public LwjglLayerRenderer(Layer layer_to_render,
                          LayerViewGLPanel theLayerViewPanel)

Constructor of renderer using a Layer and a LayerViewPanel.

Parameters:

theLayer - a layer to render

theLayerViewPanel - the panel to draws into

Method Detail

setLayerViewPanel

public void setLayerViewPanel(LayerViewGLPanel layerViewPanel)

Parameters:

layerViewPanel - the layerViewPanel to set

getLayerViewPanel

public LayerViewGLPanel getLayerViewPanel()

Specified by:

getLayerViewPanel in interface LayerRenderer

addActionListener

public void addActionListener(ActionListener l)

Adds an ActionListener.

Specified by:

addActionListener in interface LayerRenderer

Overrides:

addActionListener in class AbstractLayerRenderer

Parameters:

l - the ActionListener to be added

Specified by:

createRunnable in interface LayerRenderer

Returns:

a new runnable
