Setting up to code
You will need the Smartboard java API. Once you have installed this, copy the RegistrationUtils.dll file -
found in SMARTBoardSDK/Java/lib directory to the C:/j2sdk1.4.1_02/jre/bin directory. If the version of java you have installed
does not have a jre directory, copy the .dll into the bin directory.
Code SamplesThe sample that can be found in the SMARTBoard/Java/samples/scribble directory gives you an example of
creating an application that will interface with the Smartboard. It is fairly basic, only allowing you to draw onto the screen. Listed below are
2 examples of interacting with the Smartboard, the CirclePanel and LineDrawPanel files mentioned can be found in the SmartboardSamples.zip. Also
in the .zip file is a SmartboardAPITester class that allows you to test events on the Smartboard.
Running the Board in Projected Mode
This means that you have the computer screen projected onto the Smartboard which allows you to interact with programs on your computer. The
following piece of code opens a window that allows you to move a circle using the Smartboard tools. As written in the comments of the code
you can substitute the CirclePanel for a LineDrawPanel which allows you to draw in the frame.

/**
* A demo for how to register a listener with the smartboard so that you can
* be notified when the board is touched.
*
* This demo is for when the board is in projected mode.
*
* Right now the demo uses the CirclePanel to react to board movement.
* This is a really simple panel that just allows you to move a circle.
* You might want to try changing it so it uses the LineDrawJPanel instead for
* drawing. To do this, change the line:
*
* CirclePanel panel = new CirclePanel();
*
* to
*
* LineDrawJPanel panel = new LineDrawJPanel();
*
* Instead of a "moveCircle" method, the LineDrawJPanel has a "draw" method
* for drawing. So, also change the line
*
* panel.moveCircle(x, y);
*
* to
*
* panel.draw(x, y);

Running the Board in Non-Projected Mode
This means that the SmartBoard is not projected upon and operates as if a whiteboard. As written in the comments of the code
you can substitute the CirclePanel for a LineDrawPanel which allows you to draw in the frame.
