Detailed Description

Toolkit includes.

Item delegate for rendering and editing the parameters of a barrier constraint.

This delegate handles the display and selection of parameters relevant to a barrier constraint. It assumes the following data conventions:

• Qt::EditRole data is a QStringList of all available parameter names.
• Qt::DisplayRole data is a QStringList of the currently selected parameter names.

The editor is a QListWidget with checkboxes, allowing multi-selection of parameters. When data is transferred back to the model, a QStringList of all checked parameter names is written.

Constructor & Destructor Documentation

QmitkSimpleBarrierParametersDelegate()

QmitkSimpleBarrierParametersDelegate::QmitkSimpleBarrierParametersDelegate

(

QObject *

parent = nullptr

)

Constructs a QmitkSimpleBarrierParametersDelegate.

Parameters

[in]

parent

Optional parent QObject.

Member Function Documentation

createEditor()

QWidget* QmitkSimpleBarrierParametersDelegate::createEditor ( QWidget *  parent, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Creates a QListWidget editor with checkable parameter name items.

If the edit role data is invalid, returns a read-only QLabel instead.

Parameters

[in]	parent	The parent widget for the editor.
[in]	option	Style options for the item.
[in]	index	The model index of the item being edited.

Returns

The newly created editor widget.

paint()

void QmitkSimpleBarrierParametersDelegate::paint ( QPainter *  painter, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Paints the selected parameter names as a comma-separated string.

If the display data is invalid, renders "Invalid data".

Parameters

[in]	painter	The QPainter to use for rendering.
[in]	option	Style options for the item.
[in]	index	The model index to paint.

setEditorData()

void QmitkSimpleBarrierParametersDelegate::setEditorData ( QWidget *  editor, const QModelIndex &  index  ) const

override

Populates the list widget with parameter names, checking currently selected ones.

Uses the edit role data for the full list and the display role data for checked items.

Parameters

[in]	editor	The editor widget (expected to be a QListWidget).
[in]	index	The model index of the item.

setModelData()

void QmitkSimpleBarrierParametersDelegate::setModelData ( QWidget *  editor, QAbstractItemModel *  model, const QModelIndex &  index  ) const

override

Transfers the checked parameter names from the list widget back to the model.

Parameters

[in]	editor	The editor widget containing the selections.
[in,out]	model	The abstract item model to update.
[in]	index	The model index of the item.
