[Qt-qml] Simulating QML which needs a long time to load

[Jerzy Chalupski]

I'm writing an application with several "views", which should be
loaded dynamically from separate QML files. I already have some basic
code which utilizes QML Loader element, and right now I'm thinking
about some "please wait" screen that would be displayed to user when
requested view takes a long time to load. But to test such code I need
a QML component which will emit completed signal after a long time.
What would be a simplest way to do this?
