | - | ||||||||||||
| 78 | \l{PropertyAnimation::}{from} values anyway to override the default values. | - | ||||||||||||
| 79 | - | |||||||||||||
| 80 | By default, a Transition's animations are applied for any state change in the | - | ||||||||||||
| 81 | parent item. The Transition \l {Transition::}{from} and \l {Transition::}{to} | - | ||||||||||||
| 82 | values can be set to restrict the animations to only be applied when changing | - | ||||||||||||
| 83 | from one particular state to another. | - | ||||||||||||
| 84 | - | |||||||||||||
| 85 | To define multiple transitions, specify \l Item::transitions as a list: | - | ||||||||||||
| 86 | - | |||||||||||||
| 87 | \snippet qml/transitions-list.qml list of transitions | - | ||||||||||||
| 88 | - | |||||||||||||
| 89 | If multiple Transitions are specified, only a single (best-matching) Transition will be applied for any particular | - | ||||||||||||
| 90 | state change. In the example above, when changing to \c state1, the first transition will be used, rather | - | ||||||||||||
| 91 | than the more generic second transition. | - | ||||||||||||
| 92 | - | |||||||||||||
| 93 | If a state change has a Transition that matches the same property as a | - | ||||||||||||
| 94 | \l Behavior, the Transition animation overrides the \l Behavior for that | - | ||||||||||||
| 95 | state change. | - | ||||||||||||

| 330 | By default, transitions run in parallel and are applied to all state | - | ||||||||||||
| 331 | changes if the \l from and \l to states have not been set. In this | - | ||||||||||||
| 332 | situation, the transition is automatically applied when a state change | - | ||||||||||||
| 333 | is reversed, and it is not necessary to set this property to reverse | - | ||||||||||||
| 334 | the transition. | - | ||||||||||||
| 335 | - | |||||||||||||
| 336 | However, if a SequentialAnimation is used, or if the \l from or \l to | - | ||||||||||||
| 337 | properties have been set, this property will need to be set to reverse | - | ||||||||||||
| 338 | a transition when a state change is reverted. For example, the following | - | ||||||||||||
| 339 | transition applies a sequential animation when the mouse is pressed, | - | ||||||||||||
| 340 | and reverses the sequence of the animation when the mouse is released: | - | ||||||||||||

| 342 | \snippet qml/transition-reversible.qml 0 | - | ||||||||||||

| 344 | If the transition did not set the \c to and \c reversible values, then | - | ||||||||||||
| 345 | on the mouse release, the transition would play the PropertyAnimation | - | ||||||||||||
| 346 | before the ColorAnimation instead of reversing the sequence. | - | ||||||||||||
