Hi Dave,
Most libs use functions to return a value to the calling program, =
since they can't directly put a value to the program variables.
IE. David Cuny's winlib..
when you create a control( a window or listbox or whatever), it =
returns a handle so you can access the control you created later.
example..
<CODE>
include win32lib.ew
constant
=
,0),
-- ^^ this is a function. it returns a handle so winlib =
can manipulate it in later code
Mnu_File=3Dcreate(Menu,"&File", Win_Main,0,1,0,0,0),
-- ^^ the value returned by create..... ^^ this is the handle return =
by creating the window
Mnu_Fexit=3Dcreate(MenuItem,"E&xit",Mnu_File,0,0,0,0,0)
-------------------------------------------------------------------------=
-----
--EVENTS
procedure onMnu_Fexit()
closeWindow(Win_Main)
end procedure
-------------------------------------------------------------------------=
-----
--EVENTS
onClick [Mnu_Fexit] =3D routine_id("onMnu_Fexit")
-- ^^ this is a function too..
WinMain(Win_Main, Normal)
</CODE>
