I am completely new to JavaFX, well any UI development in Java if I am honest. I am using fxml to define my screen layout.
I want an application that uses tabs, witht he first tab having an internal layout rather similar to the IssueTracker sample application. I have created the below fxml file which looks about right, however when I resize the application the tabs and their contents do not resize with the screen.
How do I make this resize? Do I need to do it within code or can I do it within the fxml?
Thanks

Javafx components automatically adjust themselves according to the size available to them. Try removing the prefHeight and prefWidth, as it forces the components to use a particular dimension.
The blank space at the bottom of the screen could be because of placing everything under VBox. If i understand it right, you need to have a menubar on the top and Tabpane at the center of the screen. If thats the case, instead of VBox, try using Borderpane with Menubar added to Top and TabPane added to the center of BorderPane.
