JSVGComponent vs JSVGCanvas

[rick bolkey <bo...@seas.upenn.edu>]

Newbie question, well, just a clarification:

I looked through the archive, but I couldn't find a satisfiable definition of
the two classes, JSVGComponent and JSVGCanvas.  From what I can gather from the
javadoc, JSVGComponent is the swing component for displaying svg images, and
the JSVGCanvas simply adds interaction (zoom, pan, etc) to the JSVGComponent.

So, if I just wanted to display an svg images without user interaction, I
could just use JSVGComponent ... I'm asking this because all the examples use
the canvas.  Is the canvas the prefered component?  Just want to know when what
is appropriate.

thanks for the help,
rick

The SVGCanvas is a subclass of the SVGComponent. Basically, the SVGCanvas has 
been created to ease the use of the SVGComponent. Here are the key points:

1. The SVGCanvas provide some utility method (with predefined bindings) to 
add intereactors such as zoom, pan and rotate.

2. The SVGCanvas has a BeanInfo that indicates to the beanbox or IDE what the 
icon is...

3. The SVGCanvas is conformed to the JavaBean spec. It means that the methods 
fire property events...

In your own application, you can use both the same way - it's just up to you. 
SVGCanvas does not provide additional functionality - just a bean API.
