Detailed Description

Tree model that represents mitk::ImageStatisticsContainer data in the Qt model/view framework.

This model queries the data storage for ImageStatisticsContainer objects matching the configured image nodes, mask nodes, histogram bin count, and zero-voxel ignore flag. The results are presented in a hierarchical tree structure:

Level 1: Image
Level 2: Mask (if present)
Level 3: Label instances (if the mask has multiple labels)
Level 4: Time steps (if more than one exists)

Constructor & Destructor Documentation

◆ QmitkImageStatisticsTreeModel()

QmitkImageStatisticsTreeModel::QmitkImageStatisticsTreeModel ( QObject * parent = nullptr )

Constructs the tree model.

Parameters

[in] parent Optional parent QObject.

◆ ~QmitkImageStatisticsTreeModel()

QmitkImageStatisticsTreeModel::~QmitkImageStatisticsTreeModel ( )

override

Destructor. Disconnects from the data storage.

Member Function Documentation

◆ Clear()

void QmitkImageStatisticsTreeModel::Clear ( )

Clears all image nodes, mask nodes, statistics, and resets the model.

◆ columnCount()

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

override

Returns the number of columns (statistic names count + 1).

Parameters

[in] parent The parent model index (unused).

Returns: The number of columns.

◆ data()

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

override

Returns the data for the given index and role.

Supports Qt::DisplayRole for statistics values and Qt::DecorationRole for label color icons and WIP hourglass indicators in the first column.

Parameters

[in]	index	The model index to query.
[in]	role	The data role (e.g. Qt::DisplayRole, Qt::DecorationRole).

Returns: The data as QVariant, or an invalid QVariant if not applicable.

◆ dataAvailable

void QmitkImageStatisticsTreeModel::dataAvailable ( )

signal

Emitted when new statistics data becomes available in the model.

◆ DataStorageChanged()

void QmitkImageStatisticsTreeModel::DataStorageChanged ( )

overrideprotectedvirtual

Implements QmitkAbstractDataStorageModel.

◆ flags()

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

override

Returns the item flags for the given model index.

Parameters

[in] index The model index to query.

Returns: The Qt item flags for the index.

◆ GetHistogramNBins()

unsigned int QmitkImageStatisticsTreeModel::GetHistogramNBins ( ) const

Returns the current number of histogram bins.

Returns: The number of histogram bins.

◆ GetIgnoreZeroValueVoxel()

bool QmitkImageStatisticsTreeModel::GetIgnoreZeroValueVoxel ( ) const

Returns whether zero-valued voxels are currently being ignored.

Returns: True if zero-valued voxels are ignored; false otherwise.

◆ headerData()

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

override

Returns the header data for the given section and orientation.

The first column header is dynamically generated based on whether masks and multiple time steps are present. Subsequent columns show statistic names.

Parameters

[in]	section	The column index.
[in]	orientation	The header orientation (only Qt::Horizontal is supported).
[in]	role	The data role (only Qt::DisplayRole is supported).

Returns: The header text as QVariant.

◆ index()

QModelIndex QmitkImageStatisticsTreeModel::index	(	int	row,
		int	column,
		const QModelIndex &	parent = `QModelIndex()`
	)		const

override

Returns the model index for the specified row, column, and parent.

Parameters

[in]	row	The row number.
[in]	column	The column number.
[in]	parent	The parent model index.

Returns: The model index for the child, or an invalid index if it does not exist.

◆ modelChanged

void QmitkImageStatisticsTreeModel::modelChanged ( )

signal

Emitted when the model rebuild is finished (usually shortly after dataAvailable()).

◆ NodeAdded()

void QmitkImageStatisticsTreeModel::NodeAdded ( const mitk::DataNode * node )

overrideprotectedvirtual

Implements QmitkAbstractDataStorageModel.

◆ NodeChanged()

void QmitkImageStatisticsTreeModel::NodeChanged ( const mitk::DataNode * node )

overrideprotectedvirtual

overrideprotectedvirtual

Implements QmitkAbstractDataStorageModel.

◆ NodeRemoved()

void QmitkImageStatisticsTreeModel::NodeRemoved ( const mitk::DataNode * node )

overrideprotectedvirtual

Implements QmitkAbstractDataStorageModel.

◆ parent()

QModelIndex QmitkImageStatisticsTreeModel::parent ( const QModelIndex & child ) const

override

Returns the parent model index of the given child.

Parameters

[in] child The child model index.

Returns: The parent model index, or an invalid index if the child is at the root level.

◆ rowCount()

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

override

Returns the number of child rows under the given parent.

Parameters

[in] parent The parent model index. Invalid index refers to the root.

Returns: The number of child rows.

◆ SetHistogramNBins()

void QmitkImageStatisticsTreeModel::SetHistogramNBins ( unsigned int nbins )

Sets the number of histogram bins used to select matching statistics.

Triggers a model reset and rebuild if the value changes.

Parameters

[in] nbins The number of histogram bins.

◆ SetIgnoreZeroValueVoxel()

void QmitkImageStatisticsTreeModel::SetIgnoreZeroValueVoxel ( bool _arg )

Sets whether zero-valued voxels should be ignored when selecting statistics.

Triggers a model reset and rebuild if the value changes.

Parameters

[in] _arg True to ignore zero-valued voxels; false to include them.

◆ SetImageNodes()

void QmitkImageStatisticsTreeModel::SetImageNodes ( const std::vector< mitk::DataNode::ConstPointer > & nodes )

Sets the image nodes whose statistics should be displayed.

Internally resolves each image's time steps for the hierarchical model. Triggers a model reset and rebuild.

Parameters
