An example of HTML code would be this (it's the code for the applet in the left frame):

<applet code="Buttonbar.class" name=buttonbarapplet width=160 height=270>
<param name=normbutton value="mainbutton.gif">

If you would like to display your buttonbar horizontally this is also no problem. You just have to set the "orientation" parameter properly and change width and height.
