Can you please explain why updating it is a problem? Yes, we may be
doing more work than needed, but at most it should be a no-op.
In fact, we used to call 'GetWindowLongW(hwnd, GWL_STYLE)' every
time we needed to get to the dwStyle, so updating it in there
should be OK.
Unfortunetly I can't explain it, because I don't understand it myself. I
have inserted debug messages on all the places where the listview
display mode can be changed and none of them appeared. After going once
more through the whole code I found this. Obviously it seemed redundant
and the only reason for doing that was workarounding problems with
changed WS_VSCROLL and WS_HSCROLL styles (which correctly don't recieve
WM_STYLECHANGED notifications from the scrolling code). So I tried
removing it and ... whoa ... to my surprise it started to work.
BTW, I've tried to install the demo, but the installer dies on my
version of wine. Does it work for you, or did you use Windows for
the installation?
Yes, I installed it on Windows and even most of done most of the testing
on Windows with Wine COMCTL32. Before sending the patch to wine-patches
I checked if it works as desired on Wine...
