No I won't be doing that. I really want to eliminate global variables from
the library.
However, I've already come to your aid because getHandle() can now get a TV
Item's handle.
tvih = getHandle( {TV, index} )

Euman,
I've completed your demo to enable it to save the text okay. I'm now
updating it to edit existing text. I have to go to a meeting now so I'll get
back later today with the update.

Look, if you think Win32lib is overkill for your system then use something
else and get over it.
I have consistantly said that Win32lib is not the fastest way of executing
Windows code. But it isn't trying to be. I hope that people find it easier
than raw API to code with, that's all.

Firstly, you don't *HAVE TO* subclass the edit control if you don't want to.
That is your choice. Windows doesn't force you to.
Secondly, yes I do have a one word command for this.
I've just added this bit of code the library...
---------------------
global function subClassControl(object pId, atom phWnd)
integer lNewId
integer lParent
integer lControlType
if phWnd = 0 then
return 0
end if
if sequence(pId) then
lControlType = pId[1]
lParent = pId[2]
if getId(phWnd) != 0 or -- hWnd already has an ID
phWnd = getHandle(lParent) or -- is its own parent
lControlType < 1 or -- invalid control class
lControlType > NumClasses then
return 0
end if
lNewId = NewControl(lControlType, lParent)
else
lNewId = pId
end if
setId( phWnd, lNewId )
-- Set up data for child control
window_handle[lNewId] = phWnd
window_handle_type[lNewId] = kht_Window
window_func[lNewId] = w32Func( xSetWindowLong, { phWnd, GWL_WndProc,
SubProcAddress } )
return lNewId
end function
----------------
and with this one can write ...
tvEditor = subClassControl( {EditText, myWindow}, tvhWnd)
and then all the win32lib functionality comes into existance for this new
control.
Also, to make live a bit easier than having to make global the library's
varaibles, you can replace the existing routine "getId" with...
global function getId( object hWnd )
if sequence(hWnd) then
return find( hWnd[2], tvitem_handle )
else
return w32Func( xGetWindowLong, { hWnd, GWL_USERDATA } )
end if
end function
and now you can get a TV Item's ID if you know its handle.
TVI = getId ( {hWndTVI} )
---------------
Now with these small mods to the library, here is your example reworked...
