/**
* SECTION:gtkfilechoosernative
* @Short_description: A native file chooser dialog, suitable for File/Open or File/Save commands
* @Title: GtkFileChooserNative
* @See_also: #GtkFileChooser, #GtkNativeDialog, #GtkFileChooserDialog
*
* #GtkFileChooserNative is an abstraction of a dialog box suitable
* for use with File/Open or File/Save as commands. By default, this
* just uses a #GtkFileChooserDialog to implement the actual dialog.
* However, on certain platforms, such as Windows and macOS, the native platform
* file chooser is used instead. When the application is running in a
* sandboxed environment without direct filesystem access (such as Flatpak),
* #GtkFileChooserNative may call the proper APIs (portals) to let the user
* choose a file and make it available to the application.
*
* While the API of #GtkFileChooserNative closely mirrors #GtkFileChooserDialog, the main
* difference is that there is no access to any #GtkWindow or #GtkWidget for the dialog.
* This is required, as there may not be one in the case of a platform native dialog.
* Showing, hiding and running the dialog is handled by the #GtkNativeDialog functions.
*
* ## Typical usage ## {#gtkfilechoosernative-typical-usage}
*
* 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;
*
* native = gtk_file_chooser_native_new ("Open File",
* parent_window,
* action,
* "_Open",
* "_Cancel");
*
* 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 (native);
* ]|
*
* To use a dialog for saving, you can use this:
*
* |[
* GtkFileChooserNative *native;
* GtkFileChooser *chooser;
* GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE;
* gint res;
*
* native = gtk_file_chooser_native_new ("Save File",
* parent_window,
* action,
* "_Save",
* "_Cancel");
* chooser = GTK_FILE_CHOOSER (native);
*
* gtk_file_chooser_set_do_overwrite_confirmation (chooser, TRUE);
*
* if (user_edited_a_new_document)
* gtk_file_chooser_set_current_name (chooser,
* _("Untitled document"));
* else
* gtk_file_chooser_set_filename (chooser,
* existing_filename);
*
* res = gtk_native_dialog_run (GTK_NATIVE_DIALOG (native));
* if (res == GTK_RESPONSE_ACCEPT)
* {
* char *filename;
*
* filename = gtk_file_chooser_get_filename (chooser);
* save_to_file (filename);
* g_free (filename);
* }
*
* g_object_unref (native);
* ]|
*
* For more information on how to best set up a file dialog, see #GtkFileChooserDialog.
*
* ## Response Codes ## {#gtkfilechooserdialognative-responses}
*
* #GtkFileChooserNative inherits from #GtkNativeDialog, which means it
* will return #GTK_RESPONSE_ACCEPT if the user accepted, and
* #GTK_RESPONSE_CANCEL if he pressed cancel. It can also return
* #GTK_RESPONSE_DELETE_EVENT if the window was unexpectedly closed.
*
* ## Differences from #GtkFileChooserDialog ## {#gtkfilechooserdialognative-differences}
*
* There are a few things in the GtkFileChooser API that are not
* possible to use with #GtkFileChooserNative, as such use would
* prohibit the use of a native dialog.
*
* There is no support for the signals that are emitted when the user
* navigates in the dialog, including:
* * #GtkFileChooser::current-folder-changed
* * #GtkFileChooser::selection-changed
* * #GtkFileChooser::file-activated
* * #GtkFileChooser::confirm-overwrite
*
* You can also not use the methods that directly control user navigation:
* * gtk_file_chooser_unselect_filename()
* * gtk_file_chooser_select_all()
* * gtk_file_chooser_unselect_all()
*
* If you need any of the above you will have to use #GtkFileChooserDialog directly.
*
* No operations that change the the dialog work while the dialog is
* visible. Set all the properties that are required before showing the dialog.
*
* ## Win32 details ## {#gtkfilechooserdialognative-win32}
*
* On windows the IFileDialog implementation (added in Windows Vista) is
* used. It supports many of the features that #GtkFileChooserDialog
* does, but there are some things it does not handle:
*
* * Extra widgets added with gtk_file_chooser_set_extra_widget().
*
* * Use of custom previews by connecting to #GtkFileChooser::update-preview.
*
* * Any #GtkFileFilter added using a mimetype or custom filter.
*
* If any of these features are used the regular #GtkFileChooserDialog
* will be used in place of the native one.
*
* ## Portal details ## {#gtkfilechooserdialognative-portal}
*
* When the org.freedesktop.portal.FileChooser portal is available on the
* session bus, it is used to bring up an out-of-process file chooser. Depending
* on the kind of session the application is running in, this may or may not
* be a GTK+ file chooser. In this situation, the following things are not
* supported and will be silently ignored:
*
* * Extra widgets added with gtk_file_chooser_set_extra_widget().
*
* * Use of custom previews by connecting to #GtkFileChooser::update-preview.
*
* * Any #GtkFileFilter added with a custom filter.
*
* ## macOS details ## {#gtkfilechooserdialognative-macos}
*
* On macOS the NSSavePanel and NSOpenPanel classes are used to provide native
* file chooser dialogs. Some features provided by #GtkFileChooserDialog are
* not supported:
*
* * Extra widgets added with gtk_file_chooser_set_extra_widget(), unless the
* widget is an instance of GtkLabel, in which case the label text will be used
* to set the NSSavePanel message instance property.
*
* * Use of custom previews by connecting to #GtkFileChooser::update-preview.
*
* * Any #GtkFileFilter added with a custom filter.
*
* * Shortcut folders.
