I also altered LISTVIEW_GetSubItemRect so that it reports correct values, as compared against WinNT on ControlSpy.
Problem is that LISTVIEW_GetSubItemRect is documented to return same thing for LVIR_LABEL and LVIR_BOUNDS. Of course, incorrect documentation is known to exist, so as long as you checked it...
However, when we implement things different from the documented behavior, a clear comment explaining why we deviate is appropriate. Otherwise, someone might get rid of it in the future. :(
Well well... I had not read the docs that closely. I did not expect the definition of LVIR_LABEL to depend on what function used it.
This might require that I do a bit more testing. I had noticed that LISTVIEW_GetSubItemRect was only specified for use with a "one-based index of the subitem", but it works fine on WinNT with subitem '0', the first item.
A little more testing shows that with subitem '0', LISTVIEW_GetSubItemRect succeeds with LVIR_SELECTBOUNDS too, but that item fails for any other subitem. So I suspect the correct behavior is for subitem '0' to pass the request on to LISTVIEW_GetItemRect. For non zero subitems I may need to try to get icons inserted into another column to test with.
