[Qt-qml] QML GridView vertical scroll behaviour

[Marcos Santamaria]

Hi

I am working on a QML GridView, which contains 7 items per row and 2 visible
rows at time. And with a total of 40 items.
It is populated with a model obtained from C++ ( QAbstractListIModel
subclass ) on a STB ( set top box device ).

When I try to scroll the GridView it has a rare behaviour.
Well, it begins moving the focus and freezing for a while. Then it allocates
some delegates components on memory ( console output traces ) and finishes
moving the focus to the new item.

The above always happens when the GridView scrolls a row

I have unsuccessfully tried some alternatives like the "cacheBuffer"
property, QML plain simple dummy models, simple delegates, ...

What can I do to solve or optimize this behaviour? Maybe something related
to Flickable? Animation States?

Thanks in advance,

Regards,
Marcos Santamaria
