34 \class SoInteraction SoInteraction.h Inventor/SoInteraction.h
35 \brief The SoInteraction class takes care of initalizing internal classes.
36
37 \ingroup general
38
39 SoInteraction is present for the sole purpose of providing an
40 interface to the initialization methods of the classes in Coin which
41 are somehow related to user interaction, like the draggers and
42 manipulators.
43
44 It is unlikely that the application programmer should need to worry
45 about this class, as SoInteraction::init() is called by the GUI
46 specific initialization methods.

94 Calls the initClass() method of these classes: SoAntiSquish,
95 SoSelection, SoExtSelection, SoSurroundScale, SoInteractionKit,
96 SoDragger, SoClipPlaneManip, SoDirectionalLightManip,
97 SoPointLightManip, SoSpotLightManip, SoTransformManip,
98 SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip,
99 SoTrackballManip, SoTransformBoxManip, SoTransformerManip.
100
101 Note that this method calls SoDB::init() and SoNodeKit::init() to
102 make sure all classes that the interaction functionality depends on
103 have been initialized.
104
105
106 Application programmers should usually not have to invoke this method
107 directly from application code, as it is indirectly called from the
108 GUI-binding libraries' init()-functions. Only if you are using your own
109 GUI-binding (and not one of Kongsberg Oil & Gas Technologies's SoQt, SoGtk,
110 SoXt, SoWin, Sc21 etc. libraries) do you have to explicitly call
111 SoInteraction::init().
