Bug ID: 371515
Summary: Adding new entry is slow
Product: KBibTeX
Version: 0.6
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: User interface

Proposed fix
Especially with the biblatex style, adding a new entry to a database can be
extremely slow. It takes up to ~10 seconds until the widget edit dialog finally
pops up.
Debugging revealed that the culprit is FileView::setSelectedElement, more
precisely the loop over all columns added in
https://quickgit.kde.org/?p=kbibtex.git&a=commit&h=4f529a8444e4c
In my case, this loops over all (130!) columns just for the sake of selecting
the whole row after the new entry has been added.
I'll attach a patch which uses the QItemSelectionModel::Rows flag instead,
which has the same effect but is _much_ faster (the editing window now pops up
almost instantaneously).
