New GtkLayout widgets are created with gtk_layout_new(), which accepts horizontal and vertical adjustments. Adjustments will be created for you if you pass NULL to both function parameters. Since GtkLayout has native scrolling support, it can be much more useful than GtkDrawingArea when you need to use it with a scrolled window. GtkWidget* gtk_layout_new (GtkAdjustment *hadjustment, GtkAdjustment *vadjustment); However, GtkLayout does add some overhead, since it is capable of containing widgets as well. Because of this, GtkDrawingArea is a better choice if you only need to draw on the widget s GdkWindow. Child widgets are added to a GtkLayout container with gtk_layout_put(), which will place the child with respect to the top-left corner of the container. Since GtkLayout is derived directly from GtkContainer, it is able to support multiple children. void gtk_layout_put (GtkLayout *layout, GtkWidget *child_widget, gint x, gint y); A call to gtk_layout_move() can be used at a later time to relocate the child widget to another location in the GtkLayout container.

Designing domain models Exploring a real-world domain model Understanding entities and value objects Thinking about persistence

Caution Because you place child widgets at specific horizontal and vertical locations, GtkLayout presents the same problems as GtkFixed. You need to be careful of these when using the layout widget! You can read more about the problems with the GtkFixed widget in 3.

In addition to the considerations in the previous section, we have to keep in mind an additional complication that arises with JavaScript in the context of a JavaScript-valued tag attribute such as an onLoad or onClick handler: the values of such attributes are HTMLunescaped before they are passed to the JavaScript interpreter.

In chapter 2 we explored the M in MVC the presentation model our controllers beam through a prism of markup, refracted onto the screen by the view. For the most part, the presentation model doesn t contain any behavior. Its power is in its shape and structure, not in its algorithms and interactions. The presentation model serves the user interface. Deeper, toward the application s core, there s another focus: the logic and code that do the work. The core also contains the valuable calculations and business rules that make the application worth using. In an ecommerce application, this focus might be on orders and products, and in a hotel management system the focus might be on reservations and rooms. This other focus we ll call it the application s domain deserves a model too: the domain model. In this chapter, we ll explore a sample model for a simple system that manages a small ecommerce business. The model enables the application to provide an

Lastly, if you want to force the layout to be a specific size, you can send new width and height parameters to gtk_layout_set_size(). You should use this function instead of gtk_widget_set_size_request(), because it will adjust the adjustment parameters as well. void gtk_layout_set_size (GtkLayout *layout, guint width, guint height); Also, unlike size requests, the layout sizing function requires unsigned numbers. This means that you must specify an absolute size for the layout widget. This size should be the total size of the layout, including portions of the widget that will not be visible on the screen because they are beyond the bounds of the scrolling area! The size of a GtkLayout widget defaults to 100 pixels by 100 pixels.

interesting service. Without the model, the application provides no value. We place great importance on creating a rich model that clearly expresses the business reality and the solution to problems in that domain. The style of modeling we ll use in this book is domain-driven design (DDD), as conveyed by Eric Evans in his book, Domain-Driven Design: Tackling Complexity in the Heart of Software. Covering the topic in depth takes a book in itself; we ll tackle a small primer, which should enable you to follow the software examples in the rest of this book. After the DDD primer, we ll discuss how to best use the domain model, and then we ll look at how to use a presentation model to keep controllers and views simple. We ll keep a keen eye on separation of concerns to ensure that every class has a single, well-defined responsibility.

GTK+ provides the GtkCalendar widget, which is a widget that displays one month of a calendar. It allows the user to move among months and years with scroll arrows, as shown in Figure 12-2.
