Class

Gtk.MessageDialog

Description [src]

final class Gtk.MessageDialog : Gtk.Dialog {
  parent_instance: GtkDialog
}

GtkMessageDialog presents a dialog with some message text.

An example GtkMessageDialog

It’s simply a convenience widget; you could construct the equivalent of GtkMessageDialog from GtkDialog without too much effort, but GtkMessageDialog saves typing.

The easiest way to do a modal message dialog is to use the GTK_DIALOG_MODAL flag, which will call gtk_window_set_modal() internally. The dialog will prevent interaction with the parent window until it’s hidden or destroyed. You can use the GtkDialog::response signal to know when the user dismissed the dialog.

An example for using a modal dialog:

GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT | GTK_DIALOG_MODAL;
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 (dialog, "response",
                  G_CALLBACK (gtk_window_destroy),
                  NULL);

You might do a non-modal GtkMessageDialog simply by omitting the GTK_DIALOG_MODAL flag:

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 (dialog, "response",
                  G_CALLBACK (gtk_window_destroy),
                  NULL);

GtkMessageDialog as GtkBuildable

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