Interface TimeBarGapRenderer

All Known Implementing Classes:

DefaultGapRenderer

public interface TimeBarGapRenderer

Interface for supplying a JComponent for rendering the gaps between two intervals. The supplied JComponent should be reused and only be set up for rendering a single gap. Setup is done by the TimeBarViewer. Since in some situations the gap betwwen two intervals is very small (or non-existent) it is possible to enforce a minimum width for the clipping rect and size for the gap rendering component.

Method Summary

int	getMinimumWidth() By returning a non negative value a minimum width will be given to the renderer.
javax.swing.JComponent	getTimeBarGapRendererComponent(TimeBarViewer tbv, TimeBarRow row, de.jaret.util.date.Interval interval1, de.jaret.util.date.Interval interval2)

Method Detail

getTimeBarGapRendererComponent

javax.swing.JComponent getTimeBarGapRendererComponent(TimeBarViewer tbv,
                                                      TimeBarRow row,
                                                      de.jaret.util.date.Interval interval1,
                                                      de.jaret.util.date.Interval interval2)

Parameters:

tbv - the calling TimeBarViewer

row - the row the intervals are in

interval1 - left interval (may be null if the gap is the starting "gap")

interval2 - right interval (may be null if it is the ending "gap")

Returns:

a configured JComponent for rendering

getMinimumWidth

int getMinimumWidth()

By returning a non negative value a minimum width will be given to the renderer. The size and clipping rect will be centered around the middle of the gap between the two intervals.

Returns:

minimum width for the rendering component. A negative value indicates no need for a fixed minimum width
