IsDisplayAccepted()

virtual bool iview::IVisualizable::IsDisplayAccepted ( const IDisplay &  display ) const

pure virtual

Check if this object can be connected to this display.

Implemented in iview::CShapeBase.

IsVisible()

virtual bool iview::IVisualizable::IsVisible ( ) const

pure virtual

Check, if this object is visible.

Implemented in iview::CShapeBase.

OnConnectDisplay()

virtual void iview::IVisualizable::OnConnectDisplay ( IDisplay *  displayPtr )

pure virtual

Called after display is connected.

It can be called only, when display is accepted (

See also

IsDisplayAccepted()).

Parameters

displayPtr

an observer object, which should be informed about all shape changes.

Implemented in iview::CShapeBase.

OnDisconnectDisplay()

virtual void iview::IVisualizable::OnDisconnectDisplay ( IDisplay *  displayPtr )

pure virtual

Called after display is disconnected.

Note, that this display must be previously connected.

Parameters

displayPtr

a disconnected observer object.

Implemented in iview::CShapeBase.

OnDisplayChange()

virtual bool iview::IVisualizable::OnDisplayChange ( const istd::IChangeable::ChangeSet &  changeSet )

pure virtual

It informs about changes in display.

It is called e.g. after view transformation change.

Returns

true, if this change follow shape changes.

Implemented in iview::CShapeBase.
