Detailed Description

A selection service tracks the selection within an object.

A listener that wants to be notified when the selection becomes null must implement the INullSelectionListener interface.

This interface is not intended to be implemented by clients.

Member Function Documentation

virtual void berry::ISelectionService::AddPostSelectionListener ( ISelectionListener *  listener )

pure virtual

Adds the given post selection listener.It is equivalent to selection changed if the selection was triggered by the mouse but it has a delay if the selection is triggered by the keyboard arrows. Has no effect if an identical listener is already registered.

Note: Works only for StructuredViewer(s).

Parameters

listener

a selection listener

virtual void berry::ISelectionService::AddPostSelectionListener ( const QString &  partId, ISelectionListener *  listener  )

pure virtual

Adds a part-specific selection listener which is notified when selection changes in the part with the given id. This is independent of part activation - the part need not be active for notification to be sent.

When the part is created, the listener is passed the part's initial selection. When the part is disposed, the listener is passed a null selection, but only if the listener implements INullSelectionListener.

Note: This will not correctly track editor parts as each editor does not have a unique partId.

Parameters

partId	the id of the part to track
listener	a selection listener

virtual void berry::ISelectionService::AddSelectionListener ( ISelectionListener *  listener )

pure virtual

Adds the given selection listener. Has no effect if an identical listener is already registered.

Parameters

listener

a selection listener

virtual void berry::ISelectionService::AddSelectionListener ( const QString &  partId, ISelectionListener *  listener  )

pure virtual

Adds a part-specific selection listener which is notified when selection changes in the part with the given id. This is independent of part activation - the part need not be active for notification to be sent.

When the part is created, the listener is passed the part's initial selection. When the part is disposed, the listener is passed a null selection, but only if the listener implements INullSelectionListener.

Note: This will not correctly track editor parts as each editor does not have a unique partId.

Parameters

partId	the id of the part to track
listener	a selection listener

Since

2.0

virtual ISelection::ConstPointer berry::ISelectionService::GetSelection ( ) const

pure virtual

Returns the current selection in the active part. If the selection in the active part is undefined (the active part has no selection provider) the result will be null.

Returns

the current selection, or null if undefined

virtual ISelection::ConstPointer berry::ISelectionService::GetSelection ( const QString &  partId )

pure virtual

Returns the current selection in the part with the given id. If the part is not open, or if the selection in the active part is undefined (the active part has no selection provider) the result will be null.

Parameters

partId

the id of the part

Returns

the current selection, or null if undefined

Since

2.0

virtual void berry::ISelectionService::RemovePostSelectionListener ( ISelectionListener *  listener )

pure virtual

Removes the given post selection listener. Has no effect if an identical listener is not registered.

Parameters

listener

a selection listener

Referenced by QmitkFunctionality::ClosePartProxy(), and QmitkAbstractView::~QmitkAbstractView().

virtual void berry::ISelectionService::RemovePostSelectionListener ( const QString &  partId, ISelectionListener *  listener  )

pure virtual

Removes the given part-specific post selection listener. Has no effect if an identical listener is not registered for the given part id.

Parameters

partId	the id of the part to track
listener	a selection listener

Since

2.0

virtual void berry::ISelectionService::RemoveSelectionListener ( ISelectionListener *  listener )

pure virtual

Removes the given selection listener. Has no effect if an identical listener is not registered.

Parameters

listener

a selection listener

virtual void berry::ISelectionService::RemoveSelectionListener ( const QString &  partId, ISelectionListener *  listener  )

pure virtual

Removes the given part-specific selection listener. Has no effect if an identical listener is not registered for the given part id.

Parameters

partId	the id of the part to track
listener	a selection listener

Since

2.0
