不支持C++类型的slot参数

Question

我试图发出一个信号并发送两个参数，一个是Song对象列表，第二个是QtGui.QTableView对象。

我试着这样做：

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

，但我得到了以下错误：

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

我能做些什么？

Answer 1

如果你看看reference然后它说

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.

和

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

所以会转而做：

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