XMLMember SciFigs::HistogramLayer::xml_member ( XML_MEMBER_ARGS ) [protected, virtual]

Re-implement this function to offer XML restore (children and properties) support to your class.

From tag and map (with contains the attibute value) return a unique identifier under the format of a XMLMember. XMLMember is initialized with 3 types of contructors:

An integer: id number of a property
A XMLClass * : a child of this object identified by tag
Default constructor: error, unknow child or property

Map of attributes can be inspected in this way (can be achived also in xml_setProperty()):

    static const QString tmp("childrenName");
    XMLRestoreAttributeIterator it=map.find(tmp);
    if(it!=map.end()) {
      // found attribute "childrenName"
    }

If the map of attributes is not used:

    Q_UNUSED(attributes);
    if(tag=="x1") return XMLMember(0);
    else if(tag=="y1") return XMLMember(1);
    else if(tag=="x2") return XMLMember(2);
    else if(tag=="y2") return XMLMember(3);
    else return XMLMember(XMLMember::Unknown);

Arithmetic operations + and - apply to XMLMember to avoid confusion of property id numbers between inherited objects. Offset 3 corresponds to the number of properties defined in this object.

    if(tag=="anInteger") return XMLMember(0);
    else if(tag=="aString") return XMLMember(1);
    else if(tag=="aDouble") return XMLMember(2);
    return AbstractLine::xml_member(tag, attributes, context)+3;

For the arguments of this function use Macro XML_MEMBER_ARGS.

Reimplemented from SciFigs::GraphContentLayer.

  {

  }

bool SciFigs::HistogramLayer::xml_setProperty ( XML_SETPROPERTY_ARGS ) [protected, virtual]

Re-implement this function to offer XML restore properties support to your class.

From memberID set the corresponding property with value content. The map of attributes is given as a supplementary information (not useful in all cases).

For a general case:

  Q_UNUSED(attributes);
  double val=content.toDouble();
  switch (memberID) {
  case 0:
    _x1=val;
    return true;
  case 1:
    _y1=val;
    return true;
  case 2:
    _x2=val;
    return true;
  case 3:
    _y2=val;
    return true;
  default:
    return false;
  }

For classes inheriting other classes (see also xml_member())

  switch (memberID) {
  case 0:
    _anInteger=content.toString();
    return true;
  case 1:
    _aString=content.toInt();
    return true;
  case 2:
    _aDouble=content.toDouble();
    return true;
  default:
    return AbstractLine::xml_setProperty(memberID-3, map, content);
