Detailed Description

Gantt chart form class.

Library: ilvgantt

IlvGanttChartForm is a subclass of IlvGanttChart. It has the following additional features:

<align="center">

An IlvGanttChartForm

The Gantt chart form is divided into several separate viewing areas, which are referred to as panes. There are three vertical panes split by two horizontal splitters, and three horizontal panes split by two vertical splitters.
The first vertical pane (on the left) is used to show resources. This pane is called a resource table.
There are two scale views on the top of the Gantt chart form. They are used to show a multilevel scale. The construction of a multilevel scale is shown in the sample.
The handle box of IlvGanttChart is not accessible by users of the Gantt. It is replaced by the splitters. The size of the panes can be adjusted by dragging the splitters. You can even collapse a pane by dragging a splitter and dropping it on another splitter. Similarly you can do the opposite to expand a collapsed pane.

The resource table has three parts:

The resource header is at the top of the table. It is mainly used to show the titles of each column of the resource table. In addition, you can adjust the widths of the columns in the same way as you would resize the columns of an IlvSheet. The resource header is an object of the class IlvGanttResourceHeader, which is a subclass of IlvSheet. An IlvGanttResourceHeader is a single row IlvSheet that can be used in exactly the same way as an IlvSheet.
The resources are listed in the main part of the table. Each line displays a resource and is a separate object of the class IlvGanttResourceLine. An IlvGanttResourceLine is a single row IlvScrolledMatrix.
At the bottom of the table is a horizontal scroll bar.

After an IlvGanttChartForm is created, you must create an IlvGanttResourceLine and call the setLineGraphicModel() method in order to specify the IlvGanttResourceLine as the line graphic mode of the IlvGanttChartForm.

For more information on the Gantt chart form, read the $ILVHOME/samples/gantt/calendar/readme.txt file.

margin	Specifies the spacing in pixels between the left, right, top, or bottom edge of Gantt chart and any scale, scroll bar, or view.
separSize	Specifies the width or height in pixels of a square box positioned on the middle of the grapher views. This box allows users to adjust the size of the manager and the grapher views by using the mouse.
hasScale	This parameter is ignored. The scales are always on the top.
hasHSB	This parameter is ignored. The horizontal scroll bars are always at the bottom.
hasVSB	This parameter is ignored. The vertical scroll bars are always on the right.
numLayers	Indicates the number of layers to be handled by the grapher.
useAcc	An `IlBoolean` indicating whether the default accelerators are to be set (for a list of the default accelerators, see Table "Default manager and grapher accelerators").
palette	Specifies the graphic resources of different Gantt chart components (views, scales, scroll bars, handle box). An inverted palette is computed from the given palette and used to draw the lines and nodes added to the Gantt chart.

Member Function Documentation

§ deleteAll()

virtual void IlvGanttChartForm::deleteAll	(	IlBoolean	destroy,
		IlBoolean	redraw = `IlTrue`

Parameters

destroy	Specifies whether objects are destroyed after they are removed.
redraw	Specifies whether you want the manager and the grapher to redraw their views.

Reimplemented from IlvGanttChart.

§ getCompositeGrid()

IlvGraphic* IlvGanttChartForm::getCompositeGrid ( ) const

Gets the composite grid currently being used.

Returns the composite grid currently used in the Gantt chart form.

Note: This method is deprecated. Use IlvGanttChart::getRowGrid() instead.

Returns: The composite grid currently used. It returns 0 if no composite grid has been set.

§ getCompositeScale()

IlvGraphic* IlvGanttChartForm::getCompositeScale ( ) const

Gets the composite scale currently being used.

Returns the composite scale currently used in the Gantt chart form.

Returns: The composite scale currently used. It returns 0 if no composite scale has been set.

§ getLineArea()

virtual IlvRect& IlvGanttChartForm::getLineArea ( IlvRect & area ) const

virtual

Returns the bounds of the Gantt lines.

This function computes the bounding box of the Gantt lines.

Parameters

area	The bounds of the Gantt lines.

Returns: The reference to area.

Reimplemented from IlvGanttChart.

§ getResourceHeader()

IlvGanttResourceHeader* IlvGanttChartForm::getResourceHeader ( ) const

Gets the resource header.

Returns the resource header that is on the top left of the Gantt chart form.

Returns: The resource header. It returns null if the makeView method has not been called.

§ getResourceScrollBar()

IlvScrollBar* IlvGanttChartForm::getResourceScrollBar ( ) const

Gets the resource table scroll bar.

Returns the resource table scroll bar that is on the bottom left of the Gantt chart form.

Returns: The resource table scroll bar. It returns null if the makeView method has not been called.

§ getScaleView()

IlvView* IlvGanttChartForm::getScaleView ( IlUShort viewIndex ) const

Gets the scale view.

Returns the scale view that is on the top right of the Gantt chart form.

Parameters

viewIndex Valid values are 0 and 1.

Returns: The scale view. It returns null if the makeView method has not been called.

§ horizontalSplitter()

IlvSplitterGadget* IlvGanttChartForm::horizontalSplitter ( IlInt index ) const

Gets the horizontal splitter.

Returns the horizontal splitter of the Gantt chart form.

Parameters

index Valid values are 0 and 1.

Returns: The horizontal splitter of the Gantt chart form. It returns null if the makeView method has not been called.

§ insertLine()

virtual void IlvGanttChartForm::insertLine	(	IlvGanttLine *	line,
		IlUShort	row,
		IlBoolean	redraw = `IlTrue`,
		int	layer = `-1`
	)

virtual

Inserts a line before a row.

If this line already encapsulates a graphic object, this object is added to the Gantt manager. Otherwise, the Gantt chart creates a default graphic object, either by copying a graphic model provided by the user (if any), or by using the IlvMessageLabel constructor, and then adds it to the manager.

If row is greater than the actual number of lines in the chart, the line is added after the last row if the chart does not have a hidden line containing free nodes (see showFreeNodes()), or before the last row if there is such a line.

Parameters

line	The line to insert.
row	The row to insert the line into.
redraw	Indicates whether you want the manager and the grapher to redraw the invalidated area of the display.
layer	Specifies, if necessary, the layer where this object is to be inserted.

Reimplemented from IlvGanttChart.

§ makeView()

virtual void IlvGanttChartForm::makeView	(	IlvPort *	dst,

Parameters

dst	The port.
t	The transformer.

Reimplemented from IlvGanttChart.

§ moveSplitter()
