hi there !
In the processing handbook is an example for an
extremely minimal text editor, that can only insert and remove characters from a single line.
I want to have one with more than one line. So I tried a bit around
and endet with
if (key==RETURN){}
in the last line, which works,
but the first thing is:
i don´t know why it works
(because the if clause is empty here)
and second:
there has to be a cleaner more complicatet solution.
thanks for your help!



PFont font;
String letters = " ";

void setup() {
 size (600,800);
 font = loadFont ("Eureka-24.vlw");
 textFont(font);
 stroke(255);
 fill(0);
}

void draw() {
background(204);
float cursorPosition = textWidth (letters);
line(cursorPosition,0,cursorPosition,100);
text(letters,0,50);
}

void keyPressed() {

 if (key == BACKSPACE) {
 if(letters.length()>0) {
 letters = letters.substring(0,letters.length()-1);
 }
 }else if (textWidth(letters+key) < width) {
    letters = letters+key;
 
} if (key==RETURN){}
}

thanks
