Prompt the user for a file or directory name
<gtk-file-selection> 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.
/* The file selection widget and the string to store the chosen filename */
void store_filename (GtkWidget *widget, gpointer user_data) {
GtkWidget *file_selector = GTK_WIDGET (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_FILE_SELECTION (file_selector)->ok_button,
"clicked",
G_CALLBACK (store_filename),
file_selector);
/* Ensure that the dialog box is destroyed when the user clicks a button. */
g_signal_connect_swapped (GTK_FILE_SELECTION (file_selector)->ok_button,
"clicked",
G_CALLBACK (gtk_widget_destroy),
file_selector);
g_signal_connect_swapped (GTK_FILE_SELECTION (file_selector)->cancel_button,
"clicked",
G_CALLBACK (gtk_widget_destroy),
file_selector);
/* Display that dialog */
gtk_widget_show (file_selector);
}
Derives from
<gtk-dialog>.This class defines the following slots:
show-fileops- Whether buttons for creating/manipulating files should be displayed
filename- The currently selected filename
select-multiple- Whether to allow multiple files to be selected
mchars) ⇒ (ret <gtk-widget>)Creates a new file selection dialog box. By default it will contain a
<gtk-tree-view>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.
- ret
- the new file selection.
<gtk-file-selection>) (filename mchars)Sets a default path for the file requestor. If filename includes a directory path, then the requestor will open with that path as its current working directory.
This has the consequence that in order to open the requestor with a working directory and an empty filename, filename must have a trailing directory separator.
The encoding of filename is preferred GLib file name encoding, which may not be UTF-8. See
g-filename-from-utf8.
- filesel
- a
<gtk-file-selection>.- filename
- a string to set as the default file name.
<gtk-file-selection>) ⇒ (ret mchars)This function returns the selected filename in the GLib file name encoding. To convert to UTF-8, call
g-filename-to-utf8. The returned string points to a statically allocated buffer and should be copied if you plan to keep it around.If no file is selected then the selected directory path is returned.
- filesel
- a
<gtk-file-selection>- ret
- currently-selected filename in the on-disk encoding.
<gtk-file-selection>) (pattern mchars)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.
- filesel
- a
<gtk-file-selection>.- pattern
- a string of characters which may or may not match any filenames in the current directory.
