Hi Renato,
Here's a complete example. I run the file containing this, and the only
message printed is the error I wrote about above; the method is never
called. If I use int in the test method, everything works fine.
--------------------------------------------------------------------------------------
from PySide import QtCore
from PySide.QtGui import QApplication
from PySide.QtScript import QScriptEngine, QScriptValue
app = QApplication([])
class Test(QtCore.QObject):
@QtCore.Slot(list)
def test(self, param):
print 'test method called, param is', type(param), param
engine = QScriptEngine()
test = Test()
test_qobject = engine.newQObject(test)
engine.globalObject().setProperty('test', test_qobject)
val = engine.evaluate("test.test([1, 2, 3])")
print val.toString()
