A look on the class files

The applet consists of a set of class files. In the following, the hierarchy of the classes is shown. The different applet versions need the classes shown below from the top to the bottom or from the outer to the inner box.

mHotEqn.class

dHotEqn.class

HotEqn.class

package atp

cHotEqn.class
EqScanner.class
EqToken.class
BoxC.class
ColorMaskFilter.class
SymbolLoader.class

sHotEqn.class

HotEqn.jar

The blue classes are the applet classes, which can be used on the HTML pages. The brown classes are the component classes on which the applets are based. The other classes are HotEqn kernel classes for internal use. The component class cHotEqn is for AWT-based applications while sHotEqn is the Swing-based version.

All classes are packaged together with the font files to the Java archive HotEqn.jar. E.g., if you want to use dHotEqn, you have to add the archive specification in the applet tag:

<APPLET CODE="dHotEqn.class" HEIGHT=40 WIDTH=60 ARCHIVE="HotEqn.jar" ...>

<PARAM ... >
</APPLET>

The archive file can be found in the download section on this page.

Where are the font files

HotEqn uses Java fonts for ASCII code characters and takes the font type specified in the optional applet parameter. Symbols and similar characters are taken from gif files located in the package atp. For each size (18, 14, 12, 10, 8) a separate font file Fontsxx.gif and an associated descriptor file Desxx.gif are used.

The Equation Editor

In order to simplify the development of own pages including mathematics, an equation editor has been developed, which uses the dHotEqn features for editing purposes. Click here to start the Editor in a separate window.

HotEqn Download
