[Okular-devel] handle 'point and click' events (textedit-URIs)

Hi,

thanks for pointing out the issue, and for using Okular of course :)

Luckly we have some days before KDE 4.2, so the we can find a solution.

I personally find the idea of using a envvar quite "raw" and not that much 
user friendly (aren't we both developing nice comfortable GUIs for our 
users? ;) ).

Okular in KDE 4.2 provides a way to configure the editor to be launched 
for "sources", ie when working with DVI files with inverse search hyperlinks.
Using this configuration, the user can also setup Okular for DVI integration 
within Kile. The interaction way used for Kile is to run it telling it to go 
at a specified line of a source file (something like `kile --line 10 
thefile.dvi`).
IMHO, this way could also be applied for Frescobaldi. Although, from what I 
see from the Frescobaldi' sources, it allows multiple instances of it, unlike 
Kile. A second problem (that could be solved with an hidden configuration, at 
least for KDE 4.2) is that it should be possible to configure the editor for 
different file types (eg "frescobaldi --line %l %f" for 
application/x-lilypond, "kile ..." for "application/dvi", etc).
This would have the advantage that the user could just configure the editor 
for lilypond files once, and forget about it :)

What do you think?
