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 resource table has three parts:

  1. 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.
  2. 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.
  3. 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.

endThe end time in the interval managed by the Gantt chart, given as an integer.
shownStartThe shown start time, given as an integer.
shownEndThe shown end time, given as an integer.
stepThe graduation step on all the Gantt chart views.
rowSizeThe initial width of the manager views.
lineInfoSizeThe width of user-defined regions.
unitSizeSpecifies the line-unit height and subnode height.
scaleHIndicates the scale height.
sbSizeSpecifies the height of the horizontal scroll bars and the width of the vertical scroll bars.
spacingIndicates the spacing between Gantt lines and the left, top, right, and bottom sides of the manager views.
vwSpacingIndicates the grapher view spacing.
marginSpecifies the spacing in pixels between the left, right, top, or bottom edge of Gantt chart and any scale, scroll bar, or view.
separSizeSpecifies 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.
hasScaleThis parameter is ignored. The scales are always on the top.
hasHSBThis parameter is ignored. The horizontal scroll bars are always at the bottom.
hasVSBThis parameter is ignored. The vertical scroll bars are always on the right.
numLayersIndicates the number of layers to be handled by the grapher.
useAccAn IlBoolean indicating whether the default accelerators are to be set (for a list of the default accelerators, see Table "Default manager and grapher accelerators").
paletteSpecifies 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 
)
virtual

Removes all the objects stored in the chart.

If the destroy parameter is set to IlTrue, the objects are destroyed. If this parameter is set to IlFalse, the objects are removed but not destroyed. In both cases, graphic objects are destroyed.

Parameters
destroySpecifies whether objects are destroyed after they are removed.
redrawSpecifies 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
areaThe 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
viewIndexValid 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
indexValid 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
lineThe line to insert.
rowThe row to insert the line into.
redrawIndicates whether you want the manager and the grapher to redraw the invalidated area of the display.
layerSpecifies, if necessary, the layer where this object is to be inserted.

Reimplemented from IlvGanttChart.

§ makeView()

virtual void IlvGanttChartForm::makeView ( IlvPort dst,
const IlvTransformer t 
)
virtual

Creates the views.

Creates the gadget container, the manager and the grapher, the two manager views, the four grapher views, and the scale objects.

Parameters
dstThe port.
tThe transformer.

Reimplemented from IlvGanttChart.

§ moveSplitter()

virtual void IlvGanttChartForm::moveSplitter ( IlvDirection  dir,
IlUInt  index,
IlvPos  pos 
)
virtual

Moves a splitter to a given position.

Moves the given splitter of the Gantt chart form to the position pos. It should not be called if the makeView method has not been called.
