Many of these correspond directly to events in the X Window System and are appropriately named by suffixing them with "-event" These are typically useful only when extending GTK+ beyond its default behaviors and abilities, which will be discussed in the next chapter You will generally rely more on higher-level signals emitted by widgets To connect a callback function to a signal, call g_signal_connect(): g_signal_connect (GObject *instance, const char *signal_name, GCallback *callback, void *data); The instance argument represents the object you re connecting to You must attach to each instance of the object individually; you obviously don t want the same behavior for every button You may, however, connect the same callback to more than one instance The "clicked" signal of each Send button in a Gaim conversation is connected to the same function, but to a different button from the Get Info button.

Similarly, you can use the ModelForm helper you saw in 9 as a way to quickly and easily generate a form for adding or editing any type of object. Because ModelForm works the same way for any model (although customizations such as the exclude feature are typically filled in on a per-model basis), you can use it with any of multiple models, even if you don t know in advance what model you ll be working with.

The signal_name argument is the string identifier for this signal that is listed in the API documentation The callback argument is the function to be called when the signal is emitted The data argument is a pointer passed to that callback function When you connect more than one instance of a button (or other widget) to the same function, the data argument determines what instance triggered the callback When Gaim connects to the "clicked" signal of a Send button, it uses a pointer to the conversation as its data That way, the callback knows which conversation it should send from..

Figure 4-3 shows the output of the sar -u command, displaying CPU utilization with five samples in 10-second intervals.

The callback is a function pointer, the arguments and return type of which will depend on the signal. The arguments will provide any relevant information about the signal that was emitted. Callbacks rarely require a return value, but when they do (as in the low-level X Window System

In addition to writing views that take optional arguments to customize their behavior, you can also build flexibility into your nonview code by not tying it to specific models or specific ideas of how it ought to work. To see what I mean, think back to the weblog application: when you added the comment-moderation feature, you made some assumptions that limited its flexibility. The solution in that case was to instead use Django s built-in moderation system, which was designed to be truly generic. And although Django s moderation system is a bit more complex than the commentmoderation feature you originally wrote for the weblog, it pays off in incredible flexibility. You can set up a different set of moderation rules for each model you allow comments on, and when you need to support custom moderation rules that aren t covered by the code in the CommentModerator class, you can subclass it, write the appropriate code for your custom moderation rules, and then use that subclass to handle your comment moderation. This is a type of situation that recurs frequently in Django application development: a feature that starts out tied to a particular application, or even to a particular model, turns out to be useful in other contexts and gets rewritten to be generic. In fact, that s precisely how Django s
