The floor() function is used to convert the cursor position into a number between zero and three, which represents what IP address value should be edited. The event string is also converted into an integer with g_ascii_digit_value(). Now that you have all of the necessary values, two conditionals check the validity of the new value. The new integer will only be appended to the current value if the new value will not exceed 255. If the number is within bounds, the current value is scaled, and the new integer is appended. Next, the new IP address is rendered in the GtkEntry widget, and the cursor position refreshed. Lastly, g_signal_emit_by_name() is used to inform the user that the IP address was changed. The second conditional handles the Tab key, which will cycle through each of the four numbers when pressed. This could be altered in another implementation of the widget to cycle to the next widget in the tab order when the end of the widget is reached. Next, the Backspace key divides the current value by ten. Since you are dividing an integer by an integer, the remainder is ignored, and the last digit is dropped off. Then, the widget is rendered, and the ip-changed signal emitted. Lastly, the Return and Enter keys call gtk_widget_activate() when pressed. This allows the user to press these keys to activate the default widget of the window from within the MyIPAddress widget. All other key presses besides those covered in this section are ignored.

The last step to create the widget is to implement the public functions declared in the widget s header file. The first function is my_ip_address_new(), which creates a new MyIPAddress widget in Listing 11-13. Listing 11-13. Creating a New MyIPAddress Widget GtkWidget* my_ip_address_new () { return GTK_WIDGET (g_object_new (my_ip_address_get_type (), NULL)); } You should notice that the only task this function provides is casting to a GtkWidget the object returned by g_object_new(). This is simply a convenience function for many widgets, so the programmer does not need to create the GObject instance itself. If you are using widgets that accept parameters into their initialization functions, you would handle those here. The my_ip_address_get_address() function in Listing 11-14 returns a string representation of the IP address that is currently stored by the widget. This returned string must be freed when the programmer is finished with it, since it is created with g_strdup_printf(). While the user can construct this programmatically, most widgets usually provide a number of convenient functions that perform tasks that will be needed often.

Object-oriented programming doesn t directly relate to TDD, because object-oriented development is possible with a single class What s different is that instead of designing an overall object-oriented architecture ahead of time, the types evolve with the application s implementation The ramification of this is that you don t know what all the types are ahead of time This ramification doesn t fall within the parameters of traditional object-oriented development A new development strategy has been created called test-driven development (TDD) It says for each piece of functionality introduced, a test is written before the code is written Many developers consider test scripts as being created and executed by another department or individual The result is an inconvenient timeline Consider it as follows: you have five months to complete an application In the original timeline, three months are planned for development, and two months for testing.

// Iterate using indexing. for (int i = 0; i < array_list->Count; i++) { Console::WriteLine("{0} {1}", i, array_list[i]); } } Often, code that uses the generic collections, such as ArrayList, will use a cast when objects are retrieved from the collection. If the cast fails, InvalidCastException is thrown, and Listing 11-20 traps this. Listing 11-20. Trapping an InvalidCastException // casting_from_object.cpp using namespace System; using namespace System::Collections; ref class Book { public: Book() { } Book(String^ _title) { Title = _title; } property String^ Title; }; int main() { ArrayList^ theList = gcnew ArrayList(); theList->Add( gcnew Book("Of Mice and Men") ); // Use a cast to retrieve an object from the list // and convert to the appropriate type.
