- * gdk_surface_show:
- * @surface: a #GdkSurface
- *
- * Like gdk_surface_show_unraised(), but also raises the surface to the
- * top of the surface stack (moves the surface to the front of the
- * Z-order).
- *
- * This function maps a surface so it’s visible onscreen. Its opposite
- * is gdk_surface_hide().
- *
- * This function may not be used on a #GdkSurface with the surface type
- * GTK_SURFACE_POPUP.
- *
- * When implementing a #GtkWidget, you should call this function on the widget's
- * #GdkSurface as part of the “map” method.
