I have C++ class emitting signal and QML slot. I need to execute slot in the same thread after program returns to the event loop.
How can I achieve something like this?

@Connections {
target: box2dCppEngine
onBulletCollided: box2dCppEngine.deleteObject(bullet)
connectionType: Qt.QueuedConnection
}
@

I need this because I can not execute deleteObject, while processing the collision, I need to do this after world step.

Maybe you could make deleteObject() itself use deleteLater() ?

Maybe, but this forces me to make all my objects derived from QObject, which I don't like.

bq. Maybe, but this forces me to make all my objects derived from QObject, which I don’t like.

Why don't you like it? Any particular reasons? QObjects are pretty ubiquitous. :-)

Or make box2dCppEngine.deleteObject() add the object to a list and trigger a 0-timer to delete the objects in the list.
