You can access different groups of +demos by clicking the tabs at the top of the pane. There are demo +groups for Arcs_Curves, Clipping, Colors, Composite, Fonts, Images, +Lines, Mix, Paint, Paths and Transforms. On the right-hand side of the +pane, the GUI framework features individual and global controls for +changing graphics attributes. There's also a memory-usage monitor, and +a monitor for tracking the performance, in frames per second, of +animation demos. + + +----------------------------------------------------------------------- +Tips on usage +----------------------------------------------------------------------- + +Click on one of the tabs at the top of the pane to select a demo group. +When you select a group, a set of surfaces is displayed, each of which +contains one of the group's demos. At the bottom of each surface is +a set of tools for controlling the demo. The tools can be displayed +by selecting the Tools checkbox in the Global Controls panel or +by clicking on the slim strip of gray bumps at the bottom of the demo +panel. + +If you click on a demo surface, that demo is laid out by itself. A +new icon button will appear in the demo's tools toolbar one that enables +you to create new instances of that demo's surface. + +To run the demo continuously without user interaction, select the +Run Window item in the Options menu and press the run button in the +new window that's displayed. To do this from the command line: + + java -jar J2Ddemo.jar -runs=10 + +To view all the command line options for customizing demo runs: + + java -jar J2Ddemo.jar -help + +You can run the demos in stand-alone mode by issuing a command like this + + java -cp J2Ddemo.jar java2d.demos.Clipping.ClipAnim + +You can run the demos in groups by issuing a command like this + + java -cp J2Ddemo.jar java2d.DemoGroup Clipping + +To increase or decrease the Memory Monitor sampling rate click on the +Memory Monitor's title border, a panel with a TextField will appear. + +The J2Ddemo Intro (the 'J2D demo' tab) contains a scene table, click in +the gray border and a table will appear. + +Animated demos have a slider to control the animation rate. Bring up +the animated demo toolbar, then click in the gray area of the toolbar +panel, the toolbar goes away and the slider appears. + +Demos that have Custom Controls can have their Custom Control Thread +activated and stopped by clicking in the gray area of the demos Custom +Control panel. + +----------------------------------------------------------------------- +NOTE about demo surfaces +----------------------------------------------------------------------- + +The demo groups are in separate packages with their class files stored +in directories named according to the demo group name. All drawing +demos extend either the Surface, AnimatingSurface, ControlsSurface or +AnimatingControlsSurface classes. Surface is the base class, demos +must implement the Surface's render method. All animated demos extend +either the AnimatingSurface or the AnimatingControlsSurface classes. +Animated demos must implement the reset and step methods. The demos +with gui controls extend either the ControlsSurface or the +AnimatingControlsSurface classes. Demos with controls must implement +the methods in the CustomControlsContext interface. + + +====================================================================== + +Here are some resources for
