Description
If SignalSpy signalName property is defined before target property we can see that SignalSpy count property returns doubled value.
See the only difference is order of target and signalName:
SignalSpy {
id: spySignalNameFirst
signalName: "antialiasingChanged"
target: rect
}
SignalSpy {
id: spyTargetFirst
target: rect
signalName: "antialiasingChanged"
}
value of rect is changed in initTestCase only once:
function initTestCase() {
rect.antialiasing = true;
console.log("spySignalNameFirst.count: " + spySignalNameFirst.count)
console.log("spyTargetFirst.count: " + spyTargetFirst.count)
}
And output shows that value is different depending of the property order:
QDEBUG : tst_testCase::myTest::initTestCase() qml: spySignalNameFirst.count: 2 QDEBUG : tst_testCase::myTest::initTestCase() qml: spyTargetFirst.count: 1
Test project for above test atached.
If signal from rect is attached more than once it cause spySignalNameFirst.count value to be always double of the spyTrgetFirst.count value.
