Constructor Detail

ImageDataValueRenderer

public ImageDataValueRenderer(String name)

Create new renderer.

Parameters:

name - Name of the renderer, e.g. "PNG Image".

Method Detail

setValue

protected void setValue(Object value)

Sets the object to be rendered next. This method is invoked from the AbstractPainterDataValueRenderer.getRendererComponent(Object), AbstractPainterDataValueRenderer.getTableCellRendererComponent( JTable, Object, boolean, boolean, int, int), and AbstractPainterDataValueRenderer.getListCellRendererComponent( JList, Object, int, boolean, boolean) methods.

Specified by:

setValue in class AbstractPainterDataValueRenderer

Parameters:

value - The value to render. This is most of the time a DataValue that the derived class is supposed to render. However, it may also be null, a missing data cell or any other object.

getDescription

public String getDescription()

Get a description for this renderer implementation. It will serve to identify this renderer when the user has the choice of different renderer that are available. Make sure that this description is likely to be unique (if not only one of renderer with this ID is shown as available) and this description is short but "expressive" so that it can be shown as label in menus, for instance.

Specified by:

getDescription in interface DataValueRenderer

Overrides:

getDescription in class AbstractPainterDataValueRenderer

Returns:

"Default"

See Also:

DataValueRenderer.getDescription()

paintComponent

protected void paintComponent(Graphics g)

Overrides:

paintComponent in class JComponent

getPreferredSize

public Dimension getPreferredSize()

Get the dimension which the renderer component will preferably occupy.

Specified by:

getPreferredSize in interface DataValueRenderer

Overrides:

getPreferredSize in class JComponent

Returns:

Size of the component being rendered.
