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.

virtual IlBoolean IlvGanttSubNodeHook::afterMove ( IlvGanttNode *  node, IlUShort  i, 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.
i	The index of data in node.
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.

IlvGanttChart* IlvGanttSubNodeHook::getGanttChart

(

)

const

Gets the Gantt chart on which the hook is installed.

Returns

The Gantt chart on which the hook is installed.
