Method Detail

getPreferredDrawingBounds

public org.eclipse.swt.graphics.Rectangle getPreferredDrawingBounds(org.eclipse.swt.graphics.Rectangle intervalDrawingArea,
                                                                    TimeBarViewerDelegate delegate,

Retrieve the preferred drawing bounds for a specific interval. Default implementation simply returns the intervalDrawingArea.

Specified by:

getPreferredDrawingBounds in interface TimeBarRenderer2

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

printing - true if rendering is done for a prinetr

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
