top (Rectangle.top property)

public top : Number

The y coordinate of the top-left corner of the rectangle. Changing the top property of a Rectangle object has no effect on the x and width properties. However it does affect the height property; whereas changing the y value does not affect the height property.

The value of the top property is equal to the value of the y property.

Availability: ActionScript 1.0; Flash Player 8

Example

This example changes the value of the top property from 0 to 10. Notice that rect.y also changes, as does rect.height:

import flash.geom.Rectangle;

var rect:Rectangle = new Rectangle(0, 0, 100, 100);
trace(rect.top); // 0
trace(rect.y); // 0
trace(rect.height); // 100


rect.top = 10;
trace(rect.top); // 10
trace(rect.y); // 10
trace(rect.height); // 90
