Combobox Problem

[cdmmaui]

Hello,

When the user presses a character to move to the item within a COMBOBOX, it does not work. I updated to version 7.01.

I noticed that too.

To solve it for the moment, I linked in the COMBOBOX.PRG from FW 2.7.

Now it's working fine.

Regards,

Michel

Hi Michel,

Thank you. Can you send me the 2.7 PRG as I over wrote my version with the update.

[driessen]

No problem.

Here it is.

Just copy and paste and you've got is.

Yes, confirm!

for solve, replace the method KeyChar with this:

Code: Select all

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

METHOD KeyChar( nKey, nFlags ) CLASS TComboBox

   local nNewAT := 0, nOldAT := ::nAT, uItem

   do case
      case nKey = 32   // VK_DELETE (DO NOT WORK!)
           ::cSearchKey := ""
           nNewAt := 1
           uItem := ::aItems[nNewAt]
           
      case nKey = VK_BACK
           ::cSearchKey := Left( ::cSearchKey, Len( ::cSearchKey ) - 1 )
           
      case nKey = 190
           nKey := 0
           ::cSearchKey += "."
           
      otherwise
           ::cSearchKey += Upper( Chr( nKey ) )
           
   endcase
   
   if Empty( uItem )
      if nNewAt == 0
         nNewAt := AScan( ::aItems, {|x| Upper(x) = ::cSearchKey } )
         IF nNewAt > 0 .AND. Len( ::aItems ) <= nNewAt
            uItem := ::aItems[ nNewAt ]
         ENDIF
         uItem := ::aItems[ IIF( nNewAt > 0, nNewAt, Max( ::nAT, 1 ) ) ]
      else
         uItem := ::aItems[ Max( nNewAt, 1) ]
      endif
   endif
   ::Set( uItem )

   if ::bChange != nil .and. ( nNewAT != nOldAt .and. nNewAt != 0 )
      Eval( ::bChange, Self, ::varGet() )
   endif

   if nKey == VK_RETURN
      return ::oWnd:GoNextCtrl( ::hWnd )
   endif

return 0   // Must be 0 - We don't want API default behavior.

FWH 7.01 implements incremental search in comboboxes, thats why if you press two chars, one after another, if searches for the item that starts with both chars (implemented by Ugo).

Ugo, thanks for the fix
