Mathador Architecture
Mathador has been implemented in Java according to the Model-View-Controller design architecture.
The model components are completely separated from the view components, this allow a possible reusing of the model components with other view and controller.

Mathador Box Model
The model part of the project is implemented according to the box model.
A box model is a layout technique that adjust the position of some box on the screen. A box is a sort of graphical container for a particular kind of mathematical notation. There are boxes for a large variety of mathematical notations such as numbers, identifiers, fractions, radicals and others.

Mathador Exendible Formats
Mathador use the MathML format for load and save expressions.
Mathador architecture is modular, extensible and reusable with respect to the format supported.
The parser/preprocessor and the serializer provided with the distribution code are only an example of the possible parsers, preprocessors or serializers that can be connected with Mathador. Infact, new versions of these components can be added to Mathador without recompiling the existing code; Mathador can be informed by an appropriate applet parameter include in the HTML code in order to use an other parser (or preprocessor or serializer).
The default parser, preprocessor and serializer implemented in Mathador support only the MathML format, but it is possible to develope a component for any other format like TeX/LaTeX.
Mathador use the MathML dtd of the W3C for validating the documents.

In the default applet (MathApplet is the editor and MathWebViewer is the viewer) you can use the following HTML parameter:

• mathml_dtd, that represent the url of the MathML dtd.
• source_string, that represent the input string in the format accepted by the parser/preprocessor (the default is MathML).
• source_file, is the name of the file (located into the server) that contain the input string (see above).
• preprocessor, is the name of the class that represent the preprocessor component.
• parser, is the name of the class that represent the parser component.
• serializer, is the name of the class that represent the serializer component.

N.B.: In the case that you use the source_string parameter, you must use the single quote ' instead of the double quote " in your code fragment.

For accessing Mathador from Javascript you can use an id attribute in your applet tag and you must call the following methods:

• getCode(), setCode(String code) for getting and setting the input string.
• getFormula() for getting the model of the main box of the formula. To the object returned you can call the following methods:

• setBgcolor(String bgcolor), getBgcolorString() --- hexadecimal color or classic HTML color.
• setColor(String color), getColorString() --- hexadecimal color or classic HTML color.
• setFontSize(int fontSize), getFontSize().
• setFontWeight(String fw), getFontWeightString() --- "bold" or "plain".
• setFontStyle(String fs), getFontStyleString() --- "italic" or "plain".
• and other ....
