value in an array property of itself. It also has a Restore
method that restores the value of one or all saved
properties. The Restore method is also called from the
Destroy method, so when the _ObjectState object goes out
of scope, everything is restored automatically. Since the
array property has a single row for each saved property,
you can’t use this class to provide multiple levels of undo;
however, you could subclass _ObjectState and add this
behavior if desired.
Where might we use such a class? One situation
involves things a user can change but might want to
change back. For example, you might allow a user to
rearrange and resize the columns in a grid, but provide a
“Reset to Default” function that puts them back. Another
place would be when you temporarily change the
properties of an object (perhaps so it behaves differently),
do something with the object, and then change them back
again. Rather than having a set of local variables that save
the property values and then having to manually restore
them before the routine ends, you could do something
like this:
local loObjectState
loObjectState = newobject('_ObjectState', '_app.vcx', ;
'', This)
loObjectState.Set('
