GhostWire CheckBox [Positioning]
The CheckBox (without Label) is a very flexible flash component. You can position it top-left, top-center, top-right, center-left, center, center-right, bottom-left, bottom-center, and bottom-right.

To use the CheckBox component, you should have the item you want to associate the checkbox with on the Stage. Yes, this is separate from the checkbox so the item could be anything - a bitmap, a symbol, a text, whatever.

Next, resize the CheckBox on the Stage using the Free Transform Tool (Q). As you resize, you will see the bluish box being drawn, which shows where the hotspot will be when published. Stretch your checkbox and position it to cover your associated item.

Positioning of the CheckBox within the hotspot area is defined using the two properties "Horizontal Alignment" and "Vertical Alignment".
