Description

The GtkFileChooserButton is a widget that lets the user select a file. It implements the GtkFileChooser interface. Visually, it is a file name with a button to bring up a GtkFileChooserDialog. The user can then use that dialog to change the file associated with that button. This widget does not support setting the "select-multiple" property to TRUE.

Example 40. Create a button to let the user select a file in /etc

{
  GtkWidget *button;
  button = gtk_file_chooser_button_new (_("Select a file"),
                                        GTK_FILE_CHOOSER_ACTION_OPEN);
  gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button),
                                       "/etc");
}

The GtkFileChooserButton supports the GtkFileChooserActions GTK_FILE_CHOOSER_ACTION_OPEN and GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.

Important

The GtkFileChooserButton will ellipsize the label, and thus will thus request little horizontal space. To give the button more space, you should call gtk_widget_size_request(), gtk_file_chooser_button_set_width_chars(), or pack the button in such a way that other interface elements give space to the widget.
