java.lang.Object
  org.jdesktop.swingx.renderer.DefaultVisuals<T>

All Implemented Interfaces:

java.io.Serializable

public class DefaultVisuals<T extends javax.swing.JComponent>
extends java.lang.Object
implements java.io.Serializable

Encapsulates the default visual configuration of renderering components, respecting the state of the passed-in CellContext. It's basically re-usable across all types of renderees (JTable, JList, JTree).

Guarantees to completely configure the default visual properties (listed below) of a given component. As a consequence, client code (f.i. in Highlighters) can safely change them without long-lasting visual artefacts.

• foreground and background, depending on selected and focused state
• border
• font
• Painter (if applicable)
• enabled
• componentOrientation
• toolTipText
• minimum-, maximum-, preferredSize

Client code will rarely need to be aware of this class. It's the single place to change on introduction of new properties considered as belonging to the "default visuals" of rendering components.

PENDING: allow mutators for overruling the CellContexts defaults? Would prefer not to, as in the context of SwingX visual config on the renderer level is discouraged (the way to go are Highlighters.

PENDING: not yet quite decided whether the toolTipText property belongs into the visual default config. Doing so gives client code the choice to set it either in a Highlighter or a custom ComponentProvider.

public DefaultVisuals()

Method Detail

setForeground

public void setForeground(java.awt.Color c)

Sets the renderer's unselected-foreground color to the specified color. If not null this color will overrule the default color of the CellContext.

Parameters:

c - set the foreground color to this value

setBackground

public void setBackground(java.awt.Color c)

Sets the renderer's unselected-background color to the specified color. If not null this color will overrule the default color of the CellContext.

Parameters:

c - set the background color to this value

configureVisuals

public void configureVisuals(T renderingComponent,
                             CellContext context)

Configures all default visual state of the rendering component from the given cell context.

Parameters:

renderingComponent - the component to configure, must not be null

context - the cell context to configure from, must not be null

Throws:

java.lang.NullPointerException - if either renderingComponent or cellContext is null
