Bug ID: 49097
           Summary: Treeview unduly handles WM_SYSKEYDOWN
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: comctl32

Treeview unduly handles WM_SYSKEYDOWN

Refer to treeview.c
    case WM_KEYDOWN:
    case WM_SYSKEYDOWN:
    return TREEVIEW_KeyDown(infoPtr, wParam);

No such processing on Listview : 
  case WM_KEYDOWN:
    return LISTVIEW_KeyDown(infoPtr, (INT)wParam, (LONG)lParam);

As a consequence, WM_SYSKEYDOWN not correctly passed to parent Wnd if focus is
on a Treeview control.

Proof of concept : Use ReactOS. Open Regedit or Event Viewer. Put focus on
treeview. Alt+F4 does nothing (WM_SYSKEYDOWN "stuck" at Treeview component
level)

Suggested patch : 
change
    case WM_KEYDOWN:
    case WM_SYSKEYDOWN:
    return TREEVIEW_KeyDown(infoPtr, wParam);
into
    case WM_KEYDOWN:
    return TREEVIEW_KeyDown(infoPtr, wParam);

as no reason to handle WM_SYSKEYDOWN at component level.
