columnCount()

int QQmlTreeModelToTableModel::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.

flags()

Qt::ItemFlags QQmlTreeModelToTableModel::flags ( const QModelIndex & index ) const

overridevirtual

Returns the item flags for the given index.

The base class implementation returns a combination of flags that enables the item (ItemIsEnabled) and allows it to be selected (ItemIsSelectable).

hasChildren() [1/2]

bool QAbstractItemModel::hasChildren ( const QModelIndex & parent = QModelIndex() ) const

virtual

Returns {true} if parent has any children; otherwise returns {false}.

Use rowCount() on the parent to find out the number of children.

Note that it is undefined behavior to report that a particular index hasChildren with this method if the same index has the flag Qt::ItemNeverHasChildren set.

headerData()

QVariant QQmlTreeModelToTableModel::headerData ( int section, Qt::Orientation orientation, int role ) const

overridevirtual

Returns the data for the given role and section in the header with the specified orientation.

For horizontal headers, the section number corresponds to the column number. Similarly, for vertical headers, the section number corresponds to the row number.

Returns the index of the item in the model specified by the given row, column and parent index.

When reimplementing this function in a subclass, call createIndex() to generate model indexes that other components can use to refer to items in your model.

roleNames()

Since

4.6

Returns the model's role names.

The default role names set by Qt are:

\table \header

• Qt Role
• QML Role Name \row
• Qt::DisplayRole
• display \row
• Qt::DecorationRole
• decoration \row
• Qt::EditRole
• edit \row
• Qt::ToolTipRole
• toolTip \row
• Qt::StatusTipRole
• statusTip \row
• Qt::WhatsThisRole
• whatsThis \endtable

Reimplemented from QAbstractItemModel.

rowCount()

int QQmlTreeModelToTableModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const

overridevirtual

Returns the number of rows under the given parent.

When the parent is valid it means that rowCount is returning the number of children of parent.

Note

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

setData()

bool QQmlTreeModelToTableModel::setData ( const QModelIndex & index, const QVariant & value, int role )

overridevirtual

Sets the role data for the item at index to value.

Returns {true} if successful; otherwise returns {false}.

The dataChanged() signal should be emitted if the data was successfully set.

The base class implementation returns {false}. This function and data() must be reimplemented for editable models.
