Components
At the moment you will find only a small part of my projects here. I'm doing my best
to publish everything, but some of the projects still need some work, which basically means
I need to write javadoc, unit tests and other documentation for it. I will however try to update this
site regularly with new projects until the entire backlog (23 projects) is gone.
CoffeeBreak is an on-line newsreader that supports most common encodings for attachments. The current
version is a fully functional beta supporting multiple servers, identities and parallel connections. It also
has features for posting multiple files and for downloading the content of nzb-documents.
SquelerDDL is a convenient way to generate SQL Data Definition statements for different databases from the information obtained from meta data.
THex is a hex editor, or binary file editor component with which files and streams can be displayed. The THex component was originally
defined for the Squealer project to look at Blob data in a database. While I need to spend some time analysing different binary files I
needed an editor as an application that could run on all platforms and supports multiple open documents and this might be usefull to others as well.
So I created 
THexeditor as a normal java application.
Library containing extension on default Swing functionality
MaskedField: An implementation of JTextField which displays numbers, dates and textfield with
a specific format
ExtButtonGroup: an implementation of ButtonGroup which allows only one button
to be focus owner and switch between buttons with left/right/up/down.
ScrollablePanel: A Panel which allows for multiple panels added to this to be scrollable
and selectable (with SelectablePanel interface) and which handles scroll intervals correctly
Form, FormAction and EasyForm: panels and interfaces to add default Ok/Apply/Undo/Close buttons
to a Form in a GUI. EasyForm is a set of methods to create a Form quickly, but will leave the
handling of data to the developer.
Library containing Panes to use as dialog extending default Swing functionality
ConnectionPane: Add, removed, edit connection information to databases
and select a JDBC connection for use in your application
AboutPane: A small Pane to give information about the application, such
as version, author, logo, contributors and licensing information.
CalendarPane: Select a date from a Calendar
EditorPane: A simple wrapper around JEditorPane to show text which is
too long to enter into a normal field.
FontChooserPane: Let a user select a Font, size and style from the Fonts available to Java.
PreferencePane: Pane that makes properties for an application into options people can
edit personally. It will take the properties file and either predicts or has been told which
kind of editing option should be supplied for a key.
TwelBox is a collection of functionality that only has a basis
in that I found most projects I have done needed. From some
basic String, Date and Locale manipulation to a standard for
dealing with arguments passing to an application to a very small
and configurable Logger. Also some small implementation changes
to the default Collections provide by Java. The jar file should never grow beyond 32Kb, while it
should never be considered a barrier for including it in an
application.
This is by far the smallest component I made and does one simple thing: It overwrites java.util.ResourceBundle to get the
internationalisation information from a data source instead of a properties file or class. Having written Java applications
that extensively used a database, I did not find it very helpful getting my resources from another source. It surprised me
that there is hardly any performance loss noticeable getting resources from the database
@test is a very small application to show the contents of a Manifest file from inside a jar.
This component is a convenient way for writing java class files from another
java application. It takes care of basic things like formatting, imports, ordering
and has methods to easily methods, innerclasses and such in the javafile.
DataC is just a bunch of interfaces and abstract classes, which don't look very exciting. Their job is defining
a standard Data Modification interface for use in applications. The purpose in design was to have my applications
deal with the data objects only and not bother about how, why or when these data objects where actually stored.
Sql2Class is a simple console application to generate data classes (beans) and data control classes (for use with DataC)
from a JDBC source
