Questions tagged [qabstracttablemodel]

QAbstractTableModel is a class in Qt for models that represent their data as a two-dimentional array of items.

The QAbstractTableModel class can't be used directly, but one can subclass his own class from it to represent a specific Table Model. However, the interface of this class is more specialized than QAbstractItemModel, so your derived classes can't be used in tree views.

A list of functions that need to be implemented when subclassing QAbstractTableModel includes:

  • rowCount()
  • columnCount()
  • data()
  • headerData()
  • setData()1
  • flags()1
  • insertRows()2
  • removeRows()2
  • insertColumns()2
  • removeColumns()2

1: for models that support editing.

2: for models with resizable data structure.

Official documentation is available here.
