Hello all,
I'm trying to draw a selection box on top of an existing svg document
and I'm having trouble getting access to the graphic object to
presumably draw on. The larger goal is I'm trying to implement a mouse
drag select function for my application. I got all the mouse listeners
and rect transforms sorted out I just cant get access to something to
draw on. I dont have to modify the DOM for the rect to draw because it
is temporary, all I want to do is find out what elements are in its
bounding box of the rect change some attributes of the elements and
remove the rect when they mouse up.
Any clues for the clueless?
When I get down to ;
SVGGraphics2D g = new SVGGraphics2D(document);
It throws an error
org.apache.batik.svggen.SVGGraphics2DRuntimeException: domFactory should
not be null
