Generally CuteReport consists of two parts: core library and template designer. Although C++ does not support garbage collection, automatic memory management of C++ objects can be achieved in a number of ways, primarily through the use of smart pointers and reference counting. For example, as shown in the diagram, we append three columns to a collection of six existing columns (ending in column 5), so first is 6 and last is 8: beginInsertColumns(parent, 6, 8); This appends the two new columns as columns 6, 7, and 8. We're using a custom subclass of QAbstractTableModel as the model for the QTableView. QListView or a PySide. Model/view also makes it easier to use more than one view of the same data because one model can be passed on to many views. If you need a model to use with a PySide.

On the other hand the check will disappear in a release build, so that we don't pay the price of the check at each invocation of data(). But it seems not a good way. More specialized usecases often require us to write our own model, for example in the next chapter we'll be implementing our own Table model by subclassing QAbstractTableModel (which itself inherits QAbstractItemModel). The documentation is a bit opaque, I prefer to see it working first, then figure out how it works. My code is looking something like this#include#include/***Model for storing data.
