Determine ListView/ListBox Height at Runtime

Hi,

I was wondering if anyone knew of a "cast iron" way to precisely determine the required height of a ListView/ListBox item at runtime based upon the number of rows in the list.

I looked at the "FontSize" and "IconYSpacing" properties eg (setq Height (* (dcl-ListView-GetCount ListView)(dcl-Control-GetProperty ListView "IconYSpacing"))). 

I could try to concoct an agorithm through trial and error, but I was wondering if there was a better way?

I think that will be rather difficult. You'll also need to account for screen resolution, themes, and user settings affecting the sizes of various parts of the controls.

Ok, thanks Owen. :(
