[FIXED] Capture signal parameter in qml

Issue

I have a QObject based python class as follows:

from PyQt5.QtCore import QObject, pyqtSlot, pyqtProperty, pyqtSignal

class Validator(QObject):
    authFailed = pyqtSignal(str, arguments=['value'])

    def __init__(self, parent=None):
        super(Validator, self).__init__(parent)

    @pyqtslot
    def test(self):
        self.authFailed.emit("Failed")

On the qml side, I can listen to this signal as:

Validator {
    onAuthFailed: {                
    }   

    id: validator
}

However, I am not sure how I can capture the strparameter that is also emitted from the signal (The Failed message). When I try something like: onAuthFailed(msg) signature, this fails to compile.

Solution

I don't know about PyQt...

Usually, in QML you can access the signal parameters just by using their name.

According to this: http://pyqt.sourceforge.net/Docs/PyQt5/signals_slots.html#PyQt5.QtCore.pyqtSignal

the String you pass in the arguments=['value']-list is the name, that is used to expose the parameter to QML. So I am pretty sure, you can just use a variable value in the handler in QML.

Try:

onAuthFailed: console.log('auth Failed: ', value)
