Self-made TextField

Hi everyone,

I've started to build an own simple TextField - unfortunately I stuck now :/

Who can take a look at the code, how should I go ahead? Thx indeed!

Boolean TextfieldClick;
void draw() {
//TextField
rect(25, 645, 200, 40);
noStroke();
//Click on the rect.
if(mouseX>25 && mouseX<225 && mouseY>645 && mouseY<685) {
if(mousePressed && mouseButton == LEFT) {
TextfieldClick = true;
}
}
if(TextfieldClick) {
??? (Maybe the keyCode for the Keyboard?)
}
}

boolean TextfieldClick;
void setup() {
size (300, 800);
background(153);
fill(255);
}
void draw() {
background(153);
//TextField
// noStroke();
rect(25, 645, 200, 40);
//Click on the rect.
if (mouseX>25 && mouseX<225 && mouseY>645 && mouseY<685) {
if (mousePressed && mouseButton == LEFT) {
TextfieldClick = true;
}
}
if (TextfieldClick) {
// ??? (Maybe the keyCode for the Keyboard?)
fill(255, 2, 2, 11);
}
else
fill(255);
}
void keyPressed () {
}

tip nr 13 describes how to make text input.

               String myText = 
               "Type something"
               ;
              
               void 
               setup() {
              
               size(
               500
               , 
               500
               );
              
               textAlign(CENTER, CENTER);
              
               textSize(
               30
               );
              
               fill(
               0
               );
              
               }
              
               void 
               draw() {
              
               background(
               255
               );
              
               text(myText, 
               0
               , 
               0
               , width, height);
              
               }
              
               void 
               keyPressed() {
              
               if 
               (keyCode == BACKSPACE) {
              
               if 
               (myText.length() > 
               0
               ) {
              
               myText = myText.substring(
               0
               , myText.length()-
               1
               );
              
               }
              
               } 
               else 
               if 
               (keyCode == DELETE) {
              
               myText = 
               ""
               ;
              
               } 
               else 
               if 
               (keyCode != SHIFT && keyCode != CONTROL && keyCode != ALT) {
              
               myText = myText + key;
              
               }
              
               }

thx janjacobsv... I used following solution:

import java.awt.*;
TextField textField = new TextField("Text", 16);
void setup() {
add(textField);
}
void draw () {
textField.setLocation(25, 655);
}
