Member Function Documentation

◆ canFetchMore()

bool QAndroidItemModelProxy::canFetchMore ( const QModelIndex & parent ) const

overridevirtual

Returns {true} if there is more data available for parent; otherwise returns {false}.

The default implementation always returns {false}.

If canFetchMore() returns true, the fetchMore() function should be called. This is the behavior of QAbstractItemView, for example.

◆ columnCount()

jint QAndroidItemModelProxy::columnCount ( const QModelIndex & parent = QModelIndex() ) const

overridevirtual

Returns the number of columns for the children of the given parent.

In most subclasses, the number of columns is independent of the parent.

For example:

int MyModel::columnCount(const QModelIndex &parent) const
{
    Q_UNUSED(parent);
    return 3;
}

Note: When implementing a table based model, columnCount() should return 0 when the parent is valid.
