Hi Sebastian,

PMFJI,
The gap on height is some extra space around the first and last line.
In Thread#621982 Message#622409 I found a way to calculate this gap. This is for an editbox but should work for Listbox also.

lnWidth = TXTWIDTH( m.MyText, cFontName, nFontSize , cFontStyle ) ;

NOTE: Do never forget to specify all font parameters!
