不支持C++類型的slot參數

Question

我試圖發出一個信號併發送兩個參數，一個是Song對象列表，第二個是QtGui.QTableView對象。

我試着這樣做：

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

，但我得到了以下錯誤：

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

我能做些什麼？

Answer 1

如果你看看reference然後它說

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.

所以會轉而做：

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