JavaFX 2 define onChange listener in FXML

Question

I am busy teaching myself FXML. I'm doing this by following this example.

It's a simple text editor. However, in the tutorial everything is Java code.

I myself am using FXML to seperate the view of the logic.

I currently face the following challenge:

I have defined an TextArea in my FXML like so:

<TextArea id="taTextArea" fx:id="taContent" wrapText="true" />

Usually you add action listeners using onAction="#actionName"

What I want to know is, how can I do something similar for text changes. So I can detect wether a save is needed, modify the status bar label etc.

I want to avoid having to attach the TextArea to a change listener in the init method of the controller(implementing Initializable).

Also.. when I complete this application, I will write a blog about it. With the lacking FXML documentation, I think itll be helpfull to other newbies. So I want my code to be as clean as possible.

EDIT 1

No progress yet. I need to know if theres a thing such as code completion in FXML So I can check what kind of properties I can use in FXMl. There should be a textLength property. In the provided link the author uses lengthProperty.addListener. I need an FXML equivilant

Answer 1

You could use the onKeyPressed property:

onKeyPressed="#textChanged"

which calls the textChanged method in the specified controller.

For the second question: The best reference for FXML currently is the javadoc of JavaFX, since all properties are listed there.
