◆ clearItemData()

bool QTableModel::clearItemData ( const QModelIndex & index )

overridevirtual

Since: 6.0 Removes the data stored in all the roles for the given index. Returns {true} if successful; otherwise returns {false}. The dataChanged() signal should be emitted if the data was successfully removed. The base class implementation returns {false}

Reimplemented from QAbstractItemModel.

Definition at line 467 of file qtablewidget.cpp.

◆ columnCount()

int QTableModel::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.

◆ mimeData()

QMimeData * QTableModel::mimeData ( const QModelIndexList & indexes ) const

overridevirtual

Returns an object that contains serialized items of data corresponding to the list of indexes specified.

The format used to describe the encoded data is obtained from the mimeTypes() function. This default implementation uses the default MIME type returned by the default implementation of mimeTypes(). If you reimplement mimeTypes() in your custom model to return more MIME types, reimplement this function to make use of them.

If the list of indexes is empty, or there are no supported MIME types, \nullptr is returned rather than a serialized empty list.

Reimplemented from QAbstractItemModel.

◆ mimeTypes()

QStringList QTableModel::mimeTypes ( ) const

overridevirtual

Returns the list of allowed MIME types.

By default, the built-in models and views use an internal MIME type: {application/x-qabstractitemmodeldatalist}.

When implementing drag and drop support in a custom model, if you will return data in formats other than the default internal MIME type, reimplement this function to return your list of MIME types.

If you reimplement this function in your custom model, you must also reimplement the member functions that call it: mimeData() and dropMimeData().

		const QModelIndex &	parent = QModelIndex() )

override

Definition at line 62 of file qtablewidget.cpp.

◆ rowCount()

int QTableModel::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.

Implements QAbstractItemModel.

◆ setColumnCount()

void QTableModel::setColumnCount ( int columns )

Definition at line 364 of file qtablewidget.cpp.

◆ setData()

bool QTableModel::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.

Reimplemented from QAbstractItemModel.

Definition at line 393 of file qtablewidget.cpp.

◆ setHeaderData()

bool QTableModel::setHeaderData	(	int	section,
		Qt::Orientation	orientation,
		const QVariant &	value,
		int	role )

overridevirtual

Sets the data for the given role and section in the header with the specified orientation to the value supplied.

Returns {true} if the header's data was updated; otherwise returns {false}.

When reimplementing this function, the headerDataChanged() signal must be emitted explicitly.

Definition at line 157 of file qtablewidget.cpp.

◆ setItemData()

bool QTableModel::setItemData	(	const QModelIndex &	index,
		const QMap< int, QVariant > &	roles )

overridevirtual

Sets the role data for the item at index to the associated value in roles, for every Qt::ItemDataRole.

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

Roles that are not in roles will not be modified.

◆ supportedDropActions()

Qt::DropActions QTableModel::supportedDropActions ( ) const

overridevirtual

Since: 4.2

Returns the drop actions supported by this model.

The default implementation returns Qt::CopyAction. Reimplement this function if you wish to support additional actions. You must also reimplement the dropMimeData() function to handle the additional operations.
