Constructor Detail

PjCurvature

public PjCurvature()

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

getSphereDisplay

public PvDisplayIf getSphereDisplay()

start

public void start()

Description copied from class: PjProject

Method is invoked during loading of a project in JavaView.

If a project has an animation object, then the animation panel is shown when the project's this start() method is invoked during loading of the project. Use setAnimation(PsAnimation) to register an animation.

If auto fit is enabled then scenery is scaled to fit in each display.

Overrides:

start in class PjProject

See Also:

PvViewerIf.start(), PjProject.isEnabledAutoFit()

stop

public void stop()

Description copied from class: PjProject

Stop all animations and auto-rotation in display. Hide animation panel, remove itself as pick listener from displays. The object can be reinvoked using init() and start().

Overrides:

stop in class PjProject

See Also:

PvViewerIf.stop()

setTime

public boolean setTime(PsTimeEvent ev)

Description copied from class: PjProject

Empty method, must be overwritten by subclasses to update dynamic object.

Specified by:

setTime in interface PsTimeListenerIf

Overrides:

setTime in class PjProject

pickInitial

public void pickInitial(PvPickEvent p)

Description copied from class: PjProject

Pick an arbitrary point on a geometry, point may lie inside an element. This method does nothing and must be overwritten.

Specified by:

pickInitial in interface PvPickListenerIf

Overrides:

pickInitial in class PjProject

Parameters:

p - Pick event issued by the display

See Also:

PvPickListenerIf

endPicking

public void endPicking()

update

public boolean update(java.lang.Object o)

Description copied from class: PsObject

Update all inspector panels, send update to all registered update listeners and finally update parent. Each of those updates has this object as event independent of the argument of this method.

Central update method of this object. Must be overwritten if this class receives unknown events, say, from new children. Any subclass must class invoke super.update(event) on all events it does handle itself.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

o - carries a lot of information

Returns:

true if event has been handled, otherwise false
