[Repast-interest] Possible bug / unclear usage in DisplayOGL2D

[Richard S. <js...@dm...>]

Hi,

 

I have a display that is an instance of DisplayOGL2D.  I also have a
class implementing ModelInitializer.  If I call the getPanel() method on
the DisplayOGL2D object, the display in question does not render for
some reason.  I realise this might be an unusual thing to do, but I want
to change the properties of one particular display programmatically on
initialisation (is there a better way to get hold of a display
programmatically?).  After a very long chase through the code, I think
the problem may be that the call to getPanel() creates a null panel
within the display. 



I have reproduced a small implementation to replicate the problem below
- in a context which just adds agents to a Network which is itself
displayed in a 2D display with all the Repast Simphony defaults.  Any
help if I'm doing something wrong much appreciated.

 

public class TestInitialiser implements ModelInitializer {

 

      @Override

      public void initialize(Scenario scen, RunEnvironmentBuilder
builder) {

            scen.addMasterControllerAction(new
NullAbstractControllerAction() {

 

                  //@Override

                  public void runInitialize(RunState runState, Context
context, Parameters runParams) {

 

 

                        List<IDisplay> listOfDisplays =
runState.getGUIRegistry().getDisplays();

                        for (IDisplay display : listOfDisplays) {

 

 
System.out.println(display.getClass().getName());

                              //having the line above is fine, but with
the line below, the display doesn't render

//If I comment out the following line the display renders OK. 

 
System.out.println(display.getPanel().getName());

                        };                      

                  }

            });

      }

}
