tMultiget and bLostFocus problem

Posted: Wed Jan 12, 2011 09:01 AM

Hi all,
it is a bit strange problem that didn't exist on the FWH Oct 2009.
if a make (in a multiget) a oGet:bLostfocus:={......} then when the bLostFocus is evaluated the new get value is not still assigned
different from FWH Oct 2009 where the get was assigned.

I tried to bypass the problem with oGet:Assign() after the bLostFocus is evaluated but this method is not available in tMultiget class.

Any ideas ? Thanks in advance.

Best Regards,

This is the code of LostFocus method in multiget class

Code (fw): Select all Collapse

//----------------------------------------------------------------------------//

METHOD LostFocus( hCtlFocus ) CLASS TMultiGet

   Super:LostFocus( hCtlFocus )

   if ::bSetGet != nil
      Eval( ::bSetGet, GetWindowText( ::hWnd ) )
   endif

   ::nPos = nLoWord( ::SendMsg( EM_GETSEL ) )

return nil

//----------------------------------------------------------------------------//

Super:LostFocus(...) evaluate bLostFocus codeblock. By this time the buffer is still not assigned to the variable. This is the same code even in 10.07. I do not know why there is any change in the behavior between 10.07 ( or 10.09 ) and now.

In any case try moving the line Super:LostFocus(..) next to the If ::bSetGet .... endif block.

This should give the desired behavior for you. Let us see if this solution works well and has no other undesirable side-effects.

Alternatively, keep the following line as the first line of your bLostFocus code block

Code (fw): Select all Collapse

     Eval( oGet:bSetGet, GetWindowText( oGet:hWnd ) )

Hi,
moving Super:LostFocus( hCtlFocus ) all seems to runs well.

I checked that LostFocus method is unchanged beetween Fwh oct 2009 and Fwh Nov 2010
so I think this issue is related to other changes in mget or other "core" FWH classes.

Thanks for your quick support.

Probably it may not be a good idea to change the class in FWH library.

Instead better we insert this line as the first line of our bLostFocus code

Code (fw): Select all Collapse

   Eval( oGet:bSetGet, oGet:GetText() )

Yes, I generally avoid to make changes to the fwh classes but this seem to be a bug so a correction of the mget module is needed,
I think the tmultiget has to works with the same tGet logic so the value has to be automatically assigned when the lostfocus is valuated.
