At times, you may want to process all pending events in an application. This is extremely useful when you are running a piece of code that will take a long time to process. This will cause your application to appear frozen, because widgets will not be redrawn if the CPU is taken up by another process. For example, in an integrated development environment that I have created called OpenLDev, I have to update the user interface while a build command is being processed. Otherwise, the window would lock up, and no build output would be shown until the build was complete. The following loop is the solution for this problem. It is the answer to a great number of questions presented by new GTK+ programmers. while (gtk_events_pending ()) gtk_main_iteration (); The loop calls gtk_main_iteration(), which will process the first pending event for your application. This is continued while gtk_events_pending() returns TRUE, which tells you whether there are events waiting to be processed.

19.5 Summary

When setting Location: headers, ensure that the URL supplied is indeed a well-formed http URL. In particular, if it starts with a scheme (xxxx:), the scheme must be http or https. Furthermore, it must consist only of characters that are permitted to occur non-escaped in a URL as specified in the relevant standard, RFC 2396 (Berners-Lee, Fielding, and Masinter 2005). When setting cookies, ensure that the cookies names and values contain only characters allowed by the relevant standard, RFC 2965 (Kristol and Montulli 2000). When setting other headers (e.g., X-Mycustomheader:) ensure that the header values (as well as header names) contain only characters allowed by the HTTP/1.1 protocol specification in RFC 2616 (Fielding et al. 1999).

Using this loop is an easy solution to the freezing problem, but a better solution would be to use coding strategies that avoid the problem altogether. For example, you can use idle functions, which will be covered in 6, to call a function only when there are no actions of greater importance to process.

In this chapter, we applied a simple refactoring to remove business logic from the controller and move it into a useful abstraction. By properly managing our dependencies and adhering to object-oriented principles, we re better equipped to craft welldesigned software with functionality that can be easily verified. We extended ControllerActionInvoker and DefaultControllerFactory to manage action filters. Deriving from ActionResult allowed us to avoid repetitive code

The GtkButton widget is a special type of container that turns its child into a clickable entity. It is only capable of holding one child. However, that child can be a container itself, so the button can theoretically be the ancestor of large amounts of children. This allows the button to hold, for example, a label and an image at the same time. Because the purpose of a GtkButton widget is to make the child clickable, you will almost always need to use the clicked signal to get notification of when the button is activated. You will use this signal in the following example. The GtkButton widget is usually initialized with gtk_button_new_with_label(), which creates a new button with a GtkLabel as its child. If you want to create an empty GtkButton and add your own child at a later time, you can use gtk_button_new(), although this is not what you will want to do in most cases. Figure 2-4 shows a button with mnemonic capabilities. You can recognize a mnemonic label by the underlined character. In the case of the button below, when Alt+C is pressed, the button will be clicked.

while not relying on filter attributes. Finally, we leveraged an application bus to write simple, declarative controller actions. In the next chapter, you ll learn the importance and mechanics of creating fullsystem tests for ASP.NET MVC applications.

Restricting character sets to the characters allowed by the various specifications ensures that the HTTP response will be parsed by the browser correctly and as intended. Validating the URL ensures that only redirects to valid HTTP URLs can occur not to, for instance, a javascript: URL. While modern browsers will not execute script in a redirect to a javascript: URL, older browsers might. As always, we follow the whitelist, not blacklist paradigm.

Figure 2-4. A GtkButton widget with a mneumonic label The function gtk_button_new_with_mnemonic() will initialize a new button with mnemonic label support. When the user presses the Alt key along with the specified accelerator key, the button will be activated. An accelerator is a key or set of keys that can be used to activate a predefined action.
