------- Comment #32 from wstephenson@xxxxxxxxxx 2006-11-13 10:31 MST -------
QString libhal_device_get_property_QString(LibHalContext *ctx, const char* udi,
const char *key)
if (udi == 0 || !strlen(udi))
return QString();
Danny: As you can see, we do check for a null returned from
libhal_device_get_property_string, but it still crashes unless we check for the
existence of the property first. I could put that check into
libhal_device_get_property_QString() but this causes another dbus roundtrip,
right? If I can do the lightweight check ( 1. in #26 ) I would prefer this.

Is your second suggestion actually the only way to do this safely, or is the
assert in dbus when getting unknown properties really that aggressive?

char* _ppt_string;
QString _ppt_QString;
DBusError error;
_ppt_string = libhal_device_get_property_string(ctx, udi, key, &error);
if (_ppt_string)
_ppt_QString = _ppt_string;
return _ppt_QString;
