◆ ConnectShape()

virtual bool iview::IShapeView::ConnectShape ( IShape * shapePtr )

pure virtual

Connect shape object to view.

Parameters

shapePtr pointer shape object, will be not owned by this view.

Returns: true, if it was possible to connect this shape.

Implemented in iview::CViewBase.

Referenced by i2dgui::TViewExtenderCompBase< Base >::AddItemsToScene().

◆ GetFocusedLayerPtr()

virtual ISelectableLayer * iview::IShapeView::GetFocusedLayerPtr ( ) const

pure virtual

Get focused layer.

Implemented in iview::CViewBase.

◆ GetLayer()

virtual IViewLayer & iview::IShapeView::GetLayer ( int index ) const

pure virtual

Get layer with the given index.

Implemented in iview::CViewBase.

◆ GetLayerIndex() [1/2]

virtual int iview::IShapeView::GetLayerIndex ( const IViewLayer & layer ) const

pure virtual

Get index of layer.

Returns: layer index, or -1 if not found.

Implemented in iview::CViewBase.

◆ GetLayerIndex() [2/2]

virtual int iview::IShapeView::GetLayerIndex ( int layerType ) const

pure virtual

Get index of layer by type.

Returns: layer index, or -1 if not found.
