Qt DBus: Byte type in QVariant, QVariantMap?

[minski]

Hi, i am trying to implement the following DBus interface using Qt:

void RegisterEndpoint(object endpoint, dict properties)
possible properties:

string UUID
byte Codec
array{byte} Capabilities

This is currently described in XML the following way:

    <method name="RegisterEndpoint">
      <arg name="endpoint" type="o" direction="in"/>
      <arg name="properties" type="a{sv}" direction="in"/>
      <annotation name="org.qtproject.QtDBus.QtTypeName.In1" value="QVariantMap"/>
    </method>

But when i call this method, i get an invalid arguments error.
I guess, the reason is, because QVariant cannot take a Byte type (converting to int instead):

properties	<3 items>	QVariantMap &
	[0] "Capabilities"	"À\020\204\200ÿÿ"	
		key	"Capabilities"	QString
		value	"À\020\204\200ÿÿ"	QVariant (QByteArray)
	[1] "Codec"	2	
		key	"Codec"	QString
		value	2	QVariant (int)
	[2] "UUID"	"0000110b-0000-1000-8000-00805f9b34fb"	
		key	"UUID"	QString
		value	"0000110b-0000-1000-8000-00805f9b34fb"	QVariant (QString)

Can anyone help out with suggestions to realize this?

Many thanks in advance!

Solved: you have to create a QVariant like this:
QVariant::fromValue(uchar(0)) -- instead of QVariant var = uchar(0);
