QTableView and Large data sets

[KenJustKen]

I am in the process of rewritting an app that does the following. Pulls in tens of millions of 64 Byte records from a data acquisition card and then display the data in a table with about 4-6 columns. I will not need to sort the data, I just want to display the data. The previous owner was trying to just load the data into a QAbstractItemModel and then load this directly into a QTableView. However, as several posts here and other places point out that this is really really slow with this size of dataset. Some suggest using a "proxyModel or Custom Model" to only pull the part of the data set from the file into the QTableView using the location of the current scroll bar as the "index". Where can I find a good example of this or what would you suggest?
