Method Detail

getTimeBarRendererComponent

public javax.swing.JComponent getTimeBarRendererComponent(TimeBarViewer tbv,
                                                          de.jaret.util.date.Interval value,
                                                          boolean isSelected,
                                                          boolean overlapping)

Supply a component to render an interval in the TimeBarViewer. The component may

• implement contains(x,y) for exact selection and tooltip firing
• put the containing rectangle in the client property TimeBarRenderer.CONTAINING_RECTANGLE for exact selection using the selection rectangle

Specified by:

getTimeBarRendererComponent in interface TimeBarRenderer

Parameters:

tbv - the asking TimeBarViewer

value - the interval to render

isSelected - render marked as selected

overlapping - true if the interval is one of an overlapping set of intervals

Returns:

a configured JComponent, ready to be painted by paint(Graphics g)

defaultGetTimeBarRendererComponent

public javax.swing.JComponent defaultGetTimeBarRendererComponent(TimeBarViewer tbv,
                                                                 de.jaret.util.date.Interval value,
                                                                 boolean isSelected,
                                                                 boolean overlapping)

getPreferredDrawingBounds

public java.awt.Rectangle getPreferredDrawingBounds(java.awt.Rectangle intervalDrawingArea,
                                                    TimeBarViewerDelegate delegate,
                                                    de.jaret.util.date.Interval interval,
                                                    boolean selected,
                                                    boolean overlap)

Retrieve the preferred drawing bounds for a specific interval. As a default implementation simply return the interval drawing area. Simple default implementation.

Specified by:

getPreferredDrawingBounds in interface TimeBarRenderer

Parameters:

intervalDrawingArea - the rectangle to render the interval in.

delegate - the viewer delegate

interval - the interval to be rendered

selected - true if the interval is selected

overlap - true if the interval is drawn as one of several intervals that overlap while beeing drawn.

Returns:

the bounding rectangle that the renderer will paint in when rendering
