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