Hi Andrew--
Sure, you can do this. Use the "modify_tag" doc callback to fix up the attribute value list, something like this:
function mt_callback(doc, oid, win, op) {
if (op == 1) { return 0; }
# get doc ID
local dlgdoc = _xmldlg::getDialogDocument(win);
local tagname = oid_name(oid);
# get list of attrs with enumerated values (comboboxes in modify attrs dlg)
local attrs[], a;
oid_xpath_nodeset(oid_root(dlgdoc),attrs,"//combobox");
# find the attr we want to modify
local values[], v, alias, attr;
for (a in attrs) {
attr = attrs[a];
attrname = oid_attr(attr,"id");
if (//attrname is attribute to be modified//) {
# hide unwanted values
local items[], i;
oid_find_children(attr, items, "listitem");
for (i in items) {
local label = oid_attr(items[i],"label");
if (//label should be removed//) {
oid_delete(items[i]);
}
}
}
}
}
Then, somewhere in your initialization code, make sure you add the callback:
doc_add_callback(0, "modify_tag", "mt_callback");
Replace the bits between double slashes //..// with proper tests and this will give you better control of the attribute values without having to modify the schema.
