Scripting: static collection 2004-03-09 - By Bradley Gabe
Back
Some basics on OOP. You'll need to get a firm grip on the difference
between assigning pointers to objects, creating objects, running object
methods, and getting/setting object properties.
ch_coll = new ActiveXObject( "XSI.Collection" ); // Creates a new XSI
Collection obj pointed to by ch_coll.
ch_sel = selection ; // Points var ch_sel to already existing Selection object.
ch_coll = ch_sel ; // Points var ch_coll to same thing ch_sel is pointing to,
selection.
// What you've done is create an object, then lose it by reassigning its
pointer to something else.
ch_coll = new ActiveXObject("XSI.Collection"); // Create a new XSI
Collection obj
ch_coll.AddItems(selection); // Populate the new collection with items
from selection object.
// Once the AddItems() method is run, your ch_coll is set and won't do
anything until you add or remove items.
