* In the simplest of cases, you can the following code to use
* #GtkFileChooserDialog to select a file for opening:
*
* |[
* GtkFileChooserNative *native;
* GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN;
* gint res;
* |[<!-- language="C" -->
* static void
* on_response (GtkNativeDialog *dialog,
* int response)
* {
* if (response == GTK_RESPONSE_ACCEPT)
* {
* GtkFileChooser *chooser = GTK_FILE_CHOOSER (native);
* GFile *file = gtk_file_chooser_get_file (chooser);
*
* native = gtk_file_chooser_native_new ("Open File",
* parent_window,
* action,
* "_Open",
* "_Cancel");
* open_file (file);
*
* res = gtk_native_dialog_run (GTK_NATIVE_DIALOG (native));
* if (res == GTK_RESPONSE_ACCEPT)
* {
* char *filename;
* GtkFileChooser *chooser = GTK_FILE_CHOOSER (native);
* filename = gtk_file_chooser_get_filename (chooser);
* open_file (filename);
* g_free (filename);
* }
* g_object_unref (file);
* }
*
* g_object_unref (native);
* g_object_unref (native);
* }
*
* // ...
* GtkFileChooserNative *native;
* GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN;
*
* native = gtk_file_chooser_native_new ("Open File",
* parent_window,
* action,
* "_Open",
* "_Cancel");
*
* g_signal_connect (native, "response", G_CALLBACK (on_response), NULL);
* gtk_native_dialog_show (GTK_NATIVE_DIALOG (native));
* ]|
*
* To use a dialog for saving, you can use this:
*
* |[
* GtkFileChooserNative *native;
* GtkFileChooser *chooser;
* GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE;
* gint res;
* |[<!-- language="C" -->
* static void
* on_response (GtkNativeDialog *dialog,
* int response)
* {
* if (response == GTK_RESPONSE_ACCEPT)
* {
* GtkFileChooser *chooser = GTK_FILE_CHOOSER (dialog);
* GFile *file = gtk_file_chooser_get_file (chooser);
*
* native = gtk_file_chooser_native_new ("Save File",
* parent_window,
* action,
* "_Save",
* "_Cancel");
* chooser = GTK_FILE_CHOOSER (native);
* save_to_file (file);
*
* if (user_edited_a_new_document)
* gtk_file_chooser_set_current_name (chooser,
* g_object_unref (file);
* }
*
* g_object_unref (native);
* }
*
* // ...
* GtkFileChooserNative *native;
* GtkFileChooser *chooser;
* GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE;
*
* native = gtk_file_chooser_native_new ("Save File",
* parent_window,
* action,
* "_Save",
* "_Cancel");
* chooser = GTK_FILE_CHOOSER (native);
*
* if (user_edited_a_new_document)
* gtk_file_chooser_set_current_name (chooser,
* _("Untitled document"));
* else
* gtk_file_chooser_set_filename (chooser,
* existing_filename);
* else
* gtk_file_chooser_set_filename (chooser,
* existing_filename);
*
* res = gtk_native_dialog_run (GTK_NATIVE_DIALOG (native));
* if (res == GTK_RESPONSE_ACCEPT)
* {
