svg - Graphics Editor - How to manipulate screen objects?
I am in the process of developing a Graphics Editor and trying to find the
best way to
detect mouse events on the screen.
I need to implement functions such as:
Select, Move, Add, Delete, screen objects such as lines, circles etc.
1) Where can I put my Mouse listener (which object).
2) Is the best way to display from an svg file and then use 2D to manipulate
(Select, Move etc)
or is it better to go via DOM and manipulate the DOM tree.
This is not a Web application and will be running on Win2K.
I appreciate any help and suggestions you may have for me.. example source
code?
Regards

I'm a little confused here - are you talking about drawing in a browser, or
a standalone Java app?

I would recommend to use the SVG DOM for your manipulation.
The SVG DOM is our model and the repaint will work properly if you are using
the DOM to manipulate your SVG content.
For MouseEvent, use a regular DOM EventListener. In an authoring tool
context, the capture phase might be really useful (provide a way to override
the user behavior defined in the SVG document you are currently editing).
