Class PrintUtilities

java.lang.Object
  org.virion.jam.util.PrintUtilities

All Implemented Interfaces:

Printable

public class PrintUtilities
extends Object
implements Printable

A simple utility class that lets you very simply print an arbitrary component. Just pass the component to the PrintUtilities.printComponent. The component you want to print doesn't need a print method and doesn't have to implement any interface or do anything special at all.

If you are going to be printing many times, it is marginally more efficient to first do the following:

 PrintUtilities printHelper = new PrintUtilities(theComponent);
 

then later do printHelper.print(). But this is a very tiny difference, so in most cases just do the simpler PrintUtilities.printComponent(componentToBePrinted).

disableDoubleBuffering

public static void disableDoubleBuffering(Component c)

The speed and quality of printing suffers dramatically if any of the containers have double buffering turned on. So this turns if off globally.

enableDoubleBuffering

public static void enableDoubleBuffering(Component c)

Re-enables double buffering globally.
