Text Fields

leclerke

On the internet I found the following sketch which works perfectly on processing 2.2.1 but not on 3.1.1. Why is that and how can I make it run?

import java.awt.*;

Label textFieldLabel = new Label("Titel des Fensters: ");
TextField textField = new TextField("Ein Fenster", 16);

void setup(){
  size(800, 600);
  add(textFieldLabel);
  add(textField);
}

void draw(){
  frame.setTitle(textField.getText());
}

Repet

What error does it display when run in 3.1.1?

"The function "add(Label)" does not exist" & "The function "add(TextField)" does not exist"

v2 PApplet extended Applet and those methods are methods on Applet

http://grepcode.com/file/repo1.maven.org/maven2/org.processing/core/2.2.1/processing/core/PApplet.java (warning, slow)

v3 PApple doesn't extend Applet so you lose those methods (which are java awt components)

but there may be new / other ways of changing the window title (if that's what you're doing)

Actually I was looking for an easy way to create text inputs fields. I don't like the G4P GUI...

there are 3 other libraries in the 'gui' section here. but i have no direct experience of any of them.
