Bug in TButton

[Enrico Maria Giordano]

The following sample shows the problem. Try to put any character in the GET and then hit ALT-C. You will see that the DIALOG won't close. On the contrary, if you click on the button the DIALOG will close.

Code: Select all

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVar := SPACE( 20 )

    DEFINE DIALOG oDlg

    @ 1, 1 GET cVar;
           VALID !EMPTY( cVar )

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

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL

Enrico,

On a first review it looks as a Harbour vs xharbour related issue.

With Harbour it works ok

It seems a difference between Harbour/xharbour Class TGet.

[Antonio Linares]

This way it works:

Code: Select all

    @ 1, 1 GET cVar; 
           VALID ( oDlg:aControls[ 1 ]:Assign(), !EMPTY( cVar ) ) 

So it seems that with xharbour the ::oGet DATA has not been assigned, thats why it remains "empty".

[Antonio Linares]

This is a fix:

Code: Select all

METHOD lValid() CLASS TGet

   local lRet := .t.

   if ::oGet:BadDate
      ::oGet:KillFocus()
      ::oGet:SetFocus()
      MsgBeep()
      return .f.
   else
      ::oGet:Assign()    // New !!!
      if ValType( ::bValid ) == "B"
         lRet := Eval( ::bValid, Self  )
         if ! lRet
            ::oWnd:nLastKey = 0
         endif
      endif
   endif

return lRet

Thank you, but I suspect that some other problems is hiding under the wood...

Enrico,

Yes, we'll see.

The problem is that Class TGet is quite different from Harbour to xharbour.

Antonio:

The last time I sent you a suggested fix in TGet [I forgot what it was
about ], I pasted a modified version of ::EditUpdate() I've been using for several years now and in which I added the call to ::oGet:assign()
to ensure the Clipper/[x]Harbour buffer was always in sync with FW/FWH's.
That could be an alternate fix for this problem:

METHOD EditUpdate() CLASS TGet

if ::oGet:HasFocus
::DispText()
::oGet:Assign() // lkm
endif

::SetPos( ::oGet:Pos )

Return Self

This is a fix:

Code: Select all

METHOD lValid() CLASS TGet

   local lRet := .t.

   if ::oGet:BadDate
      ::oGet:KillFocus()
      ::oGet:SetFocus()
      MsgBeep()
      return .f.
   else
      ::oGet:Assign()    // New !!!
      if ValType( ::bValid ) == "B"
         lRet := Eval( ::bValid, Self  )
         if ! lRet
            ::oWnd:nLastKey = 0
         endif
      endif
   endif

return lRet

Code: Select all

Enrico,

Yes, we'll see.

The problem is that Class TGet is quite different from Harbour to xharbour.

After some tests it seems all ok with your fix.

Thank you.

Luis,

The fact is that Class TGet is different in Harbour and xharbour, thats why we need to asure that before we validate a GET, its related variable has been assigned. Placing it at lValid() is a way to be sure it gets done.
