Hm.
How would the dialogs know when to ask, then? How would the table dialog
know that the cursor moved to a different table column, a different table,
or completely out of any table?
The kernel need to tell somehow. We can't have every dialog polling for
changes, a horrible overhead.
This is how it's done actually: after each action updateToolbar() will
update all buttons and all visible dialogs. Not that much of an overhead.
A simple signal that cause every open
dialog to check for changes also has overhead - usually only a few
dialogs/toolbars change if any.
Telling the dialog(s) in question (via a function call) seems reasonable
enough.
If you want to make it very generic, consider having the dialogs
registering
callbacks with the kernel. Efficient, but lots of work achieving little
more
than simple function calls. :-/
There's some misunderstanding here. I am saying that no inset should
know anything about which dialog it is attached to.
Let's postpone this discussion to later, I don't have much time right
now, sorry.
