[Qt4-preview-feedback] Qt4-preview-feedback Digest, Vol 10, Issue 47

[ronan.maclaverty at nokia.com]

Hi all.

There is a bug in the qdbusxml2cpp compiler: it does not handle signals correctly (IMHO).

The issue is that signal "out" arguments are treated as "in" arguments, meaning that objects and structs are passed as bit-copies not references - this is particularly annoying if using user defined types.

Please, correct me if I am wrong.

The fix to the compiler (qbusxml2cpp.cpp - Qt-4.5.0-rc1) would be:

730            QStringList argNames = makeArgNames(signal.outputArgs);
731            writeArgList(hs, argNames, signal.annotations, QDBusIntrospection::Arguments(), signal.outputArgs);

And

1073            QStringList argNames = makeArgNames(signal.outputArgs);
1074            writeArgList(hs, argNames, signal.annotations, QDBusIntrospection::Arguments(), signal.outputArgs);

Regards

Ronan.
