QML Scale Element

The Scale element provides a way to scale an Item. More...

Scale instantiates the C++ class QGraphicsScale

This element was introduced in Qt 4.7.


Detailed Description

The Scale element gives more control over scaling than using Item's scale property. Specifically, it allows a different scale for the x and y axes, and allows the scale to be relative to an arbitrary point.

The following example scales the X axis of the Rectangle, relative to its interior point 25, 25:

 Rectangle {
     width: 100; height: 100
     color: "blue"
     transform: Scale { origin.x: 25; origin.y: 25; xScale: 3}

Property Documentation

origin.x : real

origin.y : real

The point that the item is scaled from (i.e., the point that stays fixed relative to the parent as the rest of the item grows). By default the origin is 0, 0.

xScale : real

The scaling factor for the X axis.

yScale : real

The scaling factor for the Y axis.
