Hi,

I've got some child dialogs that have single controls on them, in which case vk_tab does not do anything, but the class doesn't return it either.

I made these modifications:

tget.prg

Code: Select all

Method KeyChar

...
      case nKey == VK_TAB .and. GetKeyState( VK_SHIFT )
           // AS 23/07/2007 Changes as per 2007/01 FWH
           if ::bChange != nil .and. ( ::oGet:Changed .or. ( ::oGet:buffer != nil .and. ::oGet:UnTransform() != ::oGet:Original ) )
//           if ::bChange != nil
              lAccept = Eval( ::bChange, nKey, nFlags, Self )
              if ValType( lAccept ) == "L" .and. lAccept
                 if Upper( ::oWnd:ClassName() ) == "TCOMBOBOX"
                    ::oWnd:oWnd:GoPrevCtrl( ::hWnd )
                 else
                    IF !::oWnd:GoNextCtrl( ::hWnd )
                      return Super:KeyChar( nKey, nFlags )
                    endif
                 endif
              endif
           else
              if Upper( ::oWnd:ClassName() ) == "TCOMBOBOX"

Alex,

Do you mean child windows instead of child dialogs ?

Posted: **Tue Jun 12, 2007 10:09 am**

No, child dialogs, as in

DEFINE DIALOG ::oDlg ;
OF ::oBrwMgr:oBrw ;
Color ::oBrwMgr:oBrw:nClrText, rgb(224,224,224) ;
FONT oApp():oFnt ;
PIXEL FROM anDim[1], anDim[2] TO anDim[1] + nHeight, anDim[2] + nWidth;
STYLE nor(WS_POPUP, WS_VISIBLE)

Alex,

Modal or Non modal ones ?

Posted: **Tue Jun 12, 2007 10:23 am**

Modal.

I'm busy building a line edit of custom controls on top of a browse with each control in a modal dialog. When the user presses up/down/tab/enter, etc in the control in the single control dialog, I need to catch it. That's why I made GoNextCtrl/GoPrevCtrl return a logical indicating focus was changed.
