Method Detail

getLeadInImage

ImageReference getLeadInImage(TabbedPane tp)

This returns a "lead in" image that will be place to the left of all tab images. If there is no lead in image, then this method should return null.

Parameters:

tp - the TabbedPane in question

Returns:

the lead in image or null if there isnt one

getLeadOutImage

ImageReference getLeadOutImage(TabbedPane tp)

This returns a "lead out" image that will be place to the right of all tab images. If there is no lead out image, then this method should return null.

Parameters:

tp - the TabbedPane in question

Returns:

the lead out image or null if there isnt one

getTabImage

ImageReference getTabImage(TabbedPane tp,
                           int index,
                           Component tabComponent,
                           boolean isSelected)

This returns an ImageReference to be used as the tab's representation.

This MUST NOT be null since the TabbedPane requires an image if a TabImageRenderer is in use.

Parameters:

tp - the TabbedPane in question

index - - the index of the tab

tabComponent - - the component that represents the tab at index

isSelected - - true if the tab is the selected one
