true

function true():Boolean {
    // Gjs wrapper for gtk_true()
}

All this function does it to return true.

This can be useful for example if you want to inhibit the deletion of a window. Of course you should not do this as the user expects a reaction from clicking the close icon of the window...

<example> <title>A persistent window</title> <programlisting> #include &lt;gtk/gtk.h>&lt;

int main (int argc, char **argv) { GtkWidget *win, *but;

gtk_init (&amp;argc, &amp;argv);

win = gtk_window_new (GTK_WINDOW_TOPLEVEL); g_signal_connect (win, "delete-event", G_CALLBACK (gtk_true), NULL); g_signal_connect (win, "destroy", G_CALLBACK (gtk_main_quit), NULL);

but = gtk_button_new_with_label ("Close yourself. I mean it!"); g_signal_connect_swapped (but, "clicked", G_CALLBACK (gtk_object_destroy), win); gtk_container_add (GTK_CONTAINER (win), but);

gtk_widget_show_all (win);

gtk_main ();

return 0; } </programlisting> </example>
