void select(const QItemSelection &selection, QItemSelectionModel::SelectionFlags command) override
Overwritten to do NOTHING (we handle selection ourselves)
void requestRepaint(const QModelIndexList &indexes)
Request a repaint of a list of model indexes.
void requestRepaint()
Request a repaint of the visible items of connected views.
void select(const QModelIndex &index, QItemSelectionModel::SelectionFlags command) override
Overwritten to do NOTHING (we handle selection ourselves)
Is an interface class to abstract feature selection handling.
Represents a vector layer which manages a vector based data sets.
