Resizing Components Within Containers
The Resizable mixin provides a number of functions to identify a given resizable node's sizing preferences, including minimum, preferred, and maximum sizes, as well as fill and grow preferences. The
containerclasses will use these preferences when resizing nodes during layout, however such preferences can be overridden on a per-node basis using theLayoutInfoclass. -
Improving the Dynamic Layout of Your Application
The layout containers automatically manage the dynamic layout behavior of their content nodes. However, it is often desirable to also use the binding mechanism of the JavaFX Script to establish certain dynamic aspects of layout. For example, you can bind the width and height of an HBox container to the
Sceneheight and width so that wheneverSceneresizes, theHBoxcontainer resizes as well.

Don't believe anyone who tells you that you don't need layout management for rich internet applications. While it's true that this emerging class of interfaces are more graphical, fluid, organic, and animating than the traditional rectangular GUIs of the last 20 years, they, by their nature of being "applications" and not merely glitzy ads, must deal with dynamic content and user interaction.
Perhaps some of the bad rap on layout management is due to our own coddling of AWT "Layout Managers", a mostly programmatic approach for achieving layout in Java clients. Anyone who's ever had to design and construct a significant user interface knows that the more natural process is to draw the thing, or at least lay it out visually. But even with the most exceptional tools, the initial layout is just the beginning. The sticky wicket is how to then integrate the dynamic layout behavior -- what should happen if the container is resized or the content changes. Tools like Interface Builder, Dreamweaver, and NetBeans/Mattisse have strived to support this with varying success. The fact is that it's a really hard problem and the graphic sophistication of RIAs only increases the complexity. Dynamic layout now has to also work with timeline based animation and visual effects never anticipated in the aforementioned tool set.
