I tried to make a container class that would look like a black rectangle with a dark gray drop-shadow using rectagles. I put all the 'this.xxx.width=' and 'this.xxx.height=' code in the the resize event of the container, expecting that when I resize the container in design mode, the rectangles would update.

However, the resize method does not fire in design mode, and the rectangles stay the same size, even though the container frame has been resized.

What gives?
