Expand description
Use FileDialog
instead
FileChooserDialog
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 FileChooserDialog
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 FileChooserDialog
otherwise.
Typical usage
In the simplest of cases, you can the following code to use
FileChooserDialog
to select a file for opening:
⚠️ The following code is in c ⚠️
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:
⚠️ The following code is in c ⚠️
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 FileChooserDialog
:
-
To select a file for opening, use
FileChooserAction::Open
. -
To save a file for the first time, use
FileChooserAction::Save
, and suggest a name such as “Untitled” withFileChooserExt::set_current_name()
. -
To save a file under a different name, use
FileChooserAction::Save
, and set the existing file withFileChooserExt::set_file()
. -
To choose a folder instead of a filem use
FileChooserAction::SelectFolder
.
In general, you should only cause the file chooser to show a specific
folder when it is appropriate to use FileChooserExt::set_file()
,
i.e. when you are doing a “Save As” command and you already have a file
saved somewhere.
Response Codes
FileChooserDialog
inherits from Dialog
, so buttons that
go in its action area have response codes such as ResponseType::Accept
and
ResponseType::Cancel
. For example, you could call
new()
as follows:
⚠️ The following code is in c ⚠️
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 FileChooserDialog
assumes that
its “accept”-type action, e.g. an “Open” or “Save” button,
will have one of the following response codes:
This is because FileChooserDialog
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 FileChooserDialog
to ensure proper operation.

Implementations§
source§impl FileChooserDialog
impl FileChooserDialog
sourcepub fn builder() -> FileChooserDialogBuilder
pub fn builder() -> FileChooserDialogBuilder
Creates a new builder-pattern struct instance to construct FileChooserDialog
objects.
This method returns an instance of FileChooserDialogBuilder
which can be used to create FileChooserDialog
objects.

.
This function is analogous to Dialog::with_buttons()
.
