how to draw rounded Rectangle

[AS3.0]

Hello, I put randomize colors for each button press.

On lines 168:

randomizeArray(colors)//Randomize the order of the colors.
for(var i=0;i<text_array_1.length;i++){
updateRectangle(0,0,Stage.width,100,colors[i],0xFFFF33,"50%",3,_root["mc"+i]);//Update the rectangle colors with the new order.
}
