Method Detail

getRendererComponent

public javax.swing.JComponent getRendererComponent(TimeBarViewer tbv,
                                                   boolean top)

Return a JComponent to be used to render the time scale. The component has to be configured properly before returning it. All needed information about the time scale, major and minor ticks can be obtainend by the TimeBarViewer.

The component may implement getToolTipText(MouseEvent evt) to return a proper tooltip for the location

Specified by:

getRendererComponent in interface TimeScaleRenderer

Parameters:

tbv - the TimeBarViwer the component is used for

top - if true the scale is drawn at the top of the diagram

Returns:

a configured JComponent

getHeight

public int getHeight()

Return the height needed for painting the time scale. The value will be fetched only once when the renderer is set for the TimeBarViewer for reasons of stability in painting.

Specified by:

getHeight in interface TimeScaleRenderer

Returns:

the height of the time scale

initIterators

protected void initIterators()

Initialize all possible iterators (strips).

getMajorTicks

public java.util.List<de.jaret.util.date.JaretDate> getMajorTicks(TimeBarViewerDelegate delegate)

Provide a list of dates used as major ticks.

Specified by:

getMajorTicks in interface ITickProvider

Parameters:

delegate - the delegate the ticks are used with

Returns:

list of dates

getMinorTicks

public java.util.List<de.jaret.util.date.JaretDate> getMinorTicks(TimeBarViewerDelegate delegate)

Provide a list of dates used as minor ticks.

Specified by:

getMinorTicks in interface ITickProvider

Parameters:

delegate - the delegate the ticks are used with

Returns:

list of dates

setCorrectDST

public void setCorrectDST(boolean correctDST)

Setup the iterators to do a DST correction.

Parameters:

correctDST - true if a correction should be done.
