Detailed Description

Implement Viewable if you want to be able to receive events when a View is created and/or deleted.

You'll want to receive these events if you either want to influence something on-screen (PresentationInterface, ColormapProvider), or want to store data related to a View (TiledBitmapInterface).

Member Typedef Documentation

Ptr

using Viewable::Ptr = boost::shared_ptr<Viewable>

WeakPtr

using Viewable::WeakPtr = boost::weak_ptr<Viewable>

Member Function Documentation

close()

virtual void Viewable::close ( ViewInterface::WeakPtr  vi )

pure virtual

Gets called just before the View is destroyed

Precondition

Should be called from within a Gdk critical section (i.e. between gdk_threads_enter() and gdk_threads_leave() calls)

Implemented in anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub, DummyPresentation, Layer, CompressedTile, PresentationBase, TransformPresentation, TiledBitmap, Scroom::ColormapImpl::ColormapProvider, and ExamplePresentation.

open()

virtual void Viewable::open ( ViewInterface::WeakPtr  vi )

pure virtual

Gets called just after the View is created

Precondition

Should be called from within a Gdk critical section (i.e. between gdk_threads_enter() and gdk_threads_leave() calls)

Implemented in anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub, DummyPresentation, TiledBitmap, ExamplePresentation, Layer, CompressedTile, PresentationBase, TransformPresentation, and Scroom::ColormapImpl::ColormapProvider.
