Class DefaultFontChooserModel

java.lang.Object

org.jhotdraw.gui.fontchooser.AbstractFontChooserModel

org.jhotdraw.gui.fontchooser.DefaultFontChooserModel

All Implemented Interfaces:

javax.swing.tree.TreeModel, FontChooserModel

Direct Known Subclasses:

DefaultFontChooserModel.UIResource

public class DefaultFontChooserModel
extends AbstractFontChooserModel

DefaultFontChooserModel with a predefined set of font collections.

Loading the fonts may take a lot of time. Therefore it is recommended to create a Future during the startup of an application, and set the fonts in the font chooser model when they are needed.

Example:

   private static FutureTask future = new FutureTask(new Callable() {

      public Font[] call() throws Exception {
          return GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();

       }
   });
