Constructor Detail

PvApplet

public PvApplet()

Method Detail

getAppletInfo

public abstract java.lang.String getAppletInfo()

Interface of applet to inform about author, version, and copyright

Overrides:

getAppletInfo in class java.applet.Applet

getProject

public abstract PjProject getProject()

Return a new allocated project instance.

getSizeOfFrame

public java.awt.Rectangle getSizeOfFrame()

Return default position and size of applet frame.

init

public void init()

Create thread that configures and initializes the viewer, loads system and user projects.

Overrides:

init in class java.applet.Applet

run

public void run()

Configure and initialize the viewer, load system and user projects. One of the user projects may be selected here.

Specified by:

run in interface java.lang.Runnable

main

public static void main(PvApplet va,
                        java.lang.String[] args)

Standalone application support. The main() method acts as the applet's entry point when it is run as a standalone application. It is ignored if the applet is run from within an HTML page.

Version:

24.03.11, 2.00 revised (kp) Set bounds of frame already before applet is initialized.

getViewer

public PvViewerIf getViewer()

Get viewer manager.

getDisplay

public PvDisplayIf getDisplay()

Get main display.

drawMessage

public void drawMessage(java.lang.String message)

Set message string to be drawn in applet while loading.

paint

public void paint(java.awt.Graphics g)

Print info while initializing applet and viewer.

Overrides:

paint in class java.awt.Container

destroy

public void destroy()

Does clean-up when applet is destroyed by the browser. Here we just close and dispose all our control windows.

Overrides:

destroy in class java.applet.Applet

stop

public void stop()

Stop viewer, e.g. stop animation if requested

Overrides:

stop in class java.applet.Applet

startFromThread

public void startFromThread()

Start viewer, e.g. start animation if requested. Necessary, if initialization is done in a separate thread. In this case the original applet.start() has no effect.
