But I think we want something more. I was thinking recently about this
exact issue, and I was wondering if we could use the same mechanism as the
menu code itself will use. I was considering building up every menu from a
set of signals (I think JMarc mentioned this), something like :
addMenu(menuid, name, shortcut);
addToMenu(parentmenu, itemid, name, shortcut);
removeFromMenu(parentmenu, itemid, name, shortcut);
attachMenu(parentmenu, itemid, menuid);
itemChanged(parentmenu, itemid, newname, newshortcut);
disableItem(), enableItem() etc.
or something (I haven't really thought this through). Actually Menu is
probably a bad name, we want to change TOC/ref dialog from these signals
as well. It would be especially convenient for Qt if "itemid" was globally
unique integer >= 2 (or <= -2).
This way we can have piecewise updates of TOC / Ref menus in a consistent
framework (anyone who cares can listen in).
TOC is a little unclear, though it's been discussed (though I had an idle
thought that perhaps the FinishUndo() calls would be a superset of places
we need to send signals ? I don't know).
I can even see TOC signals delivering the parent section of a subsection's
itemid (makes the dialog easier on Qt for heirarchical purposes).
Note that for lyxaction entries, the menuid could jsut be the action
number. For other things like the Documents submenu, we could reserve a
space in the action number lists for the dynamic stuff.
Basically what I'm saying is, I'm not sure ad-hoc updating methods would
necessarily be a good idea until a sensible framework is in place. What do
people think ?
thanks

p.s. dynamic creation of menus sucks - luckily it can't work for tear-off
menus, so we *have* to have an update scheme. I would just rather see a
finer-grain system.
