GtkFileChooserDialog
is a dialog suitable for use with
“File Open” or “File Save” commands.
This widget works by putting a FileChooserWidget
inside a Dialog
. It exposes the FileChooser
interface, so you can use all of the FileChooser
functions
on the file chooser dialog as well as those for Dialog
.
Note that GtkFileChooserDialog
does not have any methods of its
own. Instead, you should use the functions that work on a
FileChooser
.
If you want to integrate well with the platform you should use the
FileChooserNative
API, which will use a platform-specific
dialog if available and fall back to GtkFileChooserDialog
otherwise.
Typical usage
In the simplest of cases, you can the following code to use
GtkFileChooserDialog
to select a file for opening:
c code
static void on_open_response (GtkDialog *dialog, int response) { if (response == GTK_RESPONSE_ACCEPT) { GtkFileChooser *chooser = GTK_FILE_CHOOSER (dialog); g_autoptr(GFile) file = gtk_file_chooser_get_file (chooser); open_file (file); } gtk_window_destroy (GTK_WINDOW (dialog)); } // ... GtkWidget *dialog; GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN; dialog = gtk_file_chooser_dialog_new ("Open File", parent_window, action, _("_Cancel"), GTK_RESPONSE_CANCEL, _("_Open"), GTK_RESPONSE_ACCEPT, NULL); gtk_window_present (GTK_WINDOW (dialog)); g_signal_connect (dialog, "response", G_CALLBACK (on_open_response), NULL);
To use a dialog for saving, you can use this:
c code
static void on_save_response (GtkDialog *dialog, int response) { if (response == GTK_RESPONSE_ACCEPT) { GtkFileChooser *chooser = GTK_FILE_CHOOSER (dialog); g_autoptr(GFile) file = gtk_file_chooser_get_file (chooser); save_to_file (file); } gtk_window_destroy (GTK_WINDOW (dialog)); } // ... GtkWidget *dialog; GtkFileChooser *chooser; GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE; dialog = gtk_file_chooser_dialog_new ("Save File", parent_window, action, _("_Cancel"), GTK_RESPONSE_CANCEL, _("_Save"), GTK_RESPONSE_ACCEPT, NULL); chooser = GTK_FILE_CHOOSER (dialog); if (user_edited_a_new_document) gtk_file_chooser_set_current_name (chooser, _("Untitled document")); else gtk_file_chooser_set_file (chooser, existing_filename); gtk_window_present (GTK_WINDOW (dialog)); g_signal_connect (dialog, "response", G_CALLBACK (on_save_response), NULL);
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, use
FileChooserActionOpen
. - To save a file for the first time, use
FileChooserActionSave
, and suggest a name such as “Untitled” withfileChooserSetCurrentName
. - To save a file under a different name, use
FileChooserActionSave
, and set the existing file withfileChooserSetFile
. - To choose a folder instead of a filem use
FileChooserActionSelectFolder
.
In general, you should only cause the file chooser to show a specific
folder when it is appropriate to use fileChooserSetFile
,
i.e. when you are doing a “Save As” command and you already have a file
saved somewhere.
Response Codes
GtkFileChooserDialog
inherits from Dialog
, so buttons that
go in its action area have response codes such as ResponseTypeAccept
and
ResponseTypeCancel
. For example, you could call
FileChooserDialog
.new
() as follows:
c code
GtkWidget *dialog; GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN; dialog = gtk_file_chooser_dialog_new ("Open File", parent_window, action, _("_Cancel"), GTK_RESPONSE_CANCEL, _("_Open"), GTK_RESPONSE_ACCEPT, NULL);
This will create buttons for “Cancel” and “Open” that use predefined
response identifiers from ResponseType
. For most dialog
boxes you can use your own custom response codes rather than the
ones in ResponseType
, but GtkFileChooserDialog
assumes that
its “accept”-type action, e.g. an “Open” or “Save” button,
will have one of the following response codes:
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 predefined response code
when you use GtkFileChooserDialog
to ensure proper operation.
CSS nodes
GtkFileChooserDialog
has a single CSS node with the name window
and style
class .filechooser
.
Synopsis
- newtype FileChooserDialog = FileChooserDialog (ManagedPtr FileChooserDialog)
- class (GObject o, IsDescendantOf FileChooserDialog o) => IsFileChooserDialog o
- toFileChooserDialog :: (MonadIO m, IsFileChooserDialog o) => o -> m FileChooserDialog
Exported types
newtype FileChooserDialog Source #
Memory-managed wrapper type.
Instances
class (GObject o, IsDescendantOf FileChooserDialog o) => IsFileChooserDialog o Source #
Type class for types which can be safely cast to FileChooserDialog
, for instance with toFileChooserDialog
.
Instances
(GObject o, IsDescendantOf FileChooserDialog o) => IsFileChooserDialog o Source # | |
Defined in GI.Gtk.Objects.FileChooserDialog |
toFileChooserDialog :: (MonadIO m, IsFileChooserDialog o) => o -> m FileChooserDialog Source #
Cast to FileChooserDialog
, for types for which this is known to be safe. For general casts, use castTo
.
