How to Create a Flash MX Component

Step 3. Defining the Read and Write Methods for the Triangle Properties
It is time to define other methods we need for this component, namely those
that set and access the base, height, and tint color values. As well, we will
add a method to compute the area of the triangle. For the set routines, once
we change the value to the value passed in, we redraw the triangle. For the
get routines, we simply return the property value. Add the following methods
within the same #initclip/#endinitclip block, any place after the MovieClip
inheritance statement:
TriangleClass.prototype.setBase = function (b) {
this.tbase = b;
this.update();
}
TriangleClass.prototype.getBase = function () {
return (this.tbase);
}
TriangleClass.prototype.setHeight = function (h) {
this.theight = h;
this.update();
}
TriangleClass.prototype.getHeight = function () {
return (this.theight);
}
TriangleClass.prototype.setTintColor = function (c) {
this.tcolor = c;
this.update();
}
TriangleClass.prototype.turnOnTint = function () {
this.applyTint = true;
this.update();
}
TriangleClass.prototype.getArea = function () {
return (0.5 * this.tbase * this.theight);
}
