Hi!

I was just trying to find out why Ctrl-N (new tab) clears the location bar=
=20
twice.  This annoys me a lot, since I always start typing=20
e.g. "<Ctrl-N>gg:konqueror rules", but end up with "ror rules" in the=20
location bar (especially in high-load situations).  I found out that the=20
guilty KonqMainWindow::slotPartActivated() gets called twice when opening a=
=20
new tab (both calls via KonqViewManager::emitActivePartChanged()), which=20
looks like a bug AFAICS.

The reason is that KonqViewManager::showTab()
1) first calls showPage(), which leads to a call of setActivePart() that=20
starts m_activePartChangedTimer, and then
2) directly calls emitActivePartChanged().
3) Then the timer from 1) fires and emitActivePartChanged() is called again.

What I did not yet find out is why showPage() leads to a call of=20
setActivePart() (although that does not sound wrong in any way).  Now maybe=
=20
someone with more knowledge of Konquerors internals could comment on this=20
(and the above)?

Ciao, /  /                                                    .o.
     /--/                                                     ..o
    /  / ANS                                                  ooo
