## Detailed Description

The document containing the crystal structure.

Definition at line 80 of file crystaldoc.h.

## Constructor & Destructor Documentation

gcu::CrystalDoc::CrystalDoc | ( | Application * | App | ) |

The constructor of CrystalDoc

virtual gcu::CrystalDoc::~CrystalDoc | ( |  | ) | `[virtual]`

The destructor of CrystalDoc

## Member Function Documentation

void gcu::CrystalDoc::ParseXMLTree | ( | xmlNode * | xml | ) |

Parameters:

  | xml,: | a pointer to the root xmlNode of the xmlDoc containing the definition of the crystal.

Analyses the contents of the XML document and builds the cryatl structure from the data. Typical usage is:

    CrystalDoc* crystal = new CrystalDoc();
    xmlDocPtr doc = xmlParseFile(filename);
    crystal->ParseXMLTree(doc->children);

void gcu::CrystalDoc::Update | ( |  | ) |

This method must be called when a new document is loaded or when the definition of the crystal is changed. It recalculates everything and updates all the views.

CrystalView* gcu::CrystalDoc::GetView | ( |  | ) |

Returns:
  a pointer to the first CrystalView of the document. The view will be created if it does not already exist.

Reimplemented from gcu::GLDocument.

void gcu::CrystalDoc::Draw | ( |  | ) | `[virtual]`

Draws the document using OpenGL primitives.

Implements gcu::GLDocument.

virtual CrystalView* gcu::CrystalDoc::CreateNewView | ( |  | ) | `[virtual]`

Creates a view of the document. This method should be overrided by programs deriving a new view class from CrystalView.

Returns:
  a pointer to the new CrystalView instance.

virtual CrystalAtom* gcu::CrystalDoc::CreateNewAtom | ( |  | ) | `[virtual]`

Creates a new atom. This method should be overrided by programs deriving a new view class from CrystalAtom.

Returns:
  a pointer to the new CrystalAtom instance.

virtual CrystalLine* gcu::CrystalDoc::CreateNewLine | ( |  | ) | `[virtual]`

Creates a new line. This method should be overrided by programs deriving a new view class from CrystalLine.

Returns:
  a pointer to the new CrystalLine instance.

virtual CrystalCleavage* gcu::CrystalDoc::CreateNewCleavage | ( |  | ) | `[virtual]`

Creates a new cleavage. This method should be overrided by programs deriving a new line class from CrystalCleavage

Returns:
  a pointer to the new CrystalCleavage instance.

xmlDocPtr gcu::CrystalDoc::BuildXMLTree | ( |  | ) |

Builds the xmlDoc corresponding to the crystal structure.

Returns:
  a pointer to the XML document.

virtual const char* gcu::CrystalDoc::GetProgramId | ( |  | ) | `[virtual]`

Returns:
  the identity of the program as saved in files in the generator tag. This method should be overrided by programs able to save crystal structures in XML files conforming to gcrystal.dtd. It is used mainly to ensure compatiblity with files created by older versions of the program.

void gcu::CrystalDoc::Init | ( |  | ) | `[protected]`

Initialize a new CrystalDoc instance.

void gcu::CrystalDoc::Reinit | ( |  | ) | `[protected]`

Reinitialize a CrystalDoc instance. Used when loading a file in an already existing document.

virtual bool gcu::CrystalDoc::LoadNewView | ( | xmlNodePtr | node | ) | `[protected, virtual]`

Parameters:

  | node,: | the xmlNode containing the serialized view.

Loads a view from a XML document. This methd must be overrided by applications supporting multiple views.
