GI.Gtk.Objects.MessageDialog

Description

MessageDialog presents a dialog with some message text. It’s simply a convenience widget; you could construct the equivalent of MessageDialog from Dialog without too much effort, but MessageDialog saves typing.

One difference from Dialog is that MessageDialog sets the Window:skip-taskbar-hint property to True, so that the dialog is hidden from the taskbar by default.

The easiest way to do a modal message dialog is to use dialogRun, though you can also pass in the DialogFlagsModal flag, dialogRun automatically makes the dialog modal and waits for the user to respond to it. dialogRun returns when any dialog button is clicked.

An example for using a modal dialog:

C code

GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
dialog = gtk_message_dialog_new (parent_window,
                                 flags,
                                 GTK_MESSAGE_ERROR,
                                 GTK_BUTTONS_CLOSE,
                                 "Error reading “%s”: %s",
                                 filename,
                                 g_strerror (errno));
gtk_dialog_run (GTK_DIALOG (dialog));
gtk_widget_destroy (dialog);

You might do a non-modal MessageDialog as follows:

An example for a non-modal dialog:

C code

GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
dialog = gtk_message_dialog_new (parent_window,
                                 flags,
                                 GTK_MESSAGE_ERROR,
                                 GTK_BUTTONS_CLOSE,
                                 "Error reading “%s”: %s",
                                 filename,
                                 g_strerror (errno));

// Destroy the dialog when the user responds to it
// (e.g. clicks a button)

g_signal_connect_swapped (dialog, "response",
                          G_CALLBACK (gtk_widget_destroy),
                          dialog);

GtkMessageDialog as GtkBuildable

The GtkMessageDialog implementation of the GtkBuildable interface exposes the message area as an internal child with the name “message_area”.
