1  Java Game APIs & Engines / JOGL Development / Refresh, restart JOGL on: 2004-10-23 00:35:16
I'm trying to write a simple molecule viewer with JOGL.  The first time I load a PDB file that contains the coordinate of the atoms,  instantiate the JOGL and add the GLCanvas to the content pane of a JFrame,  everything is working right. But when I use an JFileChooser to load another  molecule file,  nothing changes and when I resize the windows the canvas does not refresh correctly. The path to the file is correct.

I instantiate a new GLCanvas and a new Renderer class, that contains the display() method and implements the GLEventListner, and these problems with refresh occur.

I tried to reuse the GLCanvas I instantiated the first time, but  if I pass the molecule, with the coordinates to the Render class,  NullPointerException occurs.

Does anybody have any idea about this problem? Do I have to "refresh" the state of the OpenGL  to display something different from the moment of its creation, and if so, how do I do this "refresh"?
