Method Summary

Modifier and Type	Method and Description
void	draw(Graphics destination, IlvGanttGridContext context) Draws the grid to the specified Graphics in the specified IlvGanttGridContext.
Color	getForeground() Gets the grid foreground color.
Shape[]	getGridShapes(Graphics destination, boolean selection, IlvGanttGridContext context) Returns the grid shapes used to draw the grid in the specified context as an array of Shape.
void	setForeground(Color fg) Sets the grid foreground color.

Method Detail

draw

void draw(Graphics destination,
          IlvGanttGridContext context)

Draws the grid to the specified Graphics in the specified IlvGanttGridContext. To implement the method, you should take into account the clip of the specified Graphics and ensure not to draw the grid outside the clip in order to get a better performance.

Note that this method has been changed since Perforce JViews 5.0. The old method was draw(Graphics, IlvGanttSheet). In case you have overridden the old draw method, you have to rewrite your draw method in order to migrate to Perforce JViews 5.0. The benefit of using an IlvGanttGridContext instead of an IlvGanttSheet is that a different grid context can be provided while drawing the grid on screen and printing the grid on paper. The grid renderer becomes more flexible and can be used for both displaying on screen and printing on paper.

Parameters:

destination - The Graphics to which the grid draws.

context - The Gantt grid context used to draw the grid.

Since:

JViews 5.0

setForeground

void setForeground(Color fg)

Sets the grid foreground color.

Parameters:

fg - The new color.

getForeground

Color getForeground()

Gets the grid foreground color.

Returns:

The foreground Color.

getGridShapes

Shape[] getGridShapes(Graphics destination,
                      boolean selection,
                      IlvGanttGridContext context)

Returns the grid shapes used to draw the grid in the specified context as an array of Shape. Different shapes can be returned in case they are used for drawing the grid selection. For example, the shapes for drawing a grid could be rectangles, while the shapes for selecting it could be lines. The shapes are in the coordinates of the graphics context that is being drawn.

Parameters:

destination - The Graphics to draw into.

selection - If the shapes returned should be considered for drawing a selection.

context - The Gantt grid context.

Returns:

The array of transformed shapes representing the grid.

Since:

JViews 6.0
