GtkFileSelection
prompt the user for a file or directory name.
#GtkFileSelection should be used to retrieve file or directory names from
the user. It will create a new dialog window containing a directory list,
and a file list corresponding to the current working directory. The filesystem
can be navigated using the directory list or the drop-down history menu.
Alternatively, the TAB key can be used to navigate using filename
completion - common in text based editors such as emacs and jed.
File selection dialogs are created with a call to gtk_file_selection_new().
The default filename can be set using gtk_file_selection_set_filename() and the selected filename retrieved using gtk_file_selection_get_filename().
Use gtk_file_selection_complete() to display files and directories
that match a given pattern. This can be used for example, to show only
*.txt files, or only files beginning with gtk*.
Simple file operations; create directory, delete file, and rename file, are available from buttons at the top of the dialog. These can be hidden using gtk_file_selection_hide_fileop_buttons() and shown again using gtk_file_selection_show_fileop_buttons().
Getting a filename from the user.

/* Create the selector */

#GtkDialog
Add your own widgets into the #GtkFileSelection.
The #GtkFileSelection struct contains the following #GtkWidget fields:
*fileop_dialog;
the dialog box used to display the #GtkFileSelection. It can be customized by adding/removing widgets from it using the standard #GtkDialog functions.
*dir_list, *file_list;
the two #GtkCList widgets corresponding to directories and files.
*ok_button, *cancel_button;
the two main buttons that signals should be connected to in order to perform an action when the user hits either OK or Cancel.
*history_pulldown;
the #GtkOptionMenu used to create the drop-down directory history.
*fileop_c_dir, *fileop_del_file, *fileop_ren_file;
the buttons that appear at the top of the file selection dialog. These "operation buttons" can be hidden and redisplayed with gtk_file_selection_hide_fileop_buttons() and gtk_file_selection_show_fileop_buttons() respectively.
Creates a new file selection dialog box. By default it will contain a #GtkCList of the application's current working directory, and a file listing. Operation buttons that allow the user to create a directory, delete files and rename files, are also present.
@title: a message that will be placed in the file requestor's titlebar.
@Returns: the new file selection.
@filesel:
@filename:
@filesel:
@Returns:
Will attempt to match @pattern to a valid filenames or subdirectories in the current directory. If a match can be made, the matched filename will appear in the text entry field of the file selection dialog.
If a partial match can be made, the "Files" list will contain those
file names which have been partially matched, and the "Directories"
list those directories which have been partially matched.
@filesel: a #GtkFileSelection.
@pattern: a string of characters which may or may not match any filenames in the current directory.
Shows the file operation buttons, if they have previously been hidden. The rest of the widgets in the dialog will be resized accordingly.
@filesel: a #GtkFileSelection.
Hides the file operation buttons that normally appear at the top of the dialog. Useful if you wish to create a custom file selector, based on #GtkFileSelection.
@filesel: a #GtkFileSelection.
