The GtkFileChooserButton widget is an implementation of the functionality provided by the GtkFileChooser interface. This means that, while the button is not derived from GtkFileChooser, it can be treated as a file chooser if you cast it with GTK_FILE_CHOOSER(). You will notice that quite a few of the functions in Listing 4-10 utilize functions provided by GtkFileChooser. In Listing 4-10, gtk_file_chooser_set_current_folder() was used to set the current folder of each file chooser button to the user s home directory. The contents of this folder will be shown when the user initially clicks a file chooser button unless it is changed through some other means. This function will return TRUE if the folder was successfully changed. gboolean gtk_file_chooser_set_current_folder (GtkFileChooser *chooser, const gchar *filename); The g_get_home_dir() function is a utility function provided by GLib that returns the current user s home directory. As with most features in GLib, this function is cross platform. This brings up a useful characteristic of the file chooser interface; it can be used to browse many types of file structures, whether it is on a UNIX or Windows machine. This is especially useful if you want your application to be compiled for multiple operating systems. Since the file chooser button only allows one file to be selected at a time, you can use gtk_file_chooser_get_filename() to retrieve the currently selected file or folder, depending on the type of file chooser button. If no file is selected, this function will return NULL. The returned string should be freed with g_free() when you are finished with it. gchar* gtk_file_chooser_get_filename (GtkFileChooser *chooser); At this point, you have enough information about the GtkFileChooser interface to implement file chooser buttons. GtkFileChooser will be covered in more depth in the next chapter when you learn about the GtkFileChooserDialog widget.

GtkFileFilter objects allow you to restrict the files shown in the file chooser. For example, in Listing 4-10, only PNG, JPG, and GIF files could be viewed and chosen by the user when the Image Files filter was selected. File filters are created with gtk_file_filter_new(). Therefore, you need to use gtk_file_filter_set_name() to set a displayed name for the filter type. If you provide more than one filter, this name will allow the user to switch between them. GtkFileFilter* gtk_file_filter_new (); void gtk_file_filter_set_name (GtkFileFilter *filter, const gchar *name); Lastly, for a filter to be complete you need to add types of files to show. The standard way of doing this is with gtk_file_filter_add_pattern() as shown in the following code snippet. This function allows you to specify a format for the filenames that are to be shown. Usually identifying file extensions that should be shown does this. You can use the asterisk character as a wildcard for any type of filtering function. void gtk_file_filter_add_pattern (GtkFileFilter *filter, const gchar *pattern);

To do this, you should create a filter with only one pattern set to the wildcard character. If you do not provide this filter, the user will never be able to view any files that do not match a pattern provided by another filter.

You can also specify filter patterns with gtk_file_filter_add_mime_type() by specifying the Multipurpose Internet Mail Extensions (MIME) type. For example, image/* will show all files that are an image MIME type. The problem with this function is that you need to be familiar with MIME types. However, the advantage of using MIME types is that you do not need to specify every file extension for a filter. It allows you to generalize to all files in a specific MIME category. void gtk_file_filter_add_mime_type (GtkFileFilter *filter, const char *mime_type); After you create the filter, it needs to be added to the file chooser, which can be done with gtk_file_chooser_add_filter(). Once you supply the filters, the first specified filters will be used by default in the file chooser. The user will be able to switch between types if you have specified multiple filters. void gtk_file_chooser_add_filter (GtkFileChooser *chooser, GtkFileFilter *filter);
