An adapter to create a vtkTable from an QAbstractItemModel.
An internal table is used to buffer the QAbstractItemModel. Any changes in the model are applied to the internal table, so that it is always up-to-date with the model.
Due to the structure of vtkTable it is not possible to have columns with different variable types. The variable type of a column is determined from the first row in the model.
The data is queried using QAbstractItemModel::data() using Qt::DisplayRole.
All columns of the table must have unique names. They are queried using QAbstractItemModel::headerData() using Qt::Horizontal as orientation and Qt::DisplayRole.

Get/set the Qt table model.
It is expected that the QAbstractItemModel passed in is a QAbstractTableModel subclass; however allowing this class to work with a QAbstractItemModel is advantageous since it enables usage of proxy models, for example for sorting and filtering.
| QAbstractItemModel * QVTKTableModelAdapter::GetItemModel | ( | ) | const |
Get/set the Qt table model.
It is expected that the QAbstractItemModel passed in is a QAbstractTableModel subclass; however allowing this class to work with a QAbstractItemModel is advantageous since it enables usage of proxy models, for example for sorting and filtering.
| vtkTable * QVTKTableModelAdapter::GetTable | ( | ) | const |
Access to the vtkTable.
Treat this as a const object, i.e. you should not modify it outside of this class.
|
signal |
Signal emitted when the internal vtkTable has changed.
This signal can be used to connect to a slot which handles rendering of an attached chart.
|
protectedvirtual |
The default method for retrieving data for a table entry from the item model.
|
protectedvirtual |
Return a suitable vtk array for the QVariant type.
Note to call Delete() on the returned array where necessary, see vtkObjectBase::Delete() for details.
|
protectedvirtual |
Check that the correct array types are set for the columns.
|
protectedvirtual |
Sets the value of the cell given by row, column using the adequate QVariant type conversion.
|
protectedvirtual |
Update the internal table from row0 to inclusive row1, and from column0 to inclusive column1 so it reflects the data in the model.
