There are some great benefits to implementing controller actions like a storyboard. Actions tend to become smaller and focused, with business logic moving out of the action and into supporting services. As a result, the actions are less complex and easier to test. A lean action should result in two possible outcomes: happy path (a successfully processed request) or an alternate path. If an action starts branching to handle multiple alternate paths, this is a sign that the action method is handling too much, and some effort should be put into designing the storyboard of the application. Figure 4.1 shows a sample storyboard illustrating how a user would log into a web application and then view some customized content. The action that handles the many of these widgets as you want in one file. The only requirement is that the whole file content is contained between the <ui> and </ui> tags. free download qr code scanner for java mobile gwuhaolin/pure-svg-code: Generate qrcode & barcode to ... - GitHub

Although this seems like an obvious path that needs to be developed, it s easy to overlook the alternate paths when you don t storyboard them. This technique helps developers and designers communicate how the screens should work before a single line of code is written. In addition to toolbars and menu bars, it is possible to define pop-up menus in a UI file, as illustrated in Listing 9-10. Notice that there are repeated actions in Listings 9-8, 9-9, and 9-10. Repeating actions allows you to define only a single GtkAction object instead of separate objects for each instance of an "action". Listing 9-10. Pop-up UI File (popup.ui) <ui> <popup name="EntryPopup"> <menuitem name="EditCut" action="Cut"/> <menuitem name="EditCopy" action="Copy"/> <menuitem name="EditPaste" action="Paste"/> <separator/> <menuitem name="EditSelectAll" action="SelectAll"/> <menuitem name="EditDeselect" action="Deselect"/> </popup> </ui> The last type of top-level widget supported by UI files is the pop-up menu, denoted by the <popup> tag.
