Close problem

When the (query)close method(s) of a standard shell are called, the
user gets the option to say Don't close, the queryclose returns false
and the user can go on.

Unfortunately, any open datawindow's (query)close method(s) have been
called BEFORE the (query)close method(s) of the shell and everything
shut down there remains shut down which will lead to errors.

Is it preventable that the (query)close method(s) of datawindows are
called before the the owning shell allows closing?

Dick,

METHOD Dispatch(oEvent) CLASS HoofdShellWin

// Deze methode zorgt ervoor dat de user een confirm-on-exit box krijgt
als hij het shell

// window sluit. NB: via de Queryclose gaat niet, want dan wordt ook de
queryclose van

// elke childwindow gedaan!



LOCAL oEvt := oEvent AS Event

LOCAL uMsg AS DWORD

uMsg := oEvt:uMsg

DO CASE

CASE (uMsg == WM_QUERYENDSESSION) .OR. (uMsg == WM_CLOSE)

// we prompten de user of hij echt wil sluiten:

IF PDBProceed("Close", "Do you want to close this application?")


ELSE

RETURN 1L // =niet afsluiten

ENDIF

ENDCASE

RETURN SUPERispatch(oEvt)

That's quick and that seems indeed to 'reverse' the order of closing
windows. Thanks!

Paul,

What issues a WM_QUERYENDSESSION?

I've been trying this on a SplitWindow by clicking the X and using the
standard Close method but I don't see this event.

Do you know what should be trying to issue this?

Ah! No wonder we don't see it.

Well, we don't care either then <g>. If things get that far then
everything is about to be collapsed so nothing actually matters any
more.
