Detailed Description

Gantt chart node class.

Library: ilvgantt

An IlvGanttNode object describes a Gantt activity. It handles a set of IlvGanttSubNode objects. An IlvGanttNode is used to handle subnode activities. It can also be used to handle breaks. A node that handles breaks is called a break node. Subnodes handled by a break node are called break subnodes.

To create a break node, call the IlvGanttNode constructor, setting the asBreak parameter to IlTrue.

Subnodes added to a break node should be break subnodes.

See also: IlvGanttChart, IlvGanttAbstractObject, IlvGanttSubNode.

Constructor & Destructor Documentation

◆ IlvGanttNode() [1/2]

IlvGanttNode::IlvGanttNode	(	const char *	name,
		IlBoolean	copy = `IlTrue`,
		IlBoolean	asBreak = `IlFalse`
	)

Initializes an empty IlvGanttNode object.

The new IlvGanttNode object becomes a skeleton: you can call member functions such as addSubNode() to add IlvGanttSubNode objects to the IlvGanttNode object.

Parameters

name	The name of the Gantt node.
copy	Specifies whether the object stores a copy of name or the string name itself.
asBreak	Specifies whether the new node is a break node.

◆ IlvGanttNode() [2/2]

IlvGanttNode::IlvGanttNode	(	const char *	name,
		IlBoolean	copy,
		IlUInt	count,
			...
	)

Initializes a new IlvGanttNode from a series of IlvGanttSubNode objects.

The IlvGanttSubNode objects are provided as the parameters following count.

Parameters

name	The name of the Gantt node.
copy	Specifies whether the object stores a copy of name or the string name itself.
count	The number of subnodes in the node. This should also be the number of parameters that follow count, and all must be pointers to valid instances of `IlvGanttSubNode`.

◆ ~IlvGanttNode()

virtual IlvGanttNode::~IlvGanttNode ( )

virtual

Destructor.

The destructor deletes the subnode graphic model that the user may have set, and the string name stored in this Gantt node. It also calls the destructor of the subnodes stored in the Gantt node.

Member Function Documentation

◆ addSubNode()

void IlvGanttNode::addSubNode ( IlvGanttSubNode * subnode )

Adds a subnode.

Adds the subnode subnode at the end of the subnode list.

Parameters

subnode The subnode to add.

◆ getCardinal()

IlUShort IlvGanttNode::getCardinal ( ) const

Returns the total number of subnodes stored in the node.

Returns: The total number of subnodes.

◆ getDrawMode()

IlvGanttNodeDrawMode IlvGanttNode::getDrawMode ( ) const

Gets the presentation mode.

Returns the presentation mode for this node, which can be one of the following values indicating the left and right positions of the graphic object representing the node:

IlvGanttNodeDrawMin - Draws the node between startMin and endMin.
IlvGanttNodeDrawMax - Draws the node between startMax and endMax.
IlvGanttNodeDrawComplete - Draws the node between startMin and endMax.
IlvGanttNodeDrawDefault - Draws the node using the mode set with the setDrawMode() member function.

Returns: The presentation mode for this node.

◆ getSubGraphicModel()

IlvGraphic* IlvGanttNode::getSubGraphicModel ( ) const

Returns the subnode graphic model that the user may have set.

Returns: The subnode graphic model.

◆ getSubNode()

IlvGanttSubNode* IlvGanttNode::getSubNode ( IlUShort index ) const

Gets a subnode.

Returns the index ^th subnode. The first subnode has an index of 0.

Parameters

index The position of the subnode.

Returns: The index ^th subnode.

◆ getSubNodes()

IlvGanttSubNode* const* IlvGanttNode::getSubNodes ( IlUShort & count ) const

Gets the subnodes stored in the node.

The returned array must not be deleted by the programmer, as it is internally maintained.

Parameters

count Set to the number of subnodes in the array.

Returns: An array of pointers to the subnodes stored in the node.

◆ isBreak()

IlBoolean IlvGanttNode::isBreak ( ) const

Indicates whether the node is a break node.

Returns: IlTrue if the node is a break node.

◆ removeSubNode()

void IlvGanttNode::removeSubNode ( IlUShort index )

Removes a subnode.

Removes the index ^th subnode from the subnode list.

Parameters

index The position of the subnode to remove.

◆ setDrawMode()

void IlvGanttNode::setDrawMode ( IlvGanttNodeDrawMode mode )

Sets the presentation mode.

Sets the presentation mode for this node to the value given by the mode parameter. The mode parameter can be set to one of four values indicating the left and right positions of the graphic object representing the node:

IlvGanttNodeDrawMin - Draws the node between startMin and endMin.
IlvGanttNodeDrawMax - Draws the node between startMax and endMax.
IlvGanttNodeDrawComplete - Draws the node between startMin and endMax.
IlvGanttNodeDrawDefault - Draws the node using the mode set with the setDrawMode() member function.

Parameters

mode	The presentation mode.

◆ setSubGraphicModel()

void IlvGanttNode::setSubGraphicModel	(	IlvGraphic *	graphic,
		IlBoolean	destroyOld = `IlTrue`
	)

Sets the subnode graphic model for this Gantt node to a given graphic object.

This model is used to draw the subnodes of this node. You can specify IlFalse as the value of the destroyOld parameter to not call delete for the old graphic model.

Parameters

graphic	The `IlvGraphic` that will become the subnode graphic model.
destroyOld	Indicates whether the old graphic model is destroyed.
