c++ - How to determine when at the bottom / end of a QListView? -

i'm using qlistview wraps simple list model. try implementing similar "infinite scroll" seen in web pages.

currently model updated method adds @ 100 items (they're taken external web api takes @ 100 items per call). goal: when user moves last element of list view (in case, scrolling down) start call 100 more items, , on.

to simplify in example:

1. populate list 100 items
2. view scrolled down (by user) bottom
3. other 100 items fetched.

is there in qlistview tells me when i'm @ end of visible view?

qlistview subclass of qabstractscrollarea, 1 way of finding out if vertical scroll bar's position @ 1 of extremes to:

1. get qscrollbar object used qlistview calling verticalscrollbar().
2. connect slidermoved(int value) signal of scroll bar slot of choice.
3. in slot, fetch min/max values of scroll bar , compare them value given in signal.
