A few questions on Processing...

in Programming Questions • 1 year ago

Hi,

I just have a few questions on Processing and thought it would be best to to just throw them all in one post:

1: Is it possible to reference methods as variables like is done in JavaScript

i.e if(button.type=="close"){ button.action() = hide_parent(); }

2. Is there any way to read in pasted images (like is done in photoshop and similar programs?

3. is it possible to save a screenshot as an image file?

Thanks

1. No, not that I've ever seen.

2. Yes, but it is dark magic. See this.

3. Yes. See save(). Or if you want a screenshot of the whole screen (which is also dark magic), look into this. And the Robot class.

Thanks for the reply!

One more question:

4. I'm struggling with using showOpenDialog() when calling it from a button.

I have it in a void method called "open_file()".

If I call this method from setup it works fine but when I call it from clicking the button it gets stuck on the

int returnVal = fc.showOpenDialog(this); line

I have the method placed outside the button's class so the "this" is referring to the main parent

Any Ideas?

1) Not really, but there was a recent thread on how to do it in Java. BTW, string comparison isn't done with == in Java.
2) You already asked the question in a specific thread...
3) tfguy44 answered...
4) Don't mix Swing / AWT and Processing. See selectInput() or selectFolder() that correctly implement showOpenDialog().

Brilliant!

Didn't know about the selectInput() class!

Cheers
