java 2 processing
Sep 5^th, 2008, 3:03pm

Hello,
I have got already a simulation written in java that use swing. If you click init button that appears a ball, then you can click the start button and the simulation will start. During the simulation you can click pause button and the simulation will make a pause. Additionally you can make a screenshot.

You can find the code here:

I didn't see a run() methode in processing. What I need to rewrite this code to processing?

Best regards

PhiLho

There is the mousePressed() event, which you can test against a region of the sketch area.
And you can use noLoop() to stop animation.
I added the following lines to the BouncyBubbles demo sketch:

boolean bMoving = true;

void mousePressed()
{
if (bMoving) noLoop();
else loop();
bMoving = !bMoving;
}

and it did the trick (pause/start).

How can I keep Swing buttons (with PhiLho solution) and exist something similar to BufferedImage so if I click on screenshot button I get a PNG picture of the simulation?

As I wrote, in Processing, the simplest method is to just draw a button and test the mousePressed() event against the region of the drawn button. I am not sure, but I think Swing and Processing doesn't mix well. That's probably why you have also a number of GUI libraries, which probably just draw controls and manage events on them. Although I think at least one of them use AWT or something like that (that Spring GUI, I checked some time ago because I want a text field accepting Windows paste operation, and I am not sure the other libraries accept it).

And to take a screenshot, it is very simple: you have the saveFrame() function!

BTW, that's the aim of Processing: being simpler than Java! While remaining powerful. And you can still tap on Java libraries whenever you need them.
