Typing some characters in P2D won't return what character was pressed with keyPressed in Processing 4.3

Created by: bugreporter0

Description

Expected Behavior

"< was pressed" should be written in the console

Current Behavior

keyPressed detects that a character was typed but not which one when "<" is typed

Steps to Reproduce

Works:

void setup()
{
  size(400, 400);
}

void draw()
{
}

void keyPressed()
{
  if(key == '<')
    println("< was pressed");
}

Doesn't work:

void setup()
{
  size(400, 400, P2D);
}

void draw()
{
}

void keyPressed()
{
  if(key == '<')
    println("< was pressed");
}

Your Environment

• Processing version: 4.3
• Operating System and OS version: both windows (10, 11) and Ubuntu 22.04
• Other information:

Possible Causes / Solutions

Maybe some characters have been forgotten in the keyPressed P2D API in Processing 4 and above because it worked in the last Processing 3 version, I've checked

I'm sorry for the weird behavior, I'm new to GitHub and I don't know English very well

@bugreporter0 What is the key combination you have to press to get the < character on your OS's?

I'm bugreporter0.

My keyboard has this character as a key, it's a standard AZERTY full size keyboard. The "<" character is next to the left SHIFT key.

"<" is not the only missing character, it's just an example.

Hi @pinkandwhiteandblack

The keyPressed documentation page includes this note:

For non-ASCII keys, use the keyCode variable.

See https://processing.org/reference/keyPressed_.html

You can find the key code for any key by using a tool like https://www.toptal.com/developers/keycode

[pinkandwhiteandblack]

The keyCode variable should be set to 60 when I press "<" but println(keyCode) prints "0" in the console when I do, confirming that there really is a problem.

Code:

void setup()
{
  size(400, 400, P2D);
}

void draw()
{
}

void keyPressed()
{
  println(keyCode);
}

Important: it works in the default render (with keyCode 153 instead of 60 but whatever) but not in P2D.

Also, the"Alt Gr" key on my keyboard returns two keyCodes: 17 then 18 when I press it just once.

Worth checking if this is fixed by #966 (cc @Rishab87)

If not, this could be a test too :)

[Rishab87]

Yes it is also fixed by #966

[SableRaf]

Great! Thanks @Rishab87 ✨

The issue is still present in 4.4.4 on Windows 10

[SableRaf]

Hi @pinkandwhiteandblack

Just tested this on Windows 10 with a QWERTY keyboard using Processing 4.4.4. Pressing < works as expected in P2D.

I don’t have access to an AZERTY keyboard right now, so I can’t test that setup directly.

To help us narrow this down, could you share a few more details?

• Your keyboard layout and language
• The key combo you press to get “<”
• Any input method or keyboard remapping tools you're using
• The full sketch you're running (if it's different from the one in the original post)

If it turns out to be layout-specific, we can reopen this or open a new issue with those details.

[pinkandwhiteandblack]

• This layout in french, the key is between "left shift" and "W".
• I'm not using any remapping tool
• This sketch (the original):

void setup()
{
  size(400, 400, P2D);
}

void draw()
{
}

void keyPressed()
{
  if(key == '<')
    println("< was pressed");
}

It's probably layout-specific because it works when I use a QWERTY keyboard.
