Interfaces

GtkFileChooserDialog implements AtkImplementorIface, GtkBuildable and GtkFileChooser.

Detailed Description

GtkFileChooserDialog is a dialog box suitable for use with "File/Open" or "File/Save as" commands. This widget works by putting a GtkFileChooserWidget inside a GtkDialog. It exposes the GtkFileChooserIface interface, so you can use all of the GtkFileChooser functions on the file chooser dialog as well as those for GtkDialog. Note that GtkFileChooserDialog does not have any methods of its own. Instead, you should use the functions that work on a GtkFileChooser. Typical usage

######
# Request a file from the user and open it
###### # This is how one creates a dialog with buttons and associated response codes.
# (Please ignore the C "Response Code" example in the next section)
dialog <- gtkFileChooserDialog("Open File", parent_window, "open",
                               "gtk-cancel", GtkResponseType["cancel"], 
                               "gtk-open", GtkResponseType["accept"]) if (dialog$run() == GtkResponseType["accept"]) {
  filename <- dialog$getFilename()
  f <- file(filename)
} dialog$destroy()

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 gtkFileChooserDialogNew 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. PLEASE NOTE: To summarize, make sure you use a stock response code when you use GtkFileChooserDialog to ensure proper operation.

Structures

Convenient Construction

gtkFileChooserDialog is the result of collapsing the constructors of GtkFileChooserDialog (gtkFileChooserDialogNew, gtkFileChooserDialogNewWithBackend) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.
