I guess "easy" depends on how much one knows KFileWidget :) Especially
all the connections between the widgets and double vs. single click mode
make it not so easy to emit the right signals in all cases. 

I could solve my problem without a new signal, but it would've helped my
use-case if there were a signal thats emitted whenever the "current url"
changed, i.e. by editing the line-edit, by choosing something from
places, by entering/leaving a dir in the dir-op, by using the toolbar or
when selecting a file in the dir-op. I thought fileHighlighted would do
the job for me, but thats only emitted when clicking a file in the
dir-op.

Just in case you're curious: I'm embedding KFileWidget into a wizard
which allows to select various types of files or dirs and I need to
update the wizards state based on the selected file/directory. The
selection from KFileWidget dictates wether there's another page and the
page is valid at all. So I just need a notification whenever the user
navigates to some place in the KFileWidget.
