I think I usually don't do it in the WindowCreatedEvent. Do it when you first
recognize the window as something worth working with. If a window is created
that never reaches that point, because it's the wrong window or because
it's destroyed before you can get to it, nothing lost this way.

Hi Doug,
Thanks, would you always do the caching in WindowCreatedEvent, or could you
feasibly do itin any other event?
Cheers
Sean.

Subject: [jawsscripts] Re: a quick window destroyed event query
Using the WindowDestroyedEvent is tricky because all the information about the
window can be gone by the time the event fires. I rarely use that event for
this reason; and when I do, I also usually cache window handles from elsewhere
so I can recognize when the window that's going away is one I was watching for.
An overly simple example:
globals collection gMyWindows
void function WindowCreatedEvent(handle hwnd, ...) if getWindowClass(hwnd) ==
"blah"
if !gMyWindows
gMyWindows = new collection
endIf
gMyWindows[intToString(hwnd)] = 1
endIf
windowCreatedEvent(hwnd, ...)
endFunction
void function WindowDestroyedEvent(handle hwnd) if gMyWindows[intToString(hwnd)]
collectionRemoveItem(gMyWindows, intToString(hwnd))
sayString("There goes one!")
endIf
windowDestroyedEvent(hwnd)
endFunction

Hi,
I'm having to use WindowDestroyedEvent to perform some logic, but am getting an
invalid window hasndle when I try and get the class. Does anyone know whythis
is happening and whether there are any work arounds?
Cheers
Sean.
