PrimeFaces Cookbook

Overview of this book

PrimeFaces is the de facto standard in the Java web development. PrimeFaces is a lightweight library with one jar, zero-configuration, and no required dependencies. You just need to download PrimeFaces, add the primefaces-{version}.jar to your classpath and import the namespace to get started. This cookbook provides a head start by covering all the knowledge needed for working with PrimeFaces components in the real world. "PrimeFaces Cookbook" covers over 100 effective recipes for PrimeFaces 3.x which is a leading component suite to boost JSF applications. The book's range is wide‚Äí from AJAX basics, theming, and input components to advanced usage of datatable, menus, drag & drop, and charts. It also includes creating custom components and PrimeFaces Extensions.You will start with the basic concepts such as installing PrimeFaces, configuring it, and writing a first simple page. You will learn PrimeFaces' theming concept and common inputs and selects components. After that more advanced components and use cases will be discussed. The topics covered are grouping content with panels, data iteration components, endless menu variations, working with files and images, using drag & drop, creating charts, and maps. The last chapters describe solutions for frequent, advanced scenarios and give answers on how to write custom components based on PrimeFaces and also show the community-driven open source project PrimeFaces Extension in action.

Snapping to the edges of the nearest elements

With PrimeFaces, we can snap the dragged component to the inner or outer boundaries of another component (component's DOM element).

In this recipe, we will discuss snapping and its options in detail. As an example, we will develop a big h:panelGroup component as a snap target and three other small h:panelGroup components as draggable components with various snapping options.

How to do it...

Generally, the snapping behavior is activated by setting the attribute snap to true. The snapping behavior is configurable with two options—snapMode and snapTolerance. The first option, snapMode, determines which edges of snap elements the draggable component will snap to. The second option, snapTolerance, determines a distance in pixels the draggable component must be from the element when snapping is invoked.

<h:panelGroup id="snaptarget" layout="block" 
    styleClass="ui-widget-content"
              style="height:150px;width:450px;">
    <p class...
