embedded vim editor in KDE

[Yoram Hekma]

Ok, I posted before, but after reading my post, I see it was 
incomprehensible at best.

The problem is this:
I am using KDEVELOP, and I would like to use the vi-functionality that 
the kpart module is supposed to give me.
Now I configured the KDE Components in the system settings to use vim, 
and when I click "test" everything seems ok. However, I cannot select 
the embedded vim editor in KDEVELOP or in any other KDE app for that matter.

What am I doing wrong?
