QML ListView atYEnd not emitted

[teh_raab]

Hi All,

Im using QtCreator and have written a basic QML test app to demonstrate an issue i've been seeing..

Scenario:-
ListView component with more delegates than can fit in to the view. Delegates (for this demo) consist of a green rectangle with a blue border. There is a red rectangle which we append to the end of this listview to indicate that there are more items below. This red rectangles visible property is bound to the list views atYEnd. So when we are at the very bottom of the list view, the red rectangle should be hidden; otherwise, we display it.

Issue:-
Flick (not drag) to the end of the listview and the red rectangle will still be visible. It seems the atYEnd is not emitted. If you were to then take note of the bottom delegates position and select and drag up, you'll notice that the delegate hasn't moved, yet the red rectangle has disappeared; meaning the atYEnd has been received.

Has anyone come across this issue before and if so, did you find a work around to correctly detect the end of the list view?

Thanks in advance,

Rob.

Just to update for anyone else that maybe seeing this issue. Upon further investigation, it appears that the issue is limited to QtQuick 1. Updating to QtQuick 2.x resolves this issue (although im stuck having to use QtQuick 1.1 for the time being :().
