Question

I’m trying to emit a signal and send two parameters, one is a list of Song objects, and the second is a QtGui.QTableView object.

I tried doing that:

self.emit(QtCore.SIGNAL("searchOutput(list, QtGui.QTableView)"), songsObjs, self.table)

But I get the following error:

TypeError: C++ type 'list' is not supported as a slot argument type

What can I do?

Answer 1

If you have a look at the reference then it says

It is possible to pass any Python object as a signal argument by specifying PyQt_PyObject as the type of the argument in the signature.

and

While this would normally be used for passing objects like lists and dictionaries as signal arguments, it can be used for any Python type.

So try instead to do this:

self.emit(QtCore.SIGNAL("searchOutput(PyQt_PyObject, QtGui.QTableView)"), songsObjs, self.table)
