Package org.eclipse.nebula.widgets.nattable.group.action

Class ColumnGroupHeaderReorderDragMode

java.lang.Object

org.eclipse.nebula.widgets.nattable.viewport.action.AutoScrollDragMode

org.eclipse.nebula.widgets.nattable.reorder.action.ColumnReorderDragMode

org.eclipse.nebula.widgets.nattable.group.action.ColumnGroupHeaderReorderDragMode

All Implemented Interfaces:

IDragMode

public class ColumnGroupHeaderReorderDragMode
extends ColumnReorderDragMode

Default IDragMode invoked for 'left click + drag' on the column group header.

It overrides the isValidTargetColumnPosition() to calculate if a destination position is valid for the column group to be reordered to.

Example, a column group cannot only be reordered to be inside another column group.
