Well let me see if I can be clearer. Maybe I'm doing this wrong. In my application, I have a glass pane attached to a JFrame (because you can't attach a glass pane directly to a JSVGCanvas). When I'm drawing shapes to the canvas, I draw the "ghosted line" or "outline" as the user drags the mouse, then render the shape to the JSVGCanvas when the user releases the mouse. Since the 0, 0 of the glass pane is the upper-left corner of the application (JFrame), I have to translate by +x and +y where +x is the x of the JSVGCanvas and +y is the y of the JSVGCanvas plus the height of the JMenuBar. Now when I draw to the JSVGCanvas, the glass pane drawing "lines up" with the JSVGCanvas. I've been doing drawing operations like this for a couple months, but it's always felt like a hack.
Yesterday's case was the reverse. I wanted to click on a rendered SVG element and draw its bounding box to the glass pane, taking the above-mentioned offset AND the view box transform of the JSVGCanvas into account.

Why do you need the screen coords of anything? getScreenCTM will map things to the JSVGCanvas's coordinate system (0,0 should be the upper left of the JSVGCanvas). Since I use this to map the clientX/Y into the SVG content all the time with the screen CTM I'm fairly certain that it is correct. > We got similar problem when develop our Sketsa SVG Editor, we solve the > problem by create using Java shape instead of SVG shape to mimic the SVG > shape to be edited.
