[Solved][Scene2D] TextField, backspace

Newbie & Debugging Questions
#1

So I have 2 text fields for a username and password.

All works as expected, however…how the hell do I detect when the backspace key is pressed? Is there a character ID/unicode for this?

Atm I have this:

		username = new TextField("", style);
		username.setTextFieldListener(new TextFieldListener() {
			
			
			@Override
			public void keyTyped(TextField textField, char c) {
				usernameString.append(Character.toUpperCase(c));
				textField.setText(usernameString.toString());
			}
		});

I am using a Stringbuilder for it, basically when backspace is entered I want to delete the character at the last index of the string. Any ideas?

Surely I don’t have to run a separate check for this? As in:

Gdx.input.isKeyPressed(Keys.BACKSPACE);
