Summary: WM_HELP sent at wrong time; needs to support 0x4d
message
Product: Wine
Version: 20030508
Platform: All
OS/Version: Linux
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: wine-user
AssignedTo: wine-bugs at winehq.com
ReportedBy: jr-winebugs at quo.to
For consistency with Windows (95 and 2000, at least), when you press F1 on a
control, it should not immediately send a WM_HELP message to the control as it
does now (see process_cooked_keyboard_message() in windows/message.c). Rather,
it should _post_ an 0x4d message to itself with wParam=0 and lParam=0.
DefWindowProc should then handle 0x4d by sending a WM_HELP message.
0x4d seems to be undocumented but is still useful to third-party apps: they can
swallow 0x4d messages in their message loop to prevent WM_HELP messages from
being sent.
