using thinlets with processing
Dec 31st, 2005, 4:52pm  
Hi,


this is a fast hack to show how to use thinlets
with processing. there are many GUI related posts on this
forums, so i thought sharing this even if its nothing
special.

for a demo see:
http://rzserv2.fhnon.de/~lg016586/processing/ThinletDemo/index.html

the project as package:
http://rzserv2.fhnon.de/~lg016586/processing/ThinletDemo/ThinletDemo-001.zip

and the library (even if it is not a real library; just the
thinlet jar):
http://rzserv2.fhnon.de/~lg016586/processing/ThinletDemo/libraries.zip

as mentioned, nothing special, but maybe helpful for someone else.

Last I recall, thinlet didn't do mouse event translation to custom widgets, so if you wanted to have any kind of direct interaction with the processing display a little more work needs to be done.

To get that working (although I haven't done this with processing, just thinlet+custom render display) I had to hack up thinlet a bit and a real "Widget" object.  It was pretty rudimentary, though, and only supported certain mouse input via a custom method:
Code:
public void handleMouseEvent(int x, int y, int clickcount,
		boolean shiftdown, boolean controldown, boolean popuptrigger,
		int id)


So I suggest that anyone interested in working with thinlet and processing take a little time to see how that works.

yes you're right. handling mouse and key events is a bit
more difficult. i haven't tested the events with thinlets
and processing, but passing the events from thinlet to
the PApplet should work with an simple eventhandler method
in the custom PThinlet. maybe something like:
Code:

protected void processEvent(AWTEvent e) {

  super.processEvent(e);
  if (e instanceof KeyEvent) {
    parent.keyEvent = (KeyEvent) e;
    parent.key = ((KeyEvent) e).getKeyChar();
    parent.keyCode = ((KeyEvent) e).getKeyCode();

    switch (e.getID()) {
    case KeyEvent.KEY_PRESSED:
	     parent.keyPressed((KeyEvent) e);
	     break;
    case KeyEvent.KEY_RELEASED:
	     parent.keyReleased((KeyEvent) e);
	     break;
    case KeyEvent.KEY_TYPED:
	     parent.keyTyped((KeyEvent) e);
	     break;
    }
  }
}
