*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
Rogue Wave Views Gantt had the following bugs that are now fixed:
*IlvGanttChart::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.
