Processing – Present Mode Background Color

How to change the background color while running in Present Mode?

Add to setup() (NOTE: doesn’t work for Processing 3+!)

((javax.swing.JFrame) frame).getContentPane().setBackground(new java.awt.Color(0, 0, 0));

Alternative method (also Processing 3+!):

close Processing!
edit <user name>/Appdata/Roaming/Processing/preference.txt
make sure the run.present.bgcolor line looks like this:
run.present.bgcolor=#000000

This way you can make the window of a Processing sketch resizable

void setup() {
  size(400, 400);  // size always goes first!
  if (frame != null) {
    frame.setResizable(true);
  }
}
