Letting a TextField loose Focus again
Jul 14^th, 2009, 3:50pm

Hi everyone!
I'm currently writing a program that creates objects upon keyboard input. The user should be able to change the apperance of these objects by typing into one or more TextFields and change variables like labels, size, colour etc...

I've created a TextField by:
Code:

TextField inputLine = new TextField("Blahblah", 15);
add(inputLine);

in the setup().

Initially, the Object creation works fine.
But once you write into the TextField the TextField will obviously get the focus and "keyPressed()" will not be called anymore.

So I'm wondering what I have to do, to return the focus to the initial status, after something has been written into the TextField.

I've tried calling
Code:

  inputLine.setFocusable(false);
  inputLine.setFocusable(true);

right after each other... Roll Eyes

But while the TextField looses it's focus, it doesn't seem like the Programm regains it, because "keyPressed()" still doesn't work.

And by the way, is there an easy way to arrange the TextFields on the screen (and change their apperance)?
I wouldn't exactly be thrilled if I had to write my own TextField class for that... Undecided

Anyways, thanks in advance!

Ah, so that's the AWT TextField!
I haven't guessed it because the FAQ says: "The main rule when using Java code: You cannot use most of the AWT or Swing (which is built on the AWT), because it will interfere with the graphics model. [...] Even if they appear to work, such sketches will usually break when you try to run on other operating systems or other versions of Java."
So I stay away from AWT.

If you still go this way (eg. if that's for your own use), you can try this.requestFocus() perhaps.
