[Lazarus] How to get real width of grid columns?

[Gabor Boros]

Hi All,

I want to save and load state(width,visibility,...) of columns. My 
problem is Width property give back 0 value from invisible columns. 
FWidth contains the real value. How to access the value?
 From my POV this is a bug, column width and visibility is two different 
things.
