Window locations in Forms4

Is there any way of determining how big the display is from within Forms4 and MS Windows? It is possible to set the size of the container(MDI) window using set_window_property with the forms_mdi_window constant, however I can't see a way of determining what the available space is.

A portable solution would be best (ie. MS Windows, Motif and Macintosh), however an MS Windows solution would be a start.

Also, is there any way of getting information about the MDI window? The get_window_property built-in doesn't seem to work with the MDI constants. This only applies to MS Windows of course.

Thanks in advance.
