Class IlvHorizontalGanttGrid

java.lang.Object

ilog.views.gantt.graphic.grid.IlvAbstractGanttGrid

ilog.views.gantt.graphic.grid.IlvHorizontalGanttGrid

All Implemented Interfaces:

IlvGanttGridRenderer

public class IlvHorizontalGanttGrid
extends IlvAbstractGanttGrid

An IlvHorizontalGanttGrid draws a horizontal grid for a Gantt sheet.

The grid can be set to two working modes:

• Line mode - The grid draws only horizontal lines and the rows of the Gantt sheet are not filled.
• Filled mode - The grid draws horizontal lines and also fills the rows of the Gantt sheet. The odd rows and the even rows are filled with different background colors.

Constructor Detail

IlvHorizontalGanttGrid

public IlvHorizontalGanttGrid()

Creates a new IlvHorizontalGanttGrid.

Method Detail

isFilled

public boolean isFilled()

Indicates whether the grid should be filled.

Returns:

Whether the grid should be filled.

See Also:

setFilled(boolean)

setFilled

public void setFilled(boolean filled)

Defines whether the grid should be filled.

Parameters:

filled - true if the grid should be filled.

setFilled(boolean)

draw

public void draw(Graphics dst,
                 IlvGanttGridContext context)

Draws the horizontal grid in the specified Gantt grid context.

Note that this method has been changed since 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 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 the screen and printing the grid on the paper. The grid renderer becomes more flexible and can be used for both displaying on screen and printing on paper.

Parameters:

dst - The Graphics into which the grid will be drawn.

context - The Gantt grid context.

Since:

JViews 5.0

getGridShapes

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

Returns the grid shapes used to draw the grid in the specified context as an array of Shape. This implementation returns an array of Line2D.Double for drawing the selection, and an array of Line2D.Double and Rectangle2D.Double for drawing successively the lines and the background rectangles. The shapes are in the coordinates of the graphics context that is being drawn.

Parameters:

dst - 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

setOddRowsBackground

public void setOddRowsBackground(Color bg)

Sets the background color of odd rows.

Parameters:

bg - The new color.

Sets the background color of even rows.

Parameters:

bg - The new color.
