The dragger's constructor gets the scene graph for 'ResourceName' 00062 | by querying the global dictionary ( SoDB::getByName("ResourceName"); ). 00063 | 00064 | Resource Name: Part Name: 00065 | 00066 | pointLightOverallMaterial - material 00067 | 00068 | pointLightTranslatorLineTranslator - 00069 | - translator.xTranslator.translator 00070 | - translator.yTranslator.translator 00071 | - translator.zTranslator.translator 00072 | pointLightTranslatorLineTranslatorActive - 00073 | - translator.xTranslator.translatorActive 00074 | - translator.yTranslator.translatorActive 00075 | - translator.zTranslator.translatorActive 00076 | 00077 | pointLightTranslatorPlaneTranslator - 00078 | - translator.yzTranslator.translator 00079 | - translator.xzTranslator.translator 00080 | - translator.xyTranslator.translator 00081 | pointLightTranslatorPlaneTranslatorActive - 00082 | - translator.yzTranslator.translatorActive 00083 | - translator.xzTranslator.translatorActive 00084 | - translator.xyTranslator.translatorActive 00085 | 00086 | 00087 | Author(s): Paul Isaacs, Howard Look 00088 | 00089 ______________ S I L I C O N G R A P H I C S I N C . ____________ 00090 _______________________________________________________________________ 00091 */ 00092 00093 #ifndef _SO_POINT_LIGHT_DRAGGER_ 00094 #define _SO_POINT_LIGHT_DRAGGER_ 00095 00096 #include <Inventor/SbLinear.h> 00097 #include <Inventor/draggers/SoDragger.h> 00098 #include <Inventor/fields/SoSFVec3f.h> 00099 #include <Inventor/sensors/SoSensor.h> 00100 00101 class SoFieldSensor; 00102 00105 00181 00182 00183 class INVENTOR_API SoPointLightDragger : public SoDragger 00184 { 00185 SO_KIT_HEADER(SoPointLightDragger); 00186 00190 SO_KIT_CATALOG_ENTRY_HEADER(material); 00191 00192 SO_KIT_CATALOG_ENTRY_HEADER(translator); 00193 00194 public: 00196 SoPointLightDragger(); 00197 00198 SoSFVec3f translation; 00199 00200 SoINTERNAL public: 00201 static void initClass(); 00202 00203 protected: 00204 00205 SoFieldSensor *fieldSensor; 00206 static void fieldSensorCB( void *, SoSensor * ); 00207 static void valueChangedCB( void *, SoDragger * ); 00208 00217 virtual SbBool setUpConnections( SbBool onOff, SbBool doItAlways = FALSE ); 00218 00219 virtual void setDefaultOnNonWritingFields(); 00220 00221 virtual ~SoPointLightDragger(); 00222 00223 private: 00224 00225 static const char geomBuffer[]; 00226 }; 00227 00228 #endif /* _SO_POINT_LIGHT_DRAGGER_ */
