<!-- ##### SECTION Title ##### -->
GtkFileSelection
<!-- ##### SECTION Short_Description ##### -->
prompt the user for a file or directory name.
<!-- ##### SECTION Long_Description ##### -->
<para>
#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.
</para>
<para>
File selection dialogs are created with a call to gtk_file_selection_new().
</para>
<para>
The default filename can be set using gtk_file_selection_set_filename() and the selected filename retrieved using gtk_file_selection_get_filename().
</para>
<para>
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*.
</para>
<para>
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().
</para>
<para>
<example>
<title>Getting a filename from the user.</title>
<programlisting>
/* The file selection widget and the string to store the chosen filename */
void store_filename (GtkWidget *widget, gpointer user_data) {
GtkWidget *file_selector = (GtkWidget *)user_data;
const gchar *selected_filename;
selected_filename = gtk_file_selection_get_filename (GTK_FILE_SELECTION (file_selector));
g_print ("Selected filename: %s\n", selected_filename);
}
void create_file_selection (void) {
GtkWidget *file_selector;
/* Create the selector */
file_selector = gtk_file_selection_new ("Please select a file for editing.");
g_signal_connect (GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->ok_button),
"clicked",
G_CALLBACK (store_filename),
(gpointer) file_selector);
/* Ensure that the dialog box is destroyed when the user clicks a button. */
g_signal_connect_swapped (GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->ok_button),
"clicked",
G_CALLBACK (gtk_widget_destroy),
(gpointer) file_selector);
g_signal_connect_swapped (GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->cancel_button),

/* Display that dialog */
gtk_widget_show (file_selector);

<!-- ##### FUNCTION gtk_file_selection_new ##### -->
<para>
Creates a new file selection dialog box. By default it will contain a #GtkTreeView 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.
</para>
@title: a message that will be placed in the file requestor's titlebar.
@Returns: the new file selection.

<para>
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 "Folders"
list those directories which have been partially matched.
</para>
@filesel: a #GtkFileSelection.
@pattern: a string of characters which may or may not match any filenames in the current directory.
<!-- ##### FUNCTION gtk_file_selection_show_fileop_buttons ##### -->
<para>
Shows the file operation buttons, if they have previously been hidden. The rest of the widgets in the dialog will be resized accordingly.
</para>
@filesel: a #GtkFileSelection.
<!-- ##### FUNCTION gtk_file_selection_hide_fileop_buttons ##### -->
<para>
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.
</para>
@filesel: a #GtkFileSelection.
