how can I get my "listview" container's items be displayed in a recycleview fashion? #379

As stated, I'm thinking if how to get my listview containers items to be displayed in a recycleview fashion.

My program runs fine when I don't have too many objects in my containers Include.objects list but when it gets crowded the program crashes.

Would I have to use a rawwidget to use a qlistview object? (Which seemingly would support the recycle approach)

Could you clarify what you mean by recycle approach ? Also could you post the traceback of the crash and a minimal reproduction example.

I am thinking of a view like kiwi's Recycleview, which uses a memory efficient approach to display the child widgets.

Or is this already the case in enaml?

When I have a lot of the listitems in the container mentioned here the program runs until I scroll rapidly through the list, then crashes. It only happens when the list is large.

No it is not the case in enaml. First, because it does not make sense in an Include that can receive arbitrary widgets. It could be interesting in a Looper but I am not sure how we would do that without tying it to the backend.

Thanks for the reply! Do you suggest wrapping a QListWidget via a RawWidget? My "ListItems" would have to be QListItems then , am I seeing this correctly?
