      void onComputeSize(@Nonnull ch.bailu.gtk.gdk.ToplevelSize size)
      Emitted when the size for the surface needs to be computed, when
      it is present.

      It will normally be emitted during or after [method@Gdk.Toplevel.present],
      depending on the configuration received by the windowing system.
      It may also be emitted at any other point in time, in response
      to the windowing system spontaneously changing the configuration.

      It is the responsibility of the toplevel user to handle this signal
      and compute the desired size of the toplevel, given the information
      passed via the [struct@Gdk.ToplevelSize] object. Failing to do so
      will result in an arbitrary size being used as a result.
      Parameters:
      size - a `GdkToplevelSize`
