The dragger's constructor gets the scene graph for 'ResourceName' 00061 | by querying the global dictionary ( SoDB::getByName("ResourceName"); ). 00062 | 00063 | Resource Name: Part Name: 00064 | 00065 | tabPlaneTranslator - translator 00066 | tabPlaneScaleTabMaterial - scaleTabMaterial 00067 | tabPlaneScaleTabHints - scaleTabHints 00068 | 00069 | 00070 | Author(s): Paul Isaacs 00071 | 00072 ______________ S I L I C O N G R A P H I C S I N C . ____________ 00073 _______________________________________________________________________ 00074 */ 00075 00076 #ifndef _SO_TAB_PLANE_DRAGGER_ 00077 #define _SO_TAB_PLANE_DRAGGER_ 00078 00079 #include <Inventor/SbLinear.h> 00080 #include <Inventor/sensors/SoSensor.h> 00081 #include <Inventor/projectors/SbLineProjector.h> 00082 #include <Inventor/projectors/SbPlaneProjector.h> 00083 #include <Inventor/actions/SoCallbackAction.h> 00084 #include <Inventor/draggers/SoDragger.h> 00085 00086 class SoNode; 00087 class SoCoordinate3; 00088 class SoGLRenderAction; 00089 class SoRayPickAction; 00090 class SoFieldSensor; 00091 00094 00170 00171 00172 class INVENTOR_API SoTabPlaneDragger : public SoDragger 00173 { 00175 SO_KIT_HEADER(SoTabPlaneDragger); 00176 00177 SO_KIT_CATALOG_ENTRY_HEADER(planeSwitch); 00178 SO_KIT_CATALOG_ENTRY_HEADER(translator); 00179 SO_KIT_CATALOG_ENTRY_HEADER(scaleTabs); 00180 SO_KIT_CATALOG_ENTRY_HEADER(scaleTabMaterial); 00181 SO_KIT_CATALOG_ENTRY_HEADER(scaleTabHints); 00182 SO_KIT_CATALOG_ENTRY_HEADER(scaleTabMaterialBinding); 00183 SO_KIT_CATALOG_ENTRY_HEADER(scaleTabNormalBinding); 00184 SO_KIT_CATALOG_ENTRY_HEADER(scaleTabNormal); 00185 SO_KIT_CATALOG_ENTRY_HEADER(edgeScaleCoords); 00186 SO_KIT_CATALOG_ENTRY_HEADER(edgeScaleTab0); 00187 SO_KIT_CATALOG_ENTRY_HEADER(edgeScaleTab1); 00188 SO_KIT_CATALOG_ENTRY_HEADER(edgeScaleTab2); 00189 SO_KIT_CATALOG_ENTRY_HEADER(edgeScaleTab3); 00190 SO_KIT_CATALOG_ENTRY_HEADER(cornerScaleCoords); 00191 SO_KIT_CATALOG_ENTRY_HEADER(cornerScaleTab0); 00192 SO_KIT_CATALOG_ENTRY_HEADER(cornerScaleTab1); 00193 SO_KIT_CATALOG_ENTRY_HEADER(cornerScaleTab2); 00194 SO_KIT_CATALOG_ENTRY_HEADER(cornerScaleTab3); 00195 00196 public: 00197 00199 SoTabPlaneDragger(); 00200 00201 SoSFVec3f translation; 00202 SoSFVec3f scaleFactor; 00203 00209 void adjustScaleTabSize(); 00210 00211 SoINTERNAL public: 00212 static void initClass(); 00213 00214 protected: 00215 00216 static void startCB( void *, SoDragger *); 00217 static void motionCB( void *, SoDragger *); 00218 static void finishCB( void *, SoDragger *); 00219 static void metaKeyChangeCB( void *, SoDragger *); 00220 00221 SbLineProjector *lineProj; 00222 SbPlaneProjector *planeProj; 00223 00224 SoFieldSensor *translFieldSensor; 00225 SoFieldSensor *scaleFieldSensor; 00226 static void fieldSensorCB( void *, SoSensor * ); 00227 static void valueChangedCB( void *, SoDragger * ); 00228 00229 virtual void GLRender( SoGLRenderAction *action ); 00230 00231 void dragStart(); 00232 void drag(); 00233 void dragFinish(); 00234 00235 void translateStart(); 00236 void translateDrag(); 00237 00238 void edgeScaleStart(); 00239 void edgeScaleDrag(); 00240 00241 void cornerScaleStart(); 00242 void cornerScaleDrag(); 00243 00244 void scaleUniformStart(); 00245 void scaleUniformDrag(); 00246 00247 SbVec3f worldRestartPt; 00248 int currentScalePatch; 00249 00250 enum State { 00251 INACTIVE, TRANSLATING, EDGE_SCALING, CORNER_SCALING, UNIFORM_SCALING 00252 }; 00253 SbBool shftDown; 00254 00255 State currentState; 00256 State restartState; 00257 int translateDir; 00258 00259 SbVec3f scaleCenter; 00260 00261 SbBool needScaleTabAdjustment; 00262 void reallyAdjustScaleTabSize(SoGLRenderAction *action); 00263 00264 void getXYScreenLengths( SbVec2f &lengths, const SbMatrix &localToScreen, 00265 const SbVec2s &winSize); 00266 00273 virtual SbBool setUpConnections( SbBool onOff, SbBool doItAlways = FALSE ); 00274 00275 virtual void setDefaultOnNonWritingFields(); 00276 00277 virtual ~SoTabPlaneDragger(); 00278 00279 private: 00280 static const char geomBuffer[]; 00281 }; 00282 00283 #endif /* _SO_TAB_PLANE_DRAGGER_ */
