Description
<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd"> <node> <interface name="sample.client"> <method name="dualOutputMethod"> <arg type="b" direction="out"/> <arg type="i" direction="out"/> </method> </interface> </node>
Here's a sample dbus xml with multiple output. This is handled just fine using DBUS_INTERFACES in the qt .pro file, but it isn't quite handled using DBUS_ADAPTORS (both undocumented...). I get output like this:
bool ClientAdaptor::dualOutputMethod(int &out1) { // handle method call sample.client.dualOutputMethod //return static_cast<YourObjectType *>(parent())->dualOutputMethod(out1); }
The solution I found online was to use the "-l" argument with qdbusxml2cpp, which would then mean I couldn't use DBUS_ADAPTORS anymore, and I'd have to implement some hack of using system calls in the header, or some other method of generating the cpp files. DBUS_ADAPTORS should be able to handle methods with multiple outputs, or someway to pass in the "-l" argument for that variable.
One other thing to note is that I originally had a custom abstract dbus adaptor which worked just fine with multiple outputs as a workaround to using this variable... In case more people stumble upon this issue and are looking for workarounds that work for them (http://doc.qt.io/qt-5/usingadaptors.html).
