Anyone? So the get-Me-Item function returns any QObject derivates.

Hi,
can you be a bit more specific?
I've tried it as:
var someItem = getMeItem()
connectionsElement.target = someItem
someItem.destroy()
With helper functions/QML:
function getMeItem() {
// dummy
return Qt.createQmlObject('import QtQuick 2.0; Rectangle {
Component.onDestruction: console.log(\"XXX ~Rectangle. this I cannot access")
}', root)
}
Connections {
id: connectionsElement
target: null
Component.onDestruction: someItemDeleted()
}
function someItemDeleted() {
console.log("XXX someItem deleted. This I want get called ")
}
The ~Rectangle gets called but not someItemDeleted function.
-P

Hi,
Try connecting to the "Component.onDestruction" signal.
Cheers,

Hi,
How do I know when item is deleted (destructor called) in QML/JavaScript?
I tried:
Connections {
target: someItem
onDestroyed: console.log("someItem deleted") } ==> results: QML
Connections: Cannot assign to non-existing property "onDestroyed"
And in JavaScript:
someItem.destroyed.connect(loggingItem, someItemDeletedFunction) ==> results:
TypeError: Cannot call method ´connect´of undefined.
Reading the documentation and the code (5.0), the QObject has signal
destroyed(). The someItem is defined in cpp and it's registed to QML (otherwise
it works fine). Replacing the code snippets with any other signal works fine.
Any ideas?
Thanks,

P.s I do not control the construction of the item so I cannot override the
Component.onCompleted: in the element definition.
