How to Create a Flash MX Component - Page 5

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);
}
