Detailed Description

QAbstractProxyModel implementation that groups data in a source-model according to a specified GroupingOption.

Note

This model is reset every time new data is added/moved/removed from the Data Model and if the GroupingOption is changed. This model should not be used without a source-model. Data can be grouped by Study-ID (GroupingOption::StudyId), Patient-ID (GroupingOption::PatientId), or not grouped (GroupingOption::None)

Public Types
enum class	GroupingOption { StudyId = 0 , PatientId = 1 , None = 2 }
	Specific grouping options to gather the corresponding info from the ImageInfoDataComponent.

Public Member Functions
	DataGroupingModel (GroupingOption opt, QAbstractItemModel *sourceModel=nullptr, QObject *parent=nullptr)
	Ctor: pass the option for grouping the data and the source model. If you prefer you can also set the source model via setSourceModel.
int	columnCount (const QModelIndex &parent=QModelIndex()) const override
	QAbstractItemModel interface implementation.
int	rowCount (const QModelIndex &parent=QModelIndex()) const override
QVariant	data (const QModelIndex &index, int role=Qt::DisplayRole) const override
QModelIndex	index (int row, int column, const QModelIndex &parent=QModelIndex()) const override
QModelIndex	parent (const QModelIndex &index) const override
QModelIndex	buddy (const QModelIndex &index) const override
QModelIndex	index (const Data *, int column) const
Qt::ItemFlags	flags (const QModelIndex &index) const override
QModelIndex	mapFromSource (const QModelIndex &sourceIndex) const override
	QAbstractProxyModel interface implementation.
QModelIndex	mapToSource (const QModelIndex &proxyIndex) const override
bool	setData (const QModelIndex &index, const QVariant &value, int role=Qt::EditRole) override
void	setSourceModel (QAbstractItemModel *sourceModel) override
	sets the source model and resets this model
void	setGroupingOption (GroupingOption opt)
	sets the GroupingOption and resets this model
GroupingOption	groupingOption () const
Public Member Functions inherited from ImFusion::SignalReceiver
	SignalReceiver ()=default
	Default constructor.
	SignalReceiver (const SignalReceiver &other)
	Copy constructor, does not copy any existing signal connections from other.
SignalReceiver &	operator= (SignalReceiver rhs)
	Assignment operator, disconnects all existing connections, does not copy any existing signal connections from rhs.
virtual	~SignalReceiver ()
	Virtual destructor disconnects from all connected signals.

Public Attributes
Signal< QModelIndex >	signalGroupAdded
	Signals that a group was added - connect to this e.g. to expand items in the DataWidget.
