Signal Details

The "compute-size" signal

lambda (toplevel size)    :run-last

toplevel: The gdk:toplevel object.
size: The gdk:toplevel-size instance.

Compute the desired size of the toplevel, given the information passed via the gdk:toplevel-size instance. It will normally be emitted during or after the gdk:toplevel-present function, 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. Failing to do so will result in an arbitrary size being used as a result.
