Activate Keyboard Listener right after Applet load
Oct 21st, 2007, 9:25pm  
When I start the processing applet in PDE, I have to mouse click on the applet first, then the keyPressed() will start working.

If I don't mouse click once on the applet, keyboard event will not work. No matter i press on keyboard the Applet just don't get any events.

Any way I can start listen Keyboard event right after applet started?

I think that is a Focus problem you are having there.

I'm not verry familiar with that particular concept, but i've made a few applets and they usualy needed to be pressed once before they could receive keyboard input.

There are probably a few threads discussing that problem. Try to find something about focus, and try some soluction. Maybe your problem will be solved.

[edit] - but this section is probably the wrong place for you to ask or search this... but then again, no idea.

Also see this old blog post with a possible solution:

(just replace loop() with draw(), this was originally written for Processing ALPHA, still will work though...)
