Detailed Description

Qt table model for viewing and editing the constraints of a SimpleBarrierConstraintChecker.

This model adapts a mitk::SimpleBarrierConstraintChecker for use with a Qt table view. Each row represents a single constraint, with columns for: affected parameters, constraint type (upper/lower), barrier threshold value, penalty zone width, and parameter units. All columns except the unit column are editable.

Constructor & Destructor Documentation

◆ QmitkSimpleBarrierModel()

QmitkSimpleBarrierModel::QmitkSimpleBarrierModel ( QObject * parent = nullptr )

Constructs a QmitkSimpleBarrierModel.

Creates an empty internal SimpleBarrierConstraintChecker.

Parameters

[in] parent Optional parent QObject.

◆ ~QmitkSimpleBarrierModel()

QmitkSimpleBarrierModel::~QmitkSimpleBarrierModel ( )

inlineoverride

Destructor.

Member Function Documentation

◆ addConstraint()

void QmitkSimpleBarrierModel::addConstraint ( )

Adds a new default lower barrier constraint for parameter 0 with barrier value 0.

Triggers a full model reset and sets the modified flag.

◆ columnCount()

int QmitkSimpleBarrierModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const

override

Returns the number of columns (always 5).

Parameters

[in] parent The parent model index.

Returns: 5 (parameters, type, value, width, unit). Returns 0 if parent is valid.

◆ data()

QVariant QmitkSimpleBarrierModel::data	(	const QModelIndex &	index,
		int	role
	)		const

override

Returns data for the given index and role.

Column 0: affected parameter names (display: selected names; edit: all available names). Column 1: constraint type ("upper" or "lower"). Column 2: barrier threshold value. Column 3: penalty zone width. Column 4: units of the affected parameters.

Parameters

[in]	index	The model index to query.
[in]	role	The Qt item data role.

Returns: The requested data as QVariant.

◆ deleteConstraint()

void QmitkSimpleBarrierModel::deleteConstraint ( const QModelIndex & index )

Deletes the constraint at the specified model index.

Does nothing if the index is invalid or out of range. Triggers a full model reset and sets the modified flag.

Parameters

[in] index The model index of the constraint to delete.

◆ flags()

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

override

Returns item flags for the given model index.

Columns 0 through 3 (parameters, type, value, width) are editable. Column 4 (unit) is read-only.

Parameters

[in] index The model index to query.

Returns: The item flags.

◆ headerData()

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

override

Returns header data for the specified section.

Horizontal headers are: "Parameters", "Type", "Value", "Width", "Unit".

Parameters

[in]	section	The column index.
[in]	orientation	The header orientation.
[in]	role	The Qt item data role.

Returns: The header data as QVariant.

◆ isModified()

bool QmitkSimpleBarrierModel::isModified ( )

Indicates whether the model content has been modified since the last setChecker() call.

Returns: True if modified, false otherwise.

◆ rowCount()

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

override

Returns the number of constraints (rows).

Parameters

[in] parent The parent model index.

Returns: The number of constraints. Returns 0 if parent is valid.

◆ setChecker()

void QmitkSimpleBarrierModel::setChecker	(	mitk::SimpleBarrierConstraintChecker *	pChecker,
		const mitk::ModelTraitsInterface::ParameterNamesType &	names,
		const mitk::ModelTraitsInterface::ParamterUnitMapType	units
	)

Sets the constraint checker and parameter metadata managed by this model.

If the provided checker differs from the current one, the model is reset. The modified flag is cleared. If pChecker is nullptr, a new empty checker is created.

Parameters

[in]	pChecker	Pointer to the SimpleBarrierConstraintChecker to manage.
[in]	names	List of parameter names. The index corresponds to the parameter index in the fitting model.
[in]	units	Map of parameter names to their unit strings.

◆ setData()

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

override

Sets data for a given index.

Column 0: expects a QStringList of selected parameter names. Column 1: expects an integer (0 = lower, 1 = upper). Column 2: expects a double barrier value. Column 3: expects a double width value.

Parameters

[in]	index	The model index to modify.
[in]	value	The new value to set.
[in]	role	The Qt item data role (only Qt::EditRole is handled).

Returns: True if data was successfully modified, false otherwise.
