Question

Hello guys I am building a chat server where I use a textfield on the screen to type in the chat message that the user writes, the idea is that it works like a bubble over a persons head when he types a message.

my question is in order to not make a textbox that is too large or too small is there a way to make the textbox resize (trim if you will) so it adjust to the text written in the textfield?

P.S. I’m using JavaFx scenebuilder to do all of this.

Answer 1

It is time to do some coding behind the scenes(builder) :).
The following code chunk is not a neat solution but better than none. 🙂

// define width limits
textField.setMinWidth(50);
textField.setPrefWidth(50);
textField.setMaxWidth(400);
// add listner
textField.textProperty().addListener(new ChangeListener<String>() {
    @Override
    public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
        textField.setPrefWidth(textField.getText().length() * 7); // why 7? Totally trial number.
    }
});
