public _xscale : Number

The horizontal scale of the button as applied from the registration point of the button, expressed as a percentage. The default registration point is (0,0).

Scaling the local coordinate system affects the _x and _y property settings, which are defined in pixels. For example, if the parent movie clip is scaled to 50%, setting the _x property moves an object in the button by half the number of pixels that it would if the SWF file were at 100%.

Example

The following example scales a button called my_btn. When you click and release the button, it grows 10% on the x and y axis. Enter the following ActionScript in Frame 1 of the Timeline:

my_btn.onRelease = function(){
    this._xscale ~= 1.1;
    this._yscale ~= 1.1;
};
