public class LineSelectionSettingPanel
extends Panel
implements LayoutRearrangeable

This class provide a graphic interface to control the ncsa.horizon.awt.LineSelection.
It is implemented as a panel with Checkbox, ncsa.horizon. awt.LabeledFields, Choices, and ncsa.horizon.awt.IntScrollPanels to make LineSelection visible or invisible, set LineSelection color, position, delta_x, delta_y, and thickness. The panel will update its position, width, height text field, and visibility CheckBox as LineSelection changes position and becomes visible or invisible.
