[Qt-qml] QML Questions

[Jason H]

I'm putting this out on the list so others can refer to it...

Ah, I see, as the model loads stuff async, it adjusts content height 
continuously. I could very well use count, but I don't know the number of pixels 
per item. 


I really think the solution is some how to have the model inform the view it is 
ready and to start the animation.  How can I do that?

This is because the duration binds to contentHeight:

Whenever the contentHeight changes, the duration is reset. 

I suggest binding to something that doesn't change so much, like 
ListView::count.
