Scaling with BorderImage

BorderImage shows the various scaling modes of the BorderImage type by setting its horizontalTileMode and verticalTileMode properties.

图像填充

图像 shows the various fill modes of the Image 类型。

Shadow Effects

Shadows shows how to create a drop shadow effect for a rectangular item using a BorderImage :

    BorderImage {
        anchors.fill: rectangle
        anchors { leftMargin: -6; topMargin: -6; rightMargin: -8; bottomMargin: -8 }
        border { left: 10; top: 10; right: 10; bottom: 10 }
        source: "shadow.png"
    }
					
					

Sprite Animations with AnimatedSprite

AnimatedSprite shows how to display a simple animation using an AnimatedSprite 对象:

    AnimatedSprite {
        id: sprite
        anchors.centerIn: parent
        source: "content/speaker.png"
        frameCount: 60
        frameSync: true
        frameWidth: 170
        frameHeight: 170
        loops: 3
    }
					

The sprite animation will loop three times.

Sprite Animations with SpriteSequence

SpriteSequence demonstrates using a sprite sequence to draw an animated and interactive bear. The SpriteSequence object defines five different sprites. The bear is initially in a still state:

        Sprite{
            name: "still"
            source: "content/BearSheet.png"
            frameCount: 1
            frameWidth: 256
            frameHeight: 256
            frameDuration: 100
            to: {"still":1, "blink":0.1, "floating":0}
        }
					

When the scene is clicked, an animation sets the sprite sequence to the falling states and animates the bear's y property.

    SequentialAnimation {
        id: anim
        ScriptAction { script: image.goalSprite = "falling"; }
        NumberAnimation { target: image; property: "y"; to: 480; duration: 12000; }
        ScriptAction { script: {image.goalSprite = ""; image.jumpTo("still");} }
        PropertyAction { target: image; property: "y"; value: 0 }
    }
					

At the end of the animation the bear is set back to its initial state.
