Operating system

MacOSX

Steps to reproduce this

Likely a bug with Safari/DOM, but worth seeing if something could be resolved from within p5js code. When creating a dropdown DOM with createSelect() function in p5js, it seems that on Safari, interactions with that dropdown are triggering a p5js mousePressed event but not a corresponding p5js mouseReleased event. This leaves internal variable mouseIsPressed set to true, and subsequent mouse move events are being categorized as mouse draw events from within src/events/mouse.js as a result. Problem was reproduced on two machines using MacOSX + Safari, but the problem does not occur when using Chrome or Firefox on those same machines, nor when using Safari on an iPad.

Steps:

  1. Click on the dropdown widget to make selection
  2. Release mouse after making selection
  3. Mouse over the p5js Canvas.

Snippet:


// Demo at https://editor.p5js.org/michaelgoldwasser/sketches/Dbdib65Qp
function setup() {
  createCanvas(400, 400);
  background(220);
  noStroke();
  selector = createSelect();
  selector.option("red", color(255, 0, 0));
  selector.option("blue", color(0, 0, 255));
}

function mousePressed() {
  console.log("mousePressed fired");
}

function mouseReleased() {
  console.log("mouseReleased fired");
}

function mouseDragged() {
  fill(selector.value());
  circle(mouseX, mouseY, 5);
}
