Detailed Description

Qt table model for displaying parameter values of model fit results at various world positions.

This model presents the parameter values of one or more ModelFitInfo instances evaluated at the current world coordinate position and optional bookmark positions. When a single fit is provided, the model displays a flat list of parameters. When multiple fits are present, the model uses a tree hierarchy where the first level represents fits and the second level represents the parameters of each fit.

Columns are organized as: parameter name, parameter type, value at the current position, and one additional column per bookmark position.

Member Function Documentation

◆ columnCount()

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

override

Returns the number of columns in the model.

Always returns 3 (name, type, current value) plus the number of bookmark positions.

Parameters

[in] parent The parent model index.

Returns: The column count.

◆ data()

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

override

Returns data for the given index and role.

Provides parameter names (column 0), parameter types (column 1), values at the current position (column 2), and values at bookmark positions (columns 3+). Static parameters are displayed with comma-separated values. When multiple fits are set, the top-level rows show fit name and UID.

Parameters

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

Returns: The requested data as QVariant, or an invalid QVariant if unavailable.

◆ flags()

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

override

Returns item flags for the given model index.

Parameters

[in] index The model index to query.

Returns: The item flags (read-only by default).

◆ getBookmarksCount()

std::size_t QmitkFitParameterModel::getBookmarksCount ( ) const

protected

◆ getCurrentPosition()

mitk::Point3D QmitkFitParameterModel::getCurrentPosition ( ) const

Returns the current world coordinate position used for value lookup.

Returns: The current 3D position.

◆ getFits()

const FitVectorType& QmitkFitParameterModel::getFits ( ) const

Returns the currently set model fit info instances.

Returns: Const reference to the vector of ModelFitInfo pointers.

◆ getPositionBookmarks()

const mitk::PointSet* QmitkFitParameterModel::getPositionBookmarks ( ) const

Returns the point set used as position bookmarks.

Returns: Pointer to the position bookmark PointSet, or nullptr if none is set.

◆ headerData()

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

override

Returns header data for the specified section, orientation, and role.

Horizontal headers are: "Name", "Type", "Value", and positional headers for each bookmark showing coordinates.

Parameters

[in]	section	The column index.
[in]	orientation	The header orientation (horizontal or vertical).
[in]	role	The Qt item data role.

Returns: The header data as QVariant.

◆ rowCount()

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

override

Returns the number of rows in the model.

For a single fit, returns the number of parameters plus static parameters. For multiple fits, the top-level row count equals the number of fits, and child row counts equal the parameter counts of each respective fit.

Parameters

[in] parent The parent model index.

Returns: The row count.

◆ setCurrentPosition

void QmitkFitParameterModel::setCurrentPosition ( const mitk::Point3D & currentPos )

slot

Sets the current world coordinate position for parameter value lookup.

Triggers a full model reset so that values are re-read at the new position.

Parameters

[in] currentPos The new 3D world position.

◆ setData()

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

override

Sets data for a given index (currently always returns false; model is read-only).

Parameters

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

Returns: Always false.

◆ setFits

void QmitkFitParameterModel::setFits ( const FitVectorType & fits )

slot

Sets the model fit info instances to display.

Triggers a full model reset.

Parameters

[in] fits Vector of ModelFitInfo pointers to display.

◆ setPositionBookmarks

void QmitkFitParameterModel::setPositionBookmarks ( const mitk::PointSet * bookmarks )

slot

Sets the point set used as position bookmarks.

Each bookmark adds an additional column to the model showing parameter values at that position. Triggers a full model reset.

Parameters

[in] bookmarks Pointer to a PointSet of bookmark positions, or nullptr to clear.
