Detailed Description

Item delegate for rendering and editing dose values in a QTableView.

This delegate renders dose values right-aligned and creates a QDoubleSpinBox editor for editing. The delegate inspects Qt::UserRole+1 on the model to determine whether the dose is displayed as absolute (Gy) or relative (%). The spin box suffix and step size are adjusted accordingly.

Parameters

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

Returns

A QDoubleSpinBox for valid data, or a QLabel for invalid data.

paint()

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

override

Renders the dose value text right-aligned in the cell.

Parameters

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

setEditorData()

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

override

Populates the editor with the current dose value from the model.

Parameters

[in,out]	editor	The editor widget (QDoubleSpinBox) to populate.
[in]	index	The model index to read data from.

setModelData()

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

override

Commits the edited dose value from the spin box back to the model.

Parameters

[in]	editor	The editor widget (QDoubleSpinBox) containing the new value.
[in,out]	model	The model to write the new value to.
