• IlvGanttLineGrid

• IlvGanttLineReliefGrid

• IlvGanttResourceGrid

• IlvGanttRowGrid

• IlvGanttCalendarGrid

IlvGanttChart has the following new public methods:

• IlvPalette* getGridPalette();

• void setGridPalette(IlvPalette*);

• IlBoolean isDrawingGrapherViewBorders();

• void setDrawingGrapherViewBorders(IlBoolean);

• IlSymbol* WorkAreaCallbackType();

• IlvRect& getWorkArea(IlvRect& area);

• IlvRect& getLineArea(IlvRect& area);

• IlvGraphic* setLineGrid(IlvGraphic* grid, IlvBoolean redraw, IlInt layer);

• IlvGraphic* getLineGrid();

• IlvGraphic* setRowGrid(IlvGraphic* grid, IlvBoolean redraw, IlInt layer);

• IlvGraphic* getRowGrid() const;

• void setDoubleBuffering(IlBoolean);

• IlBoolean isDoubleBuffering() const;

Incompatibilities

The signatures of the following methods of IlvGanttChartForm have been changed:

• IlvGraphic* setCompositeScale(IlvGraphic*, IlBoolean, IlBoolean);

• IlvGraphic* getCompositeScale() const;

• IlvGraphic* setCompositeGrid(IlvGraphic*, IlvBoolean);

• IlvGraphic* getCompositeGrid() const;

Behavior Changes

IlvGanttChart::rowResized(IlvUShort, IlvPos) calls the new “Work Area” callback.

The default layer for the Gantt lines is changed from 0 to 1.

• void addLine(IlvGanttLine* line, IlBoolean redraw,int layer=1);

• void insertLine(IlvGanttLine* line, IlUShort row, IlBoolean redraw, int layer=1);

Deprecated Methods

IlvGanttChartForm::setCompositeGrid() is deprecated. Use IlvGanttChart::setRowGrid() instead.

Samples

In the sample folder of the Gantt module, <ILVHOME>/samples/gantt, the load and month samples are considerably revised. Two new samples, simple and calendar, are added.

Bug Fixes

Views Gantt had the following bugs that are now fixed:

• psDump dumping the grids of the grapher views.

• The IlvGanttChart could not be properly resized before it was added to a container.

• IlvGanttChart could not switch to mono view interactively by dragging the handle between the grapher views.
