◆ dropMimeData()

bool QTreeModel::dropMimeData	(	const QMimeData *	data,
		Qt::DropAction	action,
		int	row,
		int	column,
		const QModelIndex &	parent
	)

virtual

Handles the data supplied by a drag and drop operation that ended with the given action.

Returns true if the data and action can be handled by the model; otherwise returns false.

The specified row, column and parent indicate the location of an item in the model where the operation ended. It is the responsibility of the model to complete the action at the correct location.

For instance, a drop action on an item in a QTreeView can result in new items either being inserted as children of the item specified by row, column, and parent, or as siblings of the item.

When row and column are -1 it means that the dropped data should be considered as dropped directly on parent. Usually this will mean appending the data as child items of parent. If row and column are greater than or equal zero, it means that the drop occurred just before the specified row and column in the specified parent.

◆ supportedDropActions()

Qt::DropActions QTreeModel::supportedDropActions ( ) const

virtual

Returns the drop actions supported by this model.

Since: 4.2

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.

See also: dropMimeData(), Qt::DropActions, {Using drag and drop with item views}

Reimplemented from QAbstractItemModel.

◆ timerEvent()

void QTreeModel::timerEvent ( QTimerEvent * event )

protectedvirtual

This event handler can be reimplemented in a subclass to receive timer events for the object.

QTimer provides a higher-level interface to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.

See also: startTimer(), killTimer(), event()

Reimplemented from QObject.
