In the following sample, VALID clause is not fired when the combobox losts the focus:

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL oCbx, cVar := SPACE( 20 )

    DEFINE DIALOG oDlg

    @ 1, 1 COMBOBOX oCbx VAR cVar;
           ITEMS { "First", "Second", "Third" };
           STYLE CBS_DROPDOWN;
           VALID ( MSGINFO( "Valid" ), .T. )

    @ 3, 1 BUTTON "&Close" ACTION oDlg:End()

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL

Enrico,
not fired when the combobox lost the focus but fired when the button lost the focus!

Ciao, best regards,

Ugo

Enrico,

I'm afraid I can't help. I gave up on valid's with comboboxes about 10 years ago after raising the problem many times. I came up with a fix back then (IIRC it required change to CONTROL and also to DEFAULT method in COMBOBOX.prg) but I can no longer find it and it got broken in a subsequent upgrade anyway. I'm not convinced valid on a combobox (without modifications) has ever completely worked (although I could be wrong).

As an aside, although I can confirm the bug you reported, I suggest you avoid using MSGINFO() to test for a VALID as that can shift the focus to the MSGINFO(). I use something like MSGBEEP() instead.

No problem friends. I reported it only for Antonio. I don't need that fix at all.
