Class ColumnGroupHeaderReorderDragMode

All Implemented Interfaces:

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.
