Vaadin – Using Input Components and Forms

by Alejandro Duarte | August 2013 | Beginner's Guides Open Source

Vaadin is an open source framework to ease development of Java web applications that provides a programming model close to Swing or AWT. Vaadin is licensed under the Apache License, is well documented, comes with out-of-the-box theming facilities, and is supported by a committed company and a vibrant community contributing to the framework through forums and hundreds of add-ons. Vaadin allows developers to write web applications using only Java. Of course, HTML, CSS, and JavaScript are building blocks of web application development, however, by using Vaadin, developers will be maintaining Java code most of the time.

In this article, by Alejandro Duarte, the authors of Vaadin 7 UI Design By Example Beginner's Guide, we will take a closer look at the main components for retrieving and processing all the data that users want your application to be aware of. This article will cover the following topics:

  • Separating business classes from UI classes
  • Responding to value changes in input components
  • Getting and setting the value of input components
  • Tooltips and error indicators
  • Underlying Vaadin technologies
  • UI components hierarchy
  • Vaadin's data model
  • Comboboxes, checkboxes, text areas, option groups, twin column selects, and date/time pickers
  • File uploading

Validating and Using the Model Data

by Vinod Krishnan | May 2013 | Beginner's Guides Enterprise Articles Oracle

In this article by Vinod Krishnan, author of Oracle ADF 11gR2 Development Beginner's Guide, we will take a look at validating and using the model data. Validating data is important as business depends on the data that gets stored in the database. So how do we validate the data? Validation is something that makes sure that valid data is getting stored in the database. Validation could be anything from comparing two fields in a table to multiple validations on a single field involving different columns from a different table.

In any other framework, we would end up writing a lot of code even for a small validation. But in ADF, we do little or no coding at all, and most of the validations are achieved declaratively.

In this article, we will learn the following topics:

  • Declarative validation
  • Groovy expressions

Viewing on Mobile Devices

by Will Hacker | November 2013 | Open Source

In this article by Will Hacker, the author of the Mobile Prototyping with Axure 7, we will learn about getting our work on the mobile devices. The main reason for creating a prototype is to exercise a design idea to see if it matches the expectations of stakeholders and can be easily used by the people for whom we are designing. If it doesn't, and we fail, that's OK. That's why we make prototypes. Failing fast and learning from that are important parts of iterative design.

In this article we'll look at:

  • Publishing prototypes to AxShare
  • Creating home screen icons
  • Creating app splash pages

Views, URLs, and Generic Views in Django 1.0

by Scott Newman | July 2009 | Web Development

Many developers new to Django get tripped up on the vocabulary and purpose of different pieces of the system—models, views, generic views, model managers, and so on. With some functions belonging to models and others to views, it can be confusing to know where to put the logic of your applications.

The view is where most of your application logic will be executed. Before we can work with views, however, we need to look at the URL dispatching system to see how a view is matched up with an incoming request. Once we have seen the URL dispatcher and some working views, we'll take a look at some shortcuts Django offers us to accomplish these actions even more quickly.

You can write entire Django sites without using models, but you'd have a hard time doing that without views or generic views.

In this article by Scott Newman, we will:

  • Create a sample application to work with
  • Learn how the URL dispatcher works and how URLs are matched to views
  • Explore the structure of views
  • Build views to display a list of content and content detail
  • See how to cut down development time with generic views
  • Examine when to use regular views instead of generic views

Visual Basic for Applications (VBA)

by Robert Martin | December 2012 | Enterprise Articles Microsoft

Visual Basic for Applications (VBA) is a programming language built into Microsoft Office applications. As you improve your skills in any application from the Office System, you will eventually realize that although Microsoft Office applications offer a large number of tools, they do not offer everything you need to perform your daily chores. Such chores may include creating a corporate custom-format, a custom function that calculates commission payments, and so on.

Thus, VBA works as a gap-filler; in other words, its main purpose is to ensure that you can do whatever you need to do in your job.

In this article by Robert Martin, author of Excel Programming with VBA Starter,you will get to know a bit about VBA, its basic features, what you can do with it, and how you can put it to work with a view to facilitating your daily work, by automating common tasks.
