I'm trying to layout a Stage using a GridPane as the root of the Scene.

```
row 1 contains a HBox
row 2 contains a SplitPane with orientation set to Vertical

```

The SplitPane contains a browser control and another SplitPane with orientation set to Horizontal. The inner SplitPane contains two TableViews. 

I'm try to have the outer SplitPane resize as the window changes size (please forgive if I'm not using the correct terms). I've seen how this can be done when using fxml but I'm restricted to using Javafx 8 and must do this programmatically. If it matters I'm using Netbeans 8.1.

It would be most appreciated if someone could point me in the right direction.

thank you
A.G.
