Create editable lable/text?

Question

I want to add text to a rectangle drawn.

canvas.fillRect(...)

But I would like the user to enter custom text for this rectangle. But how can I create an editable label in gwt canvas that can take user input?

I want to achieve this in gwt canvas JAVA! Not JS.

The drawstring method here might be of some use :)

Sorry I forgot to mention that I do not want to use JS here. Just from GWT Java. – membersound Dec 04 '12 at 22:11
No problem :) There is a fillText() method that you can use. I don't like just handing out code to people, so try googling for it. :) – christopher Dec 04 '12 at 22:13
ok thanks, I see I can call `context.fillText("text");` but still I have no idea how to make this drawn text editable to the user... – membersound Dec 04 '12 at 22:16
Well then you'll need some form of user input control. That'll be the first thing :) – christopher Dec 04 '12 at 22:30

1) Create a JTextField with the same location as your Graphics.fillRect().

JTextField txtSomething = new JTextField(...)

2) Make the JTextField background transparent.

txtSomething.setBackground(new Color(0,0,0,0))

3) Run

There are other ways of doing this, try to research

This won't help for a GWT project, which is Java compiled to JavaScript. – Colin Alworth Dec 05 '12 at 03:04
So for web dev I assume I have to create a transparent inputfield overlay which is then rendered into a label (and back for editing)? – membersound Dec 05 '12 at 07:14
