<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">New stuff to learn/discover: one can also connect signals with each other, thus no need to go via a slot, just to emit another signal. So all these three slots might not be needed, instead you can just three times do like this:
connect(menu, SIGNAL(addTagToResource(KoResource*,QString)),
this, SIGNAL(addTagToResource(KoResource*,QString)));
See http://qt-project.org/doc/qt-4.8/qobject.html#connect, grep for "A signal can also be connected to another signal"</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">That's a pretty cool thing to know 8) and I think I can use this knowledge to reduce some needless relaying in the resource server adapter.
Does it really apply to this particular case, though? Since the SLOT KoResourceItemChooser::contextAddTagToResource(KoResource*,QString) isn't just a relay (at least not completely), it's the actual final destination.
It does also trigger the synchronization of all the resource item choosers of the same resource type, though. </pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Well, it's done this way because the first (zero) index of the TagBox is the Unfiltered/All Presets view and thus isn't really a tag, but at this point, getting combo box items is the only way to have empty tags open for assignment for the context menu. Querying the tag object directly wouldn't return these empty tags since the tag object only tracks tags with content.
I see the confusion though, and adding an extra list to track tags instead of querying the combo box was one of my first ideas, but I didn't go through with it since the current approach was quicker (plus I wanted (and still will ;) ) to refactor all that TagBox stuff out into its own widget, which would have done this properly), but it's rightfully biting my behind now ;). I'll fix it.</pre>
