GhostWire ScrollPane [EdgeSense]
The EdgeSense behavior is an addon for the ScrollPane component.  To use, drag from the Components Panel and drop it on an instance of the ScrollPane on the Stage.

The EdgeSense instance has no visual asset, only a 8x8 pixels invisible clip for identification purpose.  It is recommended that you Distribute to Layers, placing each asset on the Stage on a separate layer for easy selection.

When you select the EdgeSense, you will be able to configure its properties (via the Properties Panel).

senseMode
This property can have two possible values - "MovieClip" or "Stage".  When set to "MovieClip", the hotspot area is the edge of the scrollpane.  When set to "Stage", the hotspot area is the edge of the application.  "MovieClip" is selected by default.  If you are building a fullscreen application, the "Stage" mode becomes useful.

edgeSize
This property determines the size of the hotspot area when the senseMode is set to "MovieClip".   The size is measured in pixels.  If it is a positive number, the hotspot area starts from the edge of the scrollpane to X pixels *outside* of it.  If it is a negative number, the hotspot area starts from the edge of the scrollpane to X pixels *inside* of it.  If the property is set to 0 (zero), the hotspot area starts from the edge of the scrollpane to the edge of the application.
