pre and draw functions aren't working
May 26th, 2010, 3:34am  
Hi,

my pre() and draw() functions in the library aren't working. I don't know why. I can invoke the functions manually from the sketch, but they aren't invoked by processing.

Also I can't check implementations of my EventDispatches with the technique described at http://dev.processing.org/libraries/basics.html .

I uploaded the distribution to http://github.com/csteinlehner/katerLibDev/downloads you can also checkout the project from there.

If somebody can help I would be really be thankful, I can't see the missing part in my code.

Christoph

ok, sorry I forgot to register pre and draw with my parent PApplet.

It should be included in the library example.

Is there a similar thing for the EventRegistration?

These methods are also available
Quote:
public void mouseEvent(MouseEvent e)
Called when a mouse event occurs in the parent applet. Drawing is allowed because mouse events are queued.


public void keyEvent(KeyEvent e)
Called when a key event occurs in the parent applet. Drawing is allowed because key events are queued.


Look at http://dev.processing.org/libraries/basics.html for more info.

Oh and don't forget to register them  Wink
