All my Java applets introduced here use Java version not higher than 1.1.5 and thus they work smoothly with absolute majority of existing browsers. Applets, enclosed within resizable frames, are resizable in Microsoft Internet Explorer and America Online browsers.

This is a new version of the FGrid component (formerly FGGrid). It introduces several radical changes and improvements. The most important one is that now the grid is editable. Furthermore, depending on simple settings, each field can be edited with different types of editors. To use the grid classes as is, without subclassing, one the following editors can be assigned by the field properties settings: TextField, TextArea with a single vertical (for a text with word wrapping), TextArea with both scrollbars or Choice (dropdown). The architecture is quite extendable, so it takes writing just a few lines of code (without subclassing of the grid itself) to make the grid using any new type of a field editor.

This is my latest development, and a very sophisticated one. Additionally, you will find there short user guide and description of some visual components I’ve created.

FGTree applet reads an URL of the source XML document from its parameters, reads the document from the server and parses it. The source XML document contains all the information about tree style and structure (colors, fonts, geometry, pictures, labels, URLs, etc). It is possible to specify within applet parameters a name of some JavaScript method, which will handle FGTree events. The user interface of the component is quite interesting. Each expanded folder has narrow vertical bar (Folder Bar) on its left. When mouse pointer is above the Folder Bar, the bottommost panel of the applet shows the folder name. If the tree structure is big enough to be lost there, the user can just point the mouse sequentially on each nested Folder Bar and thus find out the full path. Each folder can be collapsed by clicking on its Folder Bar.

The user interface, provided by the FGLinkBar applet is completely different from the FGTree one (see above), but all other features are pretty much alike. The applet reads an URL of the source XML document from its parameters, reads the document from the server and parses it. The source XML document contains all the information about buttons and drop-down menus (colors, fonts, alignments, geometry, pictures, labels, URLs, etc). It is possible to specify within applet parameters a name of some JavaScript method, which will handle FGLinkBar events.

At first I created Oops image editor as a Windows application (it was interesting for me to create the image transformations algorithms). Recently I’ve turned it to Java applet.

August 10, 2000 I had a presentation at the Orange County Java User Group meeting. Their chairman Mr Ray Tayek called my component a supergrid. Since than I didn’t have a chance to return to this project but I certainly will.

You can find brief description of this project at the following addresses: http://www.ics.uci.edu/~eppstein/junkyard/fractal.html or http://www.ics.uci.edu/~eppstein/junkyard/software.html . This web-site is maintained by professor of mathematics of University of California, Irvine, Mr. Eppstein. The site is one of 4 sites, listed on Yahoo Computational Geometry page. Their links to my applet refer to my former AOL web-page which is not alive any more.

The same applet is hosted by MathsNet http://www.mathsnet.net/js/liveland.html and ScienceU http://www.scienceu.com/library/
