[KCompletion] Port away from deprecated methods in Qt 5.14

Authored by dfaure on Tue, Sep 10, 5:42 PM.



the QComboBox::activated(QString) signal being deprecated
and optionally non-existent makes this interesting in subclasses trying
to emit it.

Test Plan

-DQT_DISABLE_DEPRECATED_BEFORE=0x060000, make, ctest
and playing a bit with kcompletionuitest.

With this removed, the KUrlComboBox in e.g. "Look in" in KFind autocompletes history entries rather than paths when hitting tab.

Good catch!

More precisely, history entries are offered in the lineedit edit, pre-selected, and only hitting "Del" allows to get normal path completion.

Amazing. setAutoCompletion(false) really only does setCompleter(nullptr) like we do (and setting the bool for the old unused property).

Ah.... unless we're not yet editable when coming here, and we're made editable later, then no code is doing the setCompleter(nullptr) anymore. Tricky!

In fact, due to the way init() is called, isEditable() is *NEVER* true here.

I'll keep working on a fix, just wanted to let you know I'm on it.
