Trigger loading a list of files from Dolphin using "open with"

[J Blackquill]

Hi, this is controlled by the KIO::ApplicationLauncherJob.
It asks KService whether it can launch one instance or if it needs to
do n instances, and this is the code that KService uses for that:

bool KService::allowMultipleFiles() const
{
   Q_D(const KService);
   // Can we pass multiple files on the command line or do we have to
start the application for every single file ?
   return (d->m_strExec.contains(QLatin1String("%F")) //
           || d->m_strExec.contains(QLatin1String("%U")) //
           || d->m_strExec.contains(QLatin1String("%N")) //
           || d->m_strExec.contains(QLatin1String("%D")));
}

In short, you should be using the standard XDG thing that says you can
take multiple URLs on launch in your .desktop file (%U in the Exec
key).

Cheers, Janet
