Hello,
I’ve done some reading and can’t find anything on non-contiguous selection of items in item views beyond : “Selections are made up of *selection ranges*. These efficiently maintain information about large selections of items by recording only the starting and ending model indexes for each range of selected items. Non-contiguous selections of items are constructed by using more than one selection range to describe the selection.” - http://doc.trolltech.com/4.6/model-view-selection.html#concepts Currently we have implemented a selection of items by scanning each row in the model to see if it should be “selected” based on certain criteria. Is there a faster way to do this as looping in Python through a large (50,000 rows)? When selections can be specified with selection ranges the selection is fast. However, our worst case scenario is that every-other item need be selected: 25,000 selection ranges would be created and then we would just be looping through everything again anyways. Any ideas? Thanks, Darryl
