Pedro,

Aqui tienes un ejemplo completo:

Code: Select all

// Detecting the tap-and-hold event

#include "FWCE.ch"

#define SHRG_RETURNCMD     1
#define GN_CONTEXTMENU  1000

#define MF_ENABLED         0
#define TPM_VERTICAL  0x0040

function Main()

   local oWnd := TMyWindow():New()
   
   oWnd:SetText( "Tap & Hold" )
   
   ACTIVATE WINDOW oWnd ;
      ON CLICK CheckTapAndHold( oWnd, nRow, nCol )
      
return nil

CLASS TMyWindow FROM TWindow

   METHOD Command( nWParam, nLParam )

ENDCLASS

METHOD Command( nWParam, nLParam ) CLASS TMyWindow

   local nId

   if nHiWord( nWParam ) == 0 // MenuItem

      nId = nLoWord( nWParam )

      do case
         case nId == 10
              MsgInfo( "One" )
              
         case nId == 20
              MsgInfo( "Two" )
              
         case nId == 30
              MsgInfo( "Three" )
      endcase                
   endif   

return Super:Command( nWParam, nLParam )

function CheckTapAndHold( oWnd, nRow, nCol )

   local hMenu

   if SHRecognizeGesture( oWnd:hWnd, nCol, nRow, SHRG_RETURNCMD ) == GN_CONTEXTMENU
      // MsgInfo( "Tap & Hold" )
      hMenu = CreatePopupMenu()
      AppendMenu( hMenu, MF_ENABLED, 10, "One" )
      AppendMenu( hMenu, MF_ENABLED, 20, "Two" )
      AppendMenu( hMenu, MF_ENABLED, 30, "Three" )
      TrackPopupMenuEx( hMenu, TPM_VERTICAL, nRow, nCol, oWnd:hWnd )
   endif
