[Kde-pim] KMail: "smart paste" of email addresses

[Kevin Krammer]

Hi all,

since a respective generic question on k-c-d got no reply for about a week 
now, I take it that it is no longer possible to intercept text going into a 
QLineEdit or its subclasses.

Since the AddresseeLineEdit in libkdepim used this (i.e. reimplementing 
KLineEdit::paste(), KLineEdit::insert()) to implement the so called "smart 
paste" feature, it no longer works.

From my somewhat limited investigation the only reasonable way to implement 
this now is to use a QValidator on the line edit and let it "fixup" the 
string.
However, since intercepting paste() doesn't work any longer either, it could 
only be turned on/off on middle-mouse-button pastes, it will probably have to 
work continuously, i.e. not just when inserting text through pasting.

Another option, though not totally equivalent in behavior, might be to 
implement this in the completion handler. Not totally equivalent because 
pasting doesn't seem to trigger completion by itself, but this might depend 
on the completion mode setting.

Any preferences which way I should investigate further, or maybe any other 
option I am overlooking?

Cheers,
Kevin
