Reliable messages and their meanings (note that any message may be missed if bug.n is hung):
|
||||
1 - Window shown (shown ID)
|
||||
2 - Window destroyed or hidden, same message for both (destroyed or hidden ID)
|
||||
4 - Window activated via mouse, alt+tab, or hotkey (sometimes 32772, but always one of them)
|
||||
6 - Window title change (ID of redrawn window)
|
||||
13 - Hung window recovers and replaces ghost window (ghost window ID is provided)
|
||||
14 - Hung window recovered (ID of previously hung window)
|
||||
32772 - Window activated via mouse, alt+tab, or hotkey (sometimes 4, but always one of them)
|
||||
32774 - Window is flashing due to some event, one message for each flash
|
||||
|
||||
Indications of:
|
||||
New windows
|
||||
cmd/shell may be starting a new window on message 6
|
||||
Win+e indicates a new window with message 6 as long as the button
|
||||
presses are below a certain frequency.
|
||||
Message 1 may indicate a new window started from Windows Explorer.
|
||||
Possible indications for a ...
|
||||
new window: 1 (started by Windows Explorer) or 6 (started by cmd, shell or Win+E).
|
||||
There doesn't seem to be a reliable way to get all application starts.
|
||||
Closed windows
|
||||
13 always indicates closed ghost window
|
||||
2 always indicates closed standard window
|
||||
Focus change
|
||||
4 or 32772 always catch this
|
||||
Window event
|
||||
6 indicates when title changes which can be used
|
||||
in the case of some applications, 32774 works for others
|
||||
Windows events can't always be caught.
|
||||
closed window: 2 (always?) or 13 (ghost)
|
||||
focus change: 4 or 32772
|
||||
title change: 6 or 32774
