Detailed Description

These are parsing functions for TEXT_EVENT

  Example for useing TEXT_EVENTS:
  ------------------------------------------
  static int slotTextEvent(PARAM *p, int id, DATA *d, const char *text)
  {
    if(p == NULL || id == 0 || d == NULL || text == NULL) return -1;
    float x,y,w,h;
    float m11,m12,m21,m22,det,dx,dy;
    switch(textEventType(text))
    {
      case PLAIN_TEXT_EVENT:
        printf("plain\n");
        break;
      case WIDGET_GEOMETRY:
        int X,Y,W,H;
        getGeometry(text,&X,&Y,&W,&H);
        printf("geometry(%d)=%d,%d,%d,%d\n",id,X,Y,W,H);
        break;
      case PARENT_WIDGET_ID:
        int PID;
        getParentWidgetId(text,&PID);
        printf("parent(%d)=%d\n",id,PID);
        break;
      case SVG_LEFT_BUTTON_PRESSED:
        printf("left pressed\n");
        printf("objectname=%s\n",svgObjectName(text));
        break;
      case SVG_MIDDLE_BUTTON_PRESSED:
        printf("middle pressed\n");
        printf("objectname=%s\n",svgObjectName(text));
        break;
      case SVG_RIGHT_BUTTON_PRESSED:
        printf("right pressed\n");
        printf("objectname=%s\n",svgObjectName(text));
        break;
      case SVG_LEFT_BUTTON_RELEASED:
        printf("left released\n");
        printf("objectname=%s\n",svgObjectName(text));
        break;
      case SVG_MIDDLE_BUTTON_RELEASED:
        printf("middle released\n");
        printf("objectname=%s\n",svgObjectName(text));
        break;
      case SVG_RIGHT_BUTTON_RELEASED:
        printf("right released\n");
        break;
      case SVG_BOUNDS_ON_ELEMENT:
        getSvgBoundsOnElement(text, &x, &y, &w, &h);
        printf("bounds object=%s xywh=%f,%f,%f,%f\n",svgObjectName(text),x,y,w,h);
        break;
      case SVG_MATRIX_FOR_ELEMENT:
        getSvgMatrixForElement(text, &m11, &m12, &m21, &m22, &det, &dx, &dy);
        printf("matrix object=%s m=%f,%f,%f,%f det=%f dx=%f dy=%f\n",svgObjectName(text),
                                 m11,m12,m21,m22,det,dx,dy);
        break;
      default:
        printf("default\n");
        break;
