Member Function Documentation

getCommandActions()

virtual std::list< SoCommandAction * > SoInteractionProvider::getCommandActions ( SoState * state )

virtual

getInteractionProvider()

static SoInteractionProvider * SoInteractionProvider::getInteractionProvider ( SoNode * node )

static

Returns a SoInteractionProvider from a SoNode if registered, else NULL.

This is, e.g., used in the SoInteractionCollection class of the SoInteractionControllers library.

getInteractions()

virtual std::list< SoInteraction * > SoInteractionProvider::getInteractions ( SoState * state )

pure virtual

Returns the list of all interactions of this provider.

Implemented in SoInteractionOwner, and View2DInteractionProvider.

Referenced by getInteractionsOfType().

getInteractionsOfType()

template<class T >

std::list< T * > SoInteractionProvider::getInteractionsOfType

(

SoState *

state

)

Returns list of interactions of a specific type.

Definition at line 85 of file SoInteractionProvider.h.

getOffsetActions()

virtual std::list< SoOffsetAction * > SoInteractionProvider::getOffsetActions ( SoState * state )

virtual

getPointingActions()

virtual std::list< SoPointingAction * > SoInteractionProvider::getPointingActions ( SoState * state )

virtual

pointerLeftWindow()

virtual void SoInteractionProvider::pointerLeftWindow ( SoState * state )

pure virtual

This is called when the mouse cursor leaves the window.

Implemented in SoView2DRectangle, SoInteractionOwner, SoView2DLabel, SoView2DSliceZoom, and View2DInteractionProvider.

pointerPosition()

virtual void SoInteractionProvider::pointerPosition ( SoState * state, const SoPointerPosition & pos )

pure virtual

Override this to always be informed of the current mouse cursor position.

Implemented in SoView2DRectangle, SoInteractionOwner, SoPicking, SoView2DLabel, SoView2DSliceZoom, and View2DInteractionProvider.

registerInteractionProviderNode()

static void SoInteractionProvider::registerInteractionProviderNode ( SoType type, GetProviderFunc func )

static

Registers a function to obtain a SoInteractionProvider from a SoNode.
