+ * Setting up a file chooser dialog + * There are various cases in which you may need to use a #GtkFileChooserDialog: + * To select a file for opening, as for a + * File/Open command. Use + * #GTK_FILE_CHOOSER_ACTION_OPEN. + * + * To save a file for the first time, as for a + * File/Save command. Use + * #GTK_FILE_CHOOSER_ACTION_SAVE, and suggest a name such as + * "Untitled" with gtk_file_chooser_set_current_name(). + * + * To save a file under a different name, as for a + * File/Save As command. Use + * #GTK_FILE_CHOOSER_ACTION_SAVE, and set the existing filename + * with gtk_file_chooser_set_filename(). + * + * To choose a folder instead of a file. Use + * #GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER. + * + * + * + * Old versions of the file chooser's documentation suggested + * using gtk_file_chooser_set_current_folder() in various + * situations, with the intention of letting the application + * suggest a reasonable default folder. This is no longer + * considered to be a good policy, as now the file chooser is + * able to make good suggestions on its own. In general, you + * should only cause the file chooser to show a specific folder + * when it is appropriate to use gtk_file_chooser_set_filename(), + * i.e. when you are doing a File/Save + * As command and you already + * have a file saved somewhere. + * + * + *
+ *
+ * Response Codes + * #GtkFileChooserDialog inherits from #GtkDialog, so buttons that + * go in its action area have response codes such as + * #GTK_RESPONSE_ACCEPT and #GTK_RESPONSE_CANCEL. For example, you + * could call gtk_file_chooser_dialog_new() as follows: + * + * + * GtkWidget *dialog; + * + * dialog = gtk_file_chooser_dialog_new ("Open File", + * parent_window, + * GTK_FILE_CHOOSER_ACTION_OPEN, + * GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL, + * GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT, + * NULL); + * + * + * This will create buttons for "Cancel" and "Open" that use stock + * response identifiers from #GtkResponseType. For most dialog + * boxes you can use your own custom response codes rather than the + * ones in #GtkResponseType, but #GtkFileChooserDialog assumes that + * its "accept"-type action, e.g. an "Open" or "Save" button, + * will have one of the following response + * codes: + * + * + * #GTK_RESPONSE_ACCEPT + * #GTK_RESPONSE_OK + * #GTK_RESPONSE_YES + * #GTK_RESPONSE_APPLY + * + * + * This is because #GtkFileChooserDialog must intercept responses + * and switch to folders if appropriate, rather than letting the + * dialog terminate — the implementation uses these known + * response codes to know which responses can be blocked if + * appropriate. + * + * + * To summarize, make sure you use a + * stock response code + * when you use #GtkFileChooserDialog to ensure proper operation. + * + * + *
