Hi all,

i am using BB under wine, and the /NOSCROLL command line option didn't work for me: i would always get scroll bars when a window was moved beyond main client area. Under Windows, this was not the case: the /NOSCROLL works just fine.

Recently i found a bug fix for Wine that solves the problem. It's discussion can be found here:
http://bugs.winehq.org/show_bug.cgi?id=9453

For convenience, i will post the patch itself at the end of this email.

To apply it, you will need wine source code, of course, then apply the patch file to mdi.c in the source tree (unless in your version it is already included), then:
IF you haven't built wine before THEN
   build wine with "make && make install" or following insructions in README
ELSIF you have the file mdi.o (* from a previous build *) THEN
   remove or rename mdi.o
   from wine source root run "make".
        (* this will make a new version of user32.dll.so in the source tree *)
   locate "user32.dll.so" in your local filesystem
   replace the "user32.dll.so" in your local filesystem with the newly make'd
user32.dll.so"
END

Restart BB and enjoy!

Here is the patch:
----------------------------------------------------
Index: mdi.c
===================================================================
--- mdi.c (revision 12767)
+++ mdi.c (arbetskopia)
{([at]})nowhere.xy
     UINT nTotalCreated;
     UINT mdiFlags;
     UINT sbRecalc; /* SB_xxx flags for scrollbar fixup */
+ DWORD initialStyle; /* Style when window was created */
 } MDICLIENTINFO;
 
 static HBITMAP hBmpClose = 0;
{([at]})nowhere.xy
         ci->nTotalCreated = 0;
         ci->frameTitle = NULL;
         ci->mdiFlags = 0;
+ ci->initialStyle = cs->style;
         ci->hFrameMenu = GetMenu(cs->hwndParent);
 
         if (!hBmpClose) hBmpClose = CreateMDIMenuBitmap();
{([at]})nowhere.xy
     SCROLLINFO info;
     RECT childRect, clientRect;
     HWND *list;
+ MDICLIENTINFO *ci;
 
+ ci = get_client_info(hwnd);
     GetClientRect( hwnd, &clientRect );
     SetRectEmpty( &childRect );
 
{([at]})nowhere.xy
                         info.nMin = childRect.left;
                         info.nMax = childRect.right - clientRect.right;
                         info.nPos = clientRect.left - childRect.left;
- SetScrollInfo(hwnd, SB_HORZ, &info, TRUE);
+ if (ci->initialStyle & WS_HSCROLL)
+ SetScrollInfo(hwnd, SB_HORZ, &info, TRUE);
                         if (scroll == SB_HORZ) break;
                         /* fall through */
         case SB_VERT:
                         info.nMin = childRect.top;
                         info.nMax = childRect.bottom - clientRect.bottom;
                         info.nPos = clientRect.top - childRect.top;
- SetScrollInfo(hwnd, SB_VERT, &info, TRUE);
+ if (ci->initialStyle & WS_VSCROLL)
+ SetScrollInfo(hwnd, SB_VERT, &info, TRUE);
                         break;
     }
 }
