passing parameters in shell
« on: Jul 10th, 2004, 10:06pm »

hello
 
i am searching for a way to pass parameters like width and height or the location of an image to a processing applet in the shell. is there a way?
 
adding it to BApplet would be easy. but i do not know how to pass a parameter to "applet" does not work.
 
i defined a String [] parameter in my project. in BApplet i can not assign applet.parameter = ...;
 
BApplet
...
Frame frame = new Frame();
   Class c = Class.forName(args[0]);
   BApplet applet = (BApplet) c.newInstance();
   applet.init();
   applet.start();
   applet.parameter = args[0];
...
 
 
my project
...
public class overlays02 extends BApplet{
 
 // screenWidth, screenHeight, mode, backGround, imageLoc
 String [] parameters = new String [5];
...

hi michael,
 
once you cast back to BApplet in line:
 
BApplet applet = (BApplet) c.newInstance();
 
you will lose your parameters variable ... maybe try this: extend BApplet with just that variable (say as BAppletP), then extend BAppletP with your project-classes. see link ...
