The unsung heroes of every application are the simple things like buttons, menus, and toolbars. In this article by Shea Frederick, Steve 'Cutter' Blades, and Colin Ramsay, we will cover how to add these items to our applications.
Our example will contain a few different types of buttons, both with and without menus. A button can simply be an icon, or text, or both. Toolbars also have some mechanical elements such as spacers and dividers that can help to organize the buttons on your toolbars items.
We will also cover how to make these elements react to user interaction.Read Buttons, Menus, and Toolbars in Ext JS in full
From the very beginning, it was clear that Sakai needed to exist in universities at enormous scales, supporting hundreds of thousands of students. With requirements changing and evolving, and ever-increasing user expectations, Sakai had to be able to connect with a multitude of external systems. When Sakai was designed, the specifics of the majority of the connected systems were not knowable. To adapt to these tough circumstances, Sakai supplies web services that are easy to hook into or to write. Sakai exposes services for creating and maintaining users, sites, and groups. These services are easily extensible to include any part of the Sakai framework.
In this two-part article by Alan Mark Berg and Michael Korcuska, we will look at the two main types of web service, SOAP (Simple Object Access Protocol) and Representational State Transfer (REST) (http://microformats.org/wiki/rest). We will cover already-existing web services and describe how to hook into them. If you follow the examples, you will be able to write and deploy your first service. Lastly, this article includes a few simple client-side Perl scripts that create new users using both the SOAP and RESTful approaches.Read Sakai Web Services: Connecting to the Enterprise (Part 1) in full
