A negative Width value??
I can hear it now:
Are you insane Mladen?? Do you want our apps going around looking ugly??
Well... of course I do! It means i can go around fixing them for big bucks :))
But joking aside, -1 and -2 width values are very usefull.
Setting the width to be -1 means that the column will have the width of the longest item in it.
Setting the width to be -2 means that the column will have the width of the column heading.
Pretty cool, no?
