Interface ILspViewListener

All Known Implementing Classes:

ALspViewAdapter

public interface ILspViewListener

Listener that can be added to an ILspView to be informed of initialization, dispose and render events. The methods of this interface are invoked as follows:

• postInit(com.luciad.view.lightspeed.ILspView, com.luciad.view.opengl.binding.ILcdGLDrawable): when the view's OpenGL context is initialized. Typically this is when the view is repainted for the first time.
• preDispose(com.luciad.view.lightspeed.ILspView, com.luciad.view.opengl.binding.ILcdGLDrawable): when the view is destroyed.
• preRender(com.luciad.view.lightspeed.ILspView, com.luciad.view.opengl.binding.ILcdGLDrawable) and postRender(com.luciad.view.lightspeed.ILspView, com.luciad.view.opengl.binding.ILcdGLDrawable): at the start and end of each repaint of the view.
• prePaintPhase(com.luciad.view.lightspeed.ILspView, com.luciad.view.opengl.binding.ILcdGLDrawable, com.luciad.view.lightspeed.TLspPaintPhase) and postPaintPhase(com.luciad.view.lightspeed.ILspView, com.luciad.view.opengl.binding.ILcdGLDrawable, com.luciad.view.lightspeed.TLspPaintPhase): during the repaint of the view, between the calls to preRender and postRender. Each pair of calls bounds the handling of a TLspPaintPhase. Depending on the view's current settings, each repaint may contain more than one paint phase.

Method Details

postInit

void postInit(ILspView aView,
 ILcdGLDrawable aGLDrawable)

Called after the view is initialized to initialize this listener.

Parameters:

aView - the view this listener belongs to

aGLDrawable -

preDispose

void preDispose(ILspView aView,
 ILcdGLDrawable aGLDrawable)

Called before the view is disposed to dispose of any resources held by this listener.

Parameters:

aView - the view this listener belongs to

aGLDrawable -

preRender

void preRender(ILspView aView,
 ILcdGLDrawable aGLDrawable)

Called before the view's layers are rendered.

Parameters:

aView - the view this listener belongs to

aGLDrawable -

prePaintPhase

void prePaintPhase(ILspView aView,
 ILcdGLDrawable aGLDrawable,
 TLspPaintPhase aPhase)

Called before the view's layers are painted for the given paint phase.

The paint pass indicates whether transparent or opaque objects should be painted, whether objects to be draped or not should be painted, etc. To ensure correct results and to avoid painting multiple times, it is important to consult this mode and to only paint when the proper paint pass is passed.

Parameters:

aView - the view this listener belongs to

aGLDrawable -

aPhase - the phase that is currently painted

postPaintPhase

void postPaintPhase(ILspView aView,
 ILcdGLDrawable aGLDrawable,
 TLspPaintPhase aPhase)

Called after the view's layers are painted for the given paint phase.

The paint phase indicates whether transparent or opaque objects should be painted, whether objects to be draped or not should be painted, etc. To ensure correct results and to avoid painting multiple times, it is important to consult this mode and to only paint when the proper paint phase is passed.

Parameters:

aView - the view this listener belongs to

aGLDrawable -

aPhase - the phase that is currently painted

postRender

void postRender(ILspView aView,
 ILcdGLDrawable aGLDrawable)

Called after the view's layers are rendered.

Parameters:

aView - the view this listener belongs to

aGLDrawable -
