Method Detail

getLeadInImage

public nextapp.echo.ImageReference getLeadInImage(TabbedPane tp)

Description copied from interface: TabImageRenderer

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.

Specified by:

getLeadInImage in interface TabImageRenderer

Parameters:

tp - the TabbedPane in question

Returns:

the lead in image or null if there isnt one

See Also:

TabImageRenderer.getLeadInImage(echopoint.TabbedPane)

getLeadOutImage

public nextapp.echo.ImageReference getLeadOutImage(TabbedPane tp)

Description copied from interface: TabImageRenderer

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.

Specified by:

getLeadOutImage in interface TabImageRenderer

Parameters:

tp - the TabbedPane in question

Returns:

the lead out image or null if there isnt one

See Also:

TabImageRenderer.getLeadOutImage(echopoint.TabbedPane)

getTabImage

public nextapp.echo.ImageReference getTabImage(TabbedPane tp,
                                               int tabIndex,
                                               java.lang.String tabText,
                                               boolean isActive)

Description copied from interface: TabImageRenderer

This returns an ImageReference to be used as the tab's representation. This MUST NOT be null since the TabbedPane requires in image if a TabImageRenderer is in use.

Specified by:

getTabImage in interface TabImageRenderer

Parameters:

tp - the TabbedPane in question

tabIndex - - the index of the current tab

isActive - - true if the tab is active

Returns:

the image reference to use as the tab image

getInstance

public static DefaultTabImageRenderer getInstance(int tabPlacement)

This helper method will construct a DefaultTabImageRenderer with default colors of 0xC0C0C0 for the active tabs, 0xE0E0E0 for the inactive tabs and a border color of 0x000000. You need to specifiy the tab placement.

Parameters:

tabPlacement - - can be EchoConstants.TOP or EchoConstants.BOTTOM

Returns:

a primed DefaultTabImageRenderer

getInstance

public static DefaultTabImageRenderer getInstance(nextapp.echo.Color activeTabColor,
                                                  nextapp.echo.Color inactiveTabColor,

Parameters:

activeTabColor - - the desired active tab color

inactiveTabColor - - the desired inactive tab color

borderColor - - the desired border color

tabPlacement - - can be EchoConstants.TOP or EchoConstants.BOTTOM
