The dragger's constructor gets the scene graph for 'ResourceName' 00059 | by querying the global dictionary ( SoDB::getByName("ResourceName"); ). 00060 | 00061 | Resource Name: Part Name: 00062 | 00063 | dragPointXTranslatorTranslator - xTranslator.translator 00064 | dragPointXTranslatorTranslatorActive - xTranslator.translatorActive 00065 | dragPointYTranslatorTranslator - yTranslator.translator 00066 | dragPointYTranslatorTranslatorActive - yTranslator.translatorActive 00067 | dragPointZTranslatorTranslator - zTranslator.translator 00068 | dragPointZTranslatorTranslatorActive - zTranslator.translatorActive 00069 | 00070 | dragPointYZTranslatorTranslator - yzTranslator.translator 00071 | dragPointYZTranslatorTranslatorActive - yzTranslator.translatorActive 00072 | dragPointXZTranslatorTranslator - xzTranslator.translator 00073 | dragPointXZTranslatorTranslatorActive - xzTranslator.translatorActive 00074 | dragPointXYTranslatorTranslator - xyTranslator.translator 00075 | dragPointXYTranslatorTranslatorActive - xyTranslator.translatorActive 00076 | 00077 | dragPointXFeedback - xFeedback 00078 | dragPointYFeedback - yFeedback 00079 | dragPointZFeedback - zFeedback 00080 | 00081 | dragPointYZFeedback - yzFeedback 00082 | dragPointXZFeedback - xzFeedback 00083 | dragPointXYFeedback - xyFeedback 00084 | 00085 | Author(s): Paul Isaacs, Howard Look 00086 | 00087 ______________ S I L I C O N G R A P H I C S I N C . ____________ 00088 _______________________________________________________________________ 00089 */ 00090 00091 #ifndef _SO_DRAGPOINT_DRAGGER_ 00092 #define _SO_DRAGPOINT_DRAGGER_ 00093 00094 #include <Inventor/SbLinear.h> 00095 #include <Inventor/SbBox.h> 00096 #include <Inventor/draggers/SoDragger.h> 00097 #include <Inventor/fields/SoSFVec3f.h> 00098 #include <Inventor/sensors/SoSensor.h> 00099 00100 00101 class SoFieldSensor;
