Layout (original) (raw)

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.

In short: Either invoke setSize and ensure On Oct 4, 2012, at 14:51 , Tom Eugelink <tbee at tbee.org> wrote:

I've posted a thread on the JavaFX forums with problems I run into when writing a Google Calendar style control. I could use advice on how to best do this nested Panes layout. https://forums.oracle.com/forums/thread.jspa?threadID=2447739&stqc=true Tom
