Constructor & Destructor Documentation

QmitkImageStatisticsTreeItem() [1/3]

QmitkImageStatisticsTreeItem::QmitkImageStatisticsTreeItem

(

)

Default constructor. Creates an empty item with no statistics data.

QmitkImageStatisticsTreeItem() [2/3]

QmitkImageStatisticsTreeItem::QmitkImageStatisticsTreeItem ( const ImageStatisticsObject &  statisticsData, const StatisticNameVector &  statisticNames, QVariant  itemText, bool  isWIP, QmitkImageStatisticsTreeItem *  parentItem = nullptr, const mitk::DataNode *  imageNode = nullptr, const mitk::DataNode *  maskNode = nullptr, const mitk::Label *  label = nullptr  )

explicit

Construct a tree item holding actual statistics data.

Parameters

statisticsData	The image statistics object containing the computed values.
statisticNames	Names of the statistics to display as columns.
itemText	Display text for this tree item.
isWIP	True if the statistics are still being computed (work in progress).
parentItem	Optional parent item in the tree hierarchy.
imageNode	Optional data node for the image.
maskNode	Optional data node for the mask.
label	Optional label associated with this item.

QmitkImageStatisticsTreeItem() [3/3]

QmitkImageStatisticsTreeItem::QmitkImageStatisticsTreeItem ( const StatisticNameVector &  statisticNames, QVariant  itemText, bool  isWIP, bool  isNA, QmitkImageStatisticsTreeItem *  parentItem = nullptr, const mitk::DataNode *  imageNode = nullptr, const mitk::DataNode *  maskNode = nullptr, const mitk::Label *  label = nullptr  )

explicit

Construct a tree item without statistics data (e.g. a group header).

Parameters

statisticNames	Names of the statistics to display as columns.
itemText	Display text for this tree item.
isWIP	True if the statistics are still being computed.
isNA	True if the statistics are not applicable for this item.
parentItem	Optional parent item in the tree hierarchy.
imageNode	Optional data node for the image.
maskNode	Optional data node for the mask.
label	Optional label associated with this item.

Member Function Documentation

appendChild()

void QmitkImageStatisticsTreeItem::appendChild

(

QmitkImageStatisticsTreeItem *

child

)

Append a child item to this item.

Parameters

child

The child item to add. This item takes ownership.

child()

QmitkImageStatisticsTreeItem* QmitkImageStatisticsTreeItem::child

(

int

row

)

Return the child item at the given row.

Parameters

row	The row index.

Returns

The child item, or nullptr if out of range.

childCount()

int QmitkImageStatisticsTreeItem::childCount

(

)

const

Return the number of child items.

columnCount()

int QmitkImageStatisticsTreeItem::columnCount

(

)

const

Return the number of data columns.

data()

QVariant QmitkImageStatisticsTreeItem::data

(

int

column

)

const

Return the data for the given column.

Parameters

column

The column index.

Returns

The data value as QVariant.

GetLabelInstance()

mitk::Label::ConstPointer QmitkImageStatisticsTreeItem::GetLabelInstance

(

)

const

Return the label instance associated with this item, or nullptr.

isWIP()

bool QmitkImageStatisticsTreeItem::isWIP

(

)

const

Indicate whether the statistics are still being computed (work in progress).

Returns true if the statistic container owned by this instance is only a dummy WIP container and the calculation of the up-to-date statistic is not yet finished.

parentItem()

QmitkImageStatisticsTreeItem* QmitkImageStatisticsTreeItem::parentItem

(

)

Return the parent item, or nullptr if this is the root.

row()

int QmitkImageStatisticsTreeItem::row

(

)

const

Return this item's row index within its parent.
