Hello again Derek,

Could you change this in Win32lib?

make [window_handle] a global sequence

-- controls
global sequence
    window_handle              -- hwnd of controls

sequence
    window_handle_type,         -- Type of handle
    window_destroyed,           -- true if destroyed
    --etc...etc

Derek replies....
 Absolutely NOT! This is against good programming practices as it opens up
the library to changes that it cannot control. If you need access to the
values in this fields, you can ALREADY do that by calling the
getControlInfo() routine.

       lValues = getControlInfo(myWin,
                      {CONTROLINFO_handle,
                       CONTROLINFO_handle_type,
                       CONTROLINFO_destroyed
                      })
will return a sequence containing the three requested values.

However, if you just want the handle info you can use the (undocumented)
getHWND(id) function. Or the function getHandles() to get every handle that
win32lib has.

I will not expose anymore variables as global - there are too many already
exposed.

Derek.
