Autosize TextField to text width

Question

Hi,
I want to have my TextField automatically resize to be the width of the text in it. Currently it seems to be fixed width (when added to a FlowLayout) and the text inside scrolls (pans out to the left) when the max size is reached.
I have worked out a nasty hack that manually tries to set the preferred width:
inputField = new TextField();
inputField.textProperty().addListener(new ChangeListener<String>()
    public void changed(ObservableValue<? extends String> observableValue, String s, String s1)
        int cols = s1 != null ? Math.max(2, s1.length() + 1) : 2;
        inputField.setPrefWidth(cols * 8);
});This is nasty code, but also it doesn't adjust the size to the font used by the TextField (and there is no getFont that I can see?).
Does anyone know if there is either another (nicer) way to do this or, at least a way to determine the width of a string on the TextField?
Note, I have tried setPrefColumnCount but this seems to have no affect after the field has been created. I have also tried the 'autosize' method on TextField but it doesn't seem to do anything in this context either.
Cheers,

After a few hours of search I have finally found myself an answer! What you have to do to get this working is very simple indeed.
I found my answer in the Adobe Designer help files here is the contents I have found:
Floating fields in a dynamic form
You can insert a floating field into a text object to display different types of information.
Floating fields are text field objects that support the merging of text, numeric values, run-time properties, and scripting within a text object when the form is rendered. You can insert floating fields into text objects only.
Because floating fields are text field objects, you can bind floating fields to a data source to display specific text or numeric values. For example, you can insert a floating field (Dear Mr./Ms. {TextField}), to render individual customer names in the introductory greeting of a form letter.
Note: Floating fields are text field objects by default, but you can change the object type using the Type list in the Field tab of the Object palette, to suit your needs.
Keep in mind that you must set the properties of the floating field object independently of setting the properties of the text object. By default, floating field objects are set to Hidden (Exclude from layout) in the Presence list.
To insert a floating text field into a text object:
Click inside the text object in which you want to place the floating text field object.
Place your cursor on the line where you want Designer to insert the floating text field object.
Select Insert > Floating Field.
To set the properties of the floating field, click the floating field marker inside the text object, and then select options as needed. It is good practice to rename the floating text field object and specify the necessary binding.
