Member Function Documentation

columnCount()

int QHeaderDataProxyModel::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.

Here is the caller graph for this function:

data()

QVariant QHeaderDataProxyModel::data ( const QModelIndex & index, int role = Qt::DisplayRole ) const

overridevirtual

Returns the data stored under the given role for the item referred to by the index.

Note

If you do not have a value to return, return an invalid (default-constructed) QVariant.

Here is the call graph for this function:

hasChildren()

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

overridevirtual

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.

index()

QModelIndex QHeaderDataProxyModel::index ( int row, int column, const QModelIndex & parent = QModelIndex() ) const

overridevirtual

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()

QHash< int, QByteArray > QHeaderDataProxyModel::roleNames ( ) const

overridevirtual

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::WhatsThisRole
• whatsThis \endtable

Here is the call graph for this function:

rowCount()

int QHeaderDataProxyModel::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 QHeaderDataProxyModel::setData ( const QModelIndex & index, const QVariant & value, int role = Qt::EditRole )

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.

QModelIndex QHeaderDataProxyModel::sibling ( int row, int column, const QModelIndex & index ) const

overridevirtual

Returns the sibling at row and column for the item at index, or an invalid QModelIndex if there is no sibling at that location.

sibling() is just a convenience function that finds the item's parent, and uses it to retrieve the index of the child item in the specified row and column.

This method can optionally be overridden for implementation-specific optimization.
