Type: JadeSkinWindowStateImage
Availability: Read or write at any time
The myVerticalGripBar property of the JadeSkinJadeDockBase class contains a reference to the image drawn vertically for the grip bar for a horizontally aligned docking control (that is, the grip bar is the two vertical lines at the left of the image).
The image is stretched to fit the height of the docking control. The standard docking control grip is drawn if you do not supply an image.
