Detailed Description

Gantt chart subnode hook class.

Library: ilvgantt

The IlvGanttSubNodeHook class is used to capture the modifications on a subnode when users use IlvGanttSelectInteractor to manipulate the subnode.

It is recommended that you use this class in the following manner:

• Create your subclass of IlvGanttSubNodeHook.
• Use the IlvGanttChart::setSubNodeHook method to install your subnode hook.
• The virtual methods of your subclass will be called automatically when the end-user manipulates the subnodes of the Gantt chart.

		IlvGanttSubNode *	data
	)			[virtual]

Called when a user of a Gantt chart has moved a subnode.

This virtual method is called when a user of the Gantt chart has moved a subnode.

Parameters:

	node	The node of data.
	i	The index of data in node.
	data	The manipulated subnode.

virtual IlBoolean IlvGanttSubNodeHook::afterReshape	(	IlvGanttNode *	node,
		IlUShort	i,
		IlvGanttSubNode *	data
	)			[virtual]

Called when a user of a Gantt chart has reshaped a subnode.

This virtual method is called when a user of the Gantt chart has reshaped a subnode.

Parameters:

	node	The node of data.
	i	The index of data in node.
	data	The manipulated subnode.

virtual IlBoolean IlvGanttSubNodeHook::beforeMove	(	IlvGanttNode *	node,
		IlUShort	i,
		IlvGanttSubNode *	data
	)			[virtual]

Called when a user of a Gantt chart moves a subnode.

This virtual method is called when a user of a Gantt chart moves a subnode using IlvGanttSelectInteractor.

Parameters:

	node	The node of data.

	data	The manipulated subnode.

Returns:

If IlTrue, the IlvGanttSelectInteractor will move the subnode. Otherwise, IlvGanttSelectInteractor will abort its operation and the subnode will not be moved.

virtual IlBoolean IlvGanttSubNodeHook::beforeReshape	(	IlvGanttNode *	node,
		IlUShort	i,
		IlvGanttSubNode *	data
	)			[virtual]

Called when a user of a Gantt chart reshapes a subnode.

This virtual method is called when a user of a Gantt chart reshapes a subnode using IlvGanttSelectInteractor.

Parameters:

	node	The node to be reshaped.
	i	The index of the subnode in the node.
	data	The manipulated subnode.

Returns:

If IlTrue the IlvGanttSelectInteractor will reshape the subnode. Otherwise, IlvGanttSelectInteractor will abort its operation and the subnode will not be reshaped.
