Detailed Description

A tree model that exposes the properties of a mitk::PropertyList.

This model builds a two-column tree (property name and value) from a mitk::PropertyList. Property names containing dots are automatically grouped into a tree hierarchy. The model supports editing via QmitkPropertyItemDelegate, filters properties based on the configured class name via mitk::IPropertyFilters, and resolves property aliases via mitk::IPropertyAliases.

[in]	role	The data role (Qt::DisplayRole, Qt::EditRole, mitk::PropertyRole, etc.).

Returns

The data as QVariant.

flags()

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

headerData()

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

override

Returns header data for the given section.

Parameters

[in]	section	The section (0 = "Property", 1 = "Value").
[in]	orientation	The orientation.
[in]	role	The data role.

Returns

The header data as QVariant.

index()

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

override

Returns the model index for the given row and column.

Parameters

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

Returns

The model index.

parent()

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

override

Returns the parent index for the given child index.

Parameters

[in]

child

The child index.

Returns

The parent index.

rowCount()

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

override

Returns the number of rows (child properties) under the given parent.

Parameters

[in]

parent

The parent index.

Returns

The row count.

setData()

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

override

Sets the property value at the given index.

Parameters

[in]	index	The model index (must be in the value column).
[in]	value	The new value.
[in]	role	The data role (must be Qt::EditRole).

Returns

True if the value was set successfully.

SetPropertyList()

void QmitkPropertyItemModel::SetPropertyList	(	mitk::PropertyList *	propertyList,
		const QString &	className = ""
	)

Sets the property list and optional class name for filtering.

Parameters

[in]	propertyList	The property list to display.
[in]	className	Optional class name used for property filtering and alias resolution.

Update()

void QmitkPropertyItemModel::Update

(

)

Forces a complete rebuild of the model from the current property list.
