TControl is derived from TWindow.
You need to search both TControl and TWindow classes.

You can see from TWindow class
Code: Select all  Expand view
METHOD RButtonDown( nRow, nCol, nKeyFlags ) CLASS TWindow

   if ::bRClicked != nil
      Eval( ::bRClicked, nRow, nCol, nKeyFlags, Self )
   endif

return nil

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

METHOD RButtonUp( nRow, nCol, nKeyFlags ) CLASS TWindow

   if ::bRButtonUp != nil
      Eval( ::bRButtonUp, nRow, nCol, nKeyFlags, Self )
   endif

return nil

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


That means, you need to add method

Code: Select all  Expand view
METHOD RButtonDown( nRow, nCol, nKeyFlags ) CLASS YourClass

hi,

thx for Answer.

i´m not sure that i understand what you say

i do have use

Code: Select all  Expand view
METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TGrid  

   DO CASE
      //  use for LVS_OWNERDRAWFIXED
      CASE nMsg == WM_MEASUREITEM
      CASE nMsg == WM_DRAWITEM
      // add for Context Menu
      CASE nMsg == WM_RBUTTONDOWN
         IF ::bRbClick != nil
            EVAL( ::bRbClick, ::oWnd, Self )
         ENDIF
      CASE nMsg == WM_RBUTTONUP
   ENDCASE

RETURN ::Super:HandleEvent( nMsg, nWParam, nLParam )


now you say i "just" need to "override"
Code: Select all  Expand view
METHOD RButtonDown  ( nRow, nCol, nKeyFlags   )   CLASS YourClass

so i need not to handle WM_RBUTTONDOWN :?:

Yes.

Wherever the parents have standard methods, you override them in your class and if needed return calling Super method.
Use HandleEvent very sparingly when there is no otherway.
