A way to disable the ESC key behavior of quiting a sketch

[villares]

In Processing Python mode I have seen some examples with code like this:

def keyPressed():
    if key == ESC:
        # do whatever you want ESC to trigger
        this.key = ' '  # this would allow the sketch to continue running

But that doesn't work on py5 as the current sketch object, obtained with get_current_sketch(), won't allow fiddling with the key attribute. Any suggestions?

Interesting. I looked at the Processing source code and I see the comments specifically mention setting key to something else:

...
    // if someone else wants to intercept the key, they should
    // set key to zero (or something besides the ESC).
    if (event.getAction() == KeyEvent.PRESS) {
      //if (key == java.awt.event.KeyEvent.VK_ESCAPE) {
      if (key == ESC) {
        exit();
      }
...

I agree that what you are doing should be possible. I can't think of a way to do this without making the key property settable. This is certainly possible. Normally the properties are read only. Perhaps in Processing you can fiddle with variables like width and height but I don't think allowing this is a good idea. Allowing key to be modified makes sense though.

The alternative is to have some special set_key() method, but that seems weird and awkward to me, and totally different from how Processing works.

I'll open an issue for this so I don't forget about it. It won't be in tomorrow's release but it will be in the next release after that one.

The issue about this was #549, a fix to be released soon!
