53 \inherits Animation -

54 \brief Is the base of all QML animators. -

55 -

56 Animator types are a special type of animation which operate -

57 directly on Qt Quick's scene graph, rather than the QML objects and their -

58 properties like regular Animation types do. This has the benefit that -

59 Animator based animations can animate on the \l -

60 {Threaded Render Loop ("threaded")}{scene graph's rendering thread} even when the -

61 UI thread is blocked. -

62 -

63 The value of the QML property will be updated after the animation has -

64 finished. The property is not updated while the animation is running. -

65 -

66 The Animator types can be used just like any other Animation type. -

67 -

68 \snippet qml/animators.qml mixed -

69 -

70 If all sub-animations of ParallelAnimation and SequentialAnimation -

71 are Animator types, the ParallelAnimation and SequentialAnimation will -

72 also be treated as an Animator and be run on the scene graph's rendering -

73 thread when possible. -

74 -

75 The Animator types can be used for animations during transitions, but -

76 they do not support the \l {Transition::reversible}{reversible} -

77 property. -

78 -

79 The Animator type cannot be used directly in a QML file. It exists -

80 to provide a set of common properties and methods, available across all the -

81 other animator types that inherit from it. Attempting to use the Animator -

82 type directly will result in an error. -

515 \brief The UniformAnimator type animates a uniform of a ShaderEffect. -

516 -

517 \l{Animator} types are different from normal Animation types. When -

518 using an Animator, the animation can be run in the render thread -

519 and the property value will jump to the end when the animation is -

520 complete. -

521 -

522 The value of the QML property defining the uniform is updated after -

523 the animation has finished. -

524 -

525 The following snippet shows how to use a UniformAnimator together -

526 with a ShaderEffect item. -

527 -

528 \snippet qml/animators.qml shader target -

529 -

530 It is also possible to use the \c on keyword to tie the -

531 UniformAnimator directly to a uniform of a ShaderEffect -

532 instance. -
