PaDisplayOverlay

public PaDisplayOverlay()

Method Detail

getAppletInfo

public java.lang.String getAppletInfo()

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

Specified by:

getAppletInfo in class PvApplet

getSizeOfFrame

public java.awt.Rectangle getSizeOfFrame()

Return a new allocated project instance.

Overrides:

getSizeOfFrame in class PvApplet

getProject

public PjProject getProject()

Return a new allocated project instance.

Specified by:

getProject in class PvApplet

run

public void run()

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

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class PvApplet

getFather

public PsUpdateIf getFather()

Get parent and do nothing else.

Historical note: previous to Java 1.1 this method was called getParent() in JavaView, but in Java 1.1 a method with same name was introduced in java.awt.Component which prevented us to continue to this method in any of our subclasses of AWT components. In order to be consistent, the JavaView method getParent() was replaced with getFather() everywhere. Since that time JavaView uses the pair setParent/getFather, and lives quite well with that.

Specified by:

getFather in interface PsUpdateIf

See Also:

setParent(jv.object.PsUpdateIf), update(Object)

setParent

public void setParent(PsUpdateIf parent)

Set parent and do nothing else. Method is implemented by PsObject and PsPanel, and should be called if overwritten.

Specified by:

setParent in interface PsUpdateIf

Parameters:

parent - will receive events which this does not handle

See Also:

getFather(), update(Object)

update

public boolean update(java.lang.Object event)

Event handling method in the update mechanism. Events not handled will be passed to m_parent or super in this sequence.

Specified by:

update in interface PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

PsObject, getFather(), setParent(jv.object.PsUpdateIf)

main

public static void main(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.
