Hi! I’m experiencing a problem that might be a bug in PyQt. I've made
a code example that demonstrates the problem:
class CommClient(QObject):
def __init__(self, parent=None):
QObject.__init__(self)
self._devicelist = ""
self.timer = QTimer()
self.timer.timeout.connect(self.test)
self.timer.start(2000)
def setDeviceList( self, devlist ):
self._devicelist = devlist
self.deviceListUpdated.emit()
def getDevicelist(self):
return self._devicelist
deviceListUpdated = pyqtSignal()
devicelist = pyqtProperty(str, getDevicelist, notify=deviceListUpdated)
def test(self):
self._devicelist = "YES"
self.deviceListUpdated.emit()
self.timer.stop()
app = QApplication(sys.argv)
qmlRegisterType(CommClient, 'SDL', 1, 0, 'CommClient')
view = QQuickView()
view.setWidth(500)
view.setHeight(500)
view.setTitle('CommClient')
view.setSource(QUrl('main.qml'))
view.show()
app.exec_()
And the QML file:
import QtQuick 2.0
import SDL 1.0
Rectangle {
width: 400
height: 400
Text {
id: myText
text: commClient.devicelist
anchors.horizontalCenter: parent.horizontalCenter
}
CommClient {
id: commClient
}
}
When the timer fires and the signal is emitted I get:
ASSERT failure in QVector<T>::at: "index out of range", file
../../include/QtCore/../../src/corelib/tools/qvector.h, line 350
I'm running the latest snapshot of PyQt5.1 (
PyQt-gpl-5.1.1-snapshot-41b8f6ca2ea4. ) and stable Qt5.1.1 built from
source on Ubuntu 12.04.
