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
Assignee: wine-bugs at winehq.org
Reporter: contact at kcsoftwares.com
Distribution: ---
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.
