Constructor Detail

ZBasicApplet

public ZBasicApplet()

Creates a new basic Jazz applet. It consists of a simple Jazz scenegraph mapped to a simple component in an applet. The scenegraph consists of a root, a node, and a camera that looks onto that node, plus a surface that is mapped to the window. Each of the scenegraph elements can be used via the accessor functions.

See Also:: getRoot(), getSurface(), getCamera(), getLayer()

Method Detail

init

public void init()

Overrides:: init in class java.applet.Applet

getCamera

public ZCamera getCamera()

Return the camera associated with the primary surface.

Returns:: the camera

getSurface

public ZSurface getSurface()

Return the surface.

Returns:: the surface

getRoot

public ZRootNode getRoot()

Return the root of the scenegraph.

Returns:: the root

getLayer

public ZNode getLayer()

Return the "layer". That is, the single node that the camera looks onto to start.

Returns:: the node

getComponent

public ZBasicComponent getComponent()

Return the component that the surface is attached to.

Returns:: the component

getPanEventHandler

public ZEventHandler getPanEventHandler()

Return the pan event handler.

Returns:: the pan event handler.

getZoomEventHandler

public ZEventHandler getZoomEventHandler()

Return the zoom event handler. *@eturn the zoom event handler.

activateEventHandlers

public void activateEventHandlers()

Activate the default event handlers for ZBasicFrame. This turns on basic panning and zooming event handlers for the mouse, so that the left button pans, and the right button zooms. If the event handlers are already activated, then this does nothing.

deactivateEventHandlers

public void deactivateEventHandlers()

Deactivate the default event handlers for ZBasicFrame. If the event handlers are already deactivated, then this does nothing.

setLookAndFeel

public void setLookAndFeel(int laf)

Set the Swing look and feel.

Parameters:: laf - The look and feel, can be WINDOWs_LAF, METAL_LAF, or MOTIF_LAF
