App Icon Processing 4

Processing Coding Questions
1

I’m trying to set the icon for the application (and in the task bar) in Processing4, and I have this:

  PImage icon = loadImage("icon.png");
  surface.setIcon(icon);

The image is 778x758; it doesn’t show up though in the program or task bar, so I’m not sure what to do here as this is the documentation:
https://processing.github.io/processing-javadocs/core/processing/core/PSurface.html#setIcon-processing.core.PImage-

Update, I’m using P2D and it appears to work for JAVA2D , however, it’s far too laggy for my image intense program and I need to use P2D… so, still not sure of the solution, but it appears that P2D is the issue here?

hi @Edenstudent,

there are restrictions on setting an icon for JOGL context and therefore it needs to be setup in settings instead of setup method…

Try this…

void settings() {
  size(500,500,P2D);
  PJOGL.setIcon(dataPath("icon.png"));
}

usually if you do this…

void setup() {
    size(500,500,P2D);
    surface.setIcon(loadImage("icon.png"));
}

… you should see an error message like below in the console output !?

Window icons for OpenGL sketches can only be set in settings()
using PJOGL.setIcon(filename).

Awesome, thanks so much, this worked perfectly!
And no, it didn’t throw any errors or warnings, just did nothing.

Hello @Edenstudent,

This is what I see with Processing 4.3 on W10:

Setting icon in settings():

How cool is that!

Oh, my mistake; I thought you meant warning in the errors list, not the console. It fills up so quickly when starting that I must’ve missed it, sorry
