JavaFX 2.x custom component compatible with FXML

In November, last year, I wrote a little example on how to extend an existing component in JavaFx 2.0.
Today, I would use this component in FXML and make a little demo.
The application for the demo is very simple:

• One SearchTextBox component (custom component) with events on OnCrossButtonMouseClicked and OnSearchEvent.
• One ComboBox to change the font size of the SearchTextBox component.
