--- Comment #4 from Florian florian@fkoeberle.de 2011-10-20 16:17:37 CDT --- Well the idea of the test is to show that having a column with the same size as the listview should not result in a visible scrollbar. I used the test bot to validate that windows does indeed behave that way.
I am not sure what you are asking about with "Does is use LVS_NOSCROLL", but as the test shows that windows doesn't show a scrollbar in that particular case even without any LVS_NOSCROLL flags.
I think too that the width calculation is wrong, but I kept the test that way since I am unsure of how to get the calculated width. It's propably totally easy but I don't know how to do it and would have to dig trough MSDN documentation.
So should I try to find out how to get the calculated width or do you want to write a proper test and patch?
