[Kde-hardware-devel] Solid - how to get path of storage device

[David Boosalis]

Hi Chris.

The signal gets generated from a USB being plugged in.  I use the following
to connect the signal to the slog given:

  connect(DeviceNotifier::instance(),
      SIGNAL(deviceAdded(const QString &)),
      this,
      SLOT(slotSolidDeviceChanged(const QString &)));

  connect(Solid::DeviceNotifier::instance(),
      SIGNAL(deviceRemoved(const QString &)),
      this,
      SLOT(slotSolidDeviceChanged(const QString &)));

This was taken from the solid tutorial. Maybe I am getting an extraneous
signal when I plug in the usb stick because the qDebug statement for
filePath below prints nothing for hte filePath argument. I am using hte
latest build of the depot for all my coding work.  You mentioned something
about StorgeAccess::setup(), I'll research this call, as I am not sure where
to put it.

Thanks for the reply,
David


PS I am CCing the  hardware list by the way, but was unable to find the line
to subscribe to this group.
