[SOLVED] Qt DBus signal not arriving
-
We are using a DBus interface (QDBusAbstractInterface) with this signal:
@ <signal name="ContentUpdated">
<doc>
<line>ContentUpdated = This signal updates the input content data for the specified session</line>
</doc>
<arg name="locationInputHandle" type="y" direction="out" />
<arg name="guidable" type="b" direction="out" />
<arg name="availableSelectionCriteria" type="aq" direction="out" />
<arg name="address" type="a{qv}" direction="out" />
</signal>
@Using qdbusxml2cpp it is translated to this interface:
@Q_SIGNALS:
void sgnContentUpdated(quint8 locationInputHandle, bool guidable, TUshortList availableSelectionCriteria, TUshortVariantMap address);
@For some reason, when i use the TUShortVariantMap in a QVariant::setValue() call the signal does not arrive anymore.
Below is the code where i do this. So without this code, and in particular the call to QVariant::setValue(), the ContentUpdates signal arrives without problems.@
void CGuidanceHandler::updateAdr(const quint32 aCurrentRouteOffset, const CRoadBookItem& aCurrentInstruction)
{
TUshortVariantMap valueOnRoute;
QDBusVariant offsetValue;
offsetValue.setVariant(QVariant(aCurrentRouteOffset));
valueOnRoute.insert(GENIVI_MAPDATAACCESS_OFFSET, offsetValue);QDBusVariant value;
QVariant innerValue;
innerValue.setValue(valueOnRoute); // This call results in the signal not arriving anymore
value.setVariant(innerValue);// etc..
}
@Any ideas why this can cause the signal not arriving anymore?
Or any other pointers why signals could not be arriving?
