>> alternately, if "loading only what you see" is just "how it's done", then can i just set the scroll bar height to be the total height?  so CAN still grab the scroll thumb, and drag it to the end, and see the data at the end, without waiting for all the unseen data to load?

QTableView with QSortFilterProxyModel

when showing the view for the proxy model:

while (modelP->canFetchMore(modelIndex)) {

	if (dlgP) {

but that is way slow

i'd rather just quick-calc the number of items and set the scroll bar to max at the start
then let the viewer fetch what it needs to when the rows get revealed?

is this possible?

or can i pre-load the proxyModel at startup and just "swap it in" when the user switches playlists?
