</span>Yes, .desktop files.<br>
<br>
Since you're patching Qt anyway for Macports (it seems), you should probably<br>
change ApplicationsLocation to remove /Applications and only keep<br>
/opt/local/share/applications in there.<br></blockquote><div><br></div><div>Yeah, that would work. I'd rather not have it remove /Applications, but it could certainly add /opt/local/share/applications to it's list of ApplicationsLocation locations. I'm a bit conflicted on the QSP issue currently. I can see as Rene pointed out it may be good to give all unixy paths when configured with a different flag at build time, but what if I created an application that used some kde frameworks but wanted it to give me OSX type paths for some things?</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</span>Patch looks good, you can commit it.<br></blockquote><div><br></div><div>Ok, I will, I'll give it more thought, but I wonder which parts of kded/kbuildsycoca make sense on non plasma platforms. Another question that might help clarify this, do Gnome/Unity, other linux desktop environments use the cache kbuildsycoca creates when building their menus or is it strictly used by plasma (or rather kickoff/kicker which is part of plasma) itself? </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</span>kded watches the same dirs, so that it can launch kbuildsycoca when a .desktop<br>
file is installed/removed/changed.<br>
<br>
kinit and klauncher are mostly separate from that. kinit is the "fork+exec to<br>
avoid relocations" mechanism (see kinit/README.md), and klauncher is the DBus<br>
API for it (kinit can't initialize DBus, since that would be inherited after<br>
forking).<br></blockquote><div><br></div><div>Ok, that does help explain what they are. Next is to know what uses them. Are they required for kparts to work, or for KService/KServiceTypeTrader to work? or is only kded required for those to function properly?</div><div><br></div><div>Thanks for the information, I do appreciate it.</div><div>Jeremy </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
