Dear Jimmy,

In you Class TGrid please implement this method:

METHOD GetHotPos() VIRTUAL

[Jimmy]

hi Antonio,

METHOD GetHotPos() VIRTUAL

i have try to include

Code: Select all  Expand view

METHOD GetHotPos() VIRTUAL

in my CLASS TGrid() and CLASS TExplorer() but still get Error ...

---

after disable and reduce used CLASS i got to TControl:HandleEvent() which are SUPER CLASS of TGrid()

i have look for

Code: Select all  Expand view

METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TControl
...
1834       case nMsg == WM_SYSCOMMAND
1836           return ::SysCommand( nWParam, nLoWord( nLParam ), nHiWord( nLParam ) )

so i "override" it in my CLASS TGrid()

Code: Select all  Expand view

METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TGrid
   DO CASE
      ...
      CASE nMsg == WM_SYSCOMMAND
         RETURN nil
   ENDCASE

now i got no Error any more

later when want to use ALT as Hotkey in TGrid() i can change it
thx for help to point me Direction to go

very good
