详细描述

ColorAnimation is a specialized PropertyAnimation that defines an animation to be applied when a color value changes.

Here is a ColorAnimation applied to the color property of a Rectangle as a property value source. It animates the color property's value from its current value to a value of "red", over 1000 milliseconds:

import QtQuick 2.0
Rectangle {
    width: 100; height: 100
    color: "red"
    ColorAnimation on color { to: "yellow"; duration: 1000 }
}
					

Like any other animation type, a ColorAnimation can be applied in a number of ways, including transitions, behaviors and property value sources. The Qt Quick 中的动画和过渡 documentation shows a variety of methods for creating animations.

For convenience, when a ColorAnimation is used in a Transition , it will animate any color properties that have been modified during the state change. If a property or properties are explicitly set for the animation, then those are used instead.

特性文档编制

from : color

This property holds the color value at which the animation should begin.

For example, the following animation is not applied until a color value has reached "#c0c0c0":

Item {
    states: [
        // States are defined here...
    ]
    transitions: Transition {
        ColorAnimation { from: "#c0c0c0"; duration: 2000 }
    }
}
						

若 ColorAnimation is defined within a Transition or Behavior , this value defaults to the value defined in the starting state of the Transition , or the current value of the property at the moment the Behavior 被触发。

to : color

This property holds the color value at which the animation should end.

若 ColorAnimation is defined within a Transition or Behavior , this value defaults to the value defined in the end state of the Transition , or the value of the property change that triggered the Behavior .
