Layout

[Randahl Fink Isaksen]

Tom, the problem is, extending Pane directly is a lot of work. Pane does not implement a layout strategy and therefore does not implement computePrefWidth and computePrefHeight; consequently if you just nest a lot of Panes inside one another, none knows anything about size.

So, instead of extending Pane directly I have found it much more useful to extend one of the subclasses which has a layout strategy such as BorderPane, GridPane, etc. And up until this point I have not yet seen a layout that could not be implemented as an (arguably bloated) tree of subclasses of Pane.

Once you extend, say, BorderPane, invoking setPrefSize(double, double) *does* have an effect.

Yours

In short: Either invoke setSize and ensure
