In the exercise for this chapter, you will be creating custom dialogs of your own. Each of the dialogs will be implementations of different types of file chooser dialogs. However, you will be embedding a GtkFileChooserWidget into a GtkDialog to recreate the functionality of the builtin dialogs.

In this exercise, create a window with four buttons. Each button will open a different dialog when clicked that implements one of the four GtkFileChooser actions. You should use GtkFileChooserWidget added to a GtkDialog instead of the prebuilt GtkFileChooserDialog. 1. Your dialog will implement a GTK_FILE_CHOOSER_ACTION_SAVE file chooser dialog. The chosen file name should be printed to the screen. 2. Your dialog will implement a GTK_FILE_CHOOSER_ACTION_CREATE_FOLDER file chooser dialog. The new folder name should be printed to the screen. You will have to manually create the new folder with g_mkdir(). 3. Your dialog will implement a GTK_FILE_CHOOSER_ACTION_OPEN file chooser dialog. The chosen file names should be printed to the screen. 4. Your dialog will implement a GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER file chooser dialog. The chosen folder path should be printed to the screen. For each of the dialogs, you need to make sure to set it to a decent size so that the whole content can be visible to the user. If you get stuck on this exercise, you can find one possible solution in Appendix F.

In this chapter, you learned how to create your own custom dialogs. To do this, you need to first initialize the dialog. Then, action area buttons need to be added as well as the main content to the dialog s GtkVBox. Dialogs can be created as modal or nonmodal. A modal dialog created with gtk_dialog_ run() blocks the user from interacting with the parent window until it is destroyed by creating a main loop for the dialog. It also centers the dialog above its parent window. Nonmodal dialogs allow the user to interact with any other window in the application and will not force focus on the dialog.

After learning about the built-in dialogs, you learned about multiple types of built-in dialogs provided by GTK+: Message dialog (GtkMessageDialog): Provide a general message, error message, warning, or simple yes-no question to the user. About dialog (GtkAboutDialog): Show information about the application including version, copyright, license, authors, and others. File chooser dialog (GtkFileChooserDialog): Allow the user to choose a file, choose multiple files, save a file, choose a directory, or create a directory. Color selection dialog (GtkColorSelectionDialog): Allow the user to choose a color along with an optional opacity value. Font selection dialog (GtkFontSelectionDialog): Allow the user to choose a font and its size and style properties. The last section of this chapter showed you a widget called GtkAssistant, which was introduced in GTK+ 2.10. It allows you to create dialogs with multiple stages. It is important to note that assistants are not actually a type of GtkDialog widget but are directly derived from the GtkWindow class. This means that you have to handle these by connecting signals in the main loop instead of calling gtk_dialog_run(). You now have a firm understanding of many important aspects of GTK+. Before we continue on to more advanced widgets, the next chapter will give you a thorough understanding of GLib. 6 will cover many GLib data types, idle functions, timeouts, process spawning, threads, dynamic modules, file utilities, and timers, as well as other important topics.

ow that you have a reasonable grasp of GTK+ and a number of simple widgets, it is time to move to another library. GTK+ depends on GLib, a general-purpose library that provides many kinds of utility functions, data types, and wrapper functions. In fact, you have already used some aspects of GLib in previous chapters. GLib can be run independently of any other library, which means that some of the examples in this chapter do not require the GTK+, GDK, and Pango libraries. However, GTK+ does depend on GLib. Not all of the topics throughout this chapter will be used in later chapters, but all are useful in many GTK+ applications in the real world. Many of the topics are used for very specific tasks. For example, GModule can be used to create a plug-in system for your application or open a binary s symbol table. The goal of 6 is not to be a comprehensive guide to everything in GLib. When using a feature shown in this chapter, you should reference the GLib API documentation for more information. However, this chapter will introduce you to a wide array of important features so that you have a general understanding of what GLib provides. In this chapter, you will learn the following: The basic data types, macros, and utility functions provided by GLib How to give textual feedback to the user about errors and warnings that occur within your application Memory management schemes provided by GLib such as memory slices, g_malloc(), and friends Various utility functions provided by GLib for timing, file manipulation, reading directory contents, and working with the file system How the main loop is implemented in GLib and how it implements timeout and idle functions Data structures provided by GLib including strings, linked lists, binary trees, arrays, hash tables, quarks, keyed data lists, and n-ary trees How to us GIOChannel to manipulate files and create pipes as well as how to spawn asynchronous and synchronous processes How to dynamically load shared libraries with GModule
