ConnectShape()

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

pure virtual

Connect shape object to view.

Parameters

shape	a shape object.
active	if true, shape will be active, if false it will be only visible.

Returns

true, if it was possible to connect this shape.

Implemented in iview::CInteractiveViewLayer, and iview::CViewLayer.

DisconnectAllShapes()

virtual void iview::IViewLayer::DisconnectAllShapes ( )

pure virtual

Disconnect all shapes from this layer.

Implemented in iview::CInteractiveViewLayer, and iview::CViewLayer.

DrawShapes()

virtual void iview::IViewLayer::DrawShapes ( QPainter & drawContext )

pure virtual

Draw all shapes using specified draw context.

Implemented in iview::CInteractiveViewLayer, and iview::CViewLayer.

GetShapes()

virtual Shapes iview::IViewLayer::GetShapes ( ) const

pure virtual

Get all shapes on this layer.

Implemented in iview::CViewLayer.

GetShapesCount()

virtual int iview::IViewLayer::GetShapesCount ( ) const

pure virtual

Get count of all shapes on this layer.

Implemented in iview::CInteractiveViewLayer, and iview::CViewLayer.

GetViewPtr()

virtual IShapeView * iview::IViewLayer::GetViewPtr ( ) const

pure virtual

Get parent view of this layer.

It can be used only when view is connected.

Implemented in iview::CViewLayer.

IsShapeConnected()

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

pure virtual

Check, if this layer is visible.

Implemented in iview::CViewLayer.

OnConnectView()

virtual void iview::IViewLayer::OnConnectView ( IShapeView * viewPtr )

pure virtual

Called after layer is connected to view.

Implemented in iview::CViewLayer.

OnDisconnectView()

virtual void iview::IViewLayer::OnDisconnectView ( IShapeView * viewPtr )

pure virtual

Called before layer is disconnected from view.

Implemented in iview::CViewLayer.
