Hello there. I’m writing an application in processing, and I want to change application’s default icon on the taskbar.
I know how this can be done by using surface.setIcon(PImage). But this doesn’t work when I’m using P3D, or P2D because I get this error:
But when I use PJOGL.setIcon(filename), the image never replaces the default application image with the image I want, despite it being in the sketch’s data folder (I don’t get any errors either). Is there any reason why this is happening?
EDIT: I am so sorry, I made a very silly mistake 
. I didn’t read the whole error. I managed to fix this by doing this:
void setup() {
}
void settings() {
size(100, 100, P3D);
PJOGL.setIcon("Sketch_Icon.png");
}
instead of this:
void setup() {
//PImage image = loadImage("Sketch_Icon.png","png");
size(500, 500, P3D);
PJOGL.setIcon("Sketch_Icon.png");
}
