// After loading...
ISvgDocument doc = svgPictureBox.Window.Document;
doc.RootElement.AddEventListener("click", new
EventListener(ClickHandler), false);
doc.RootElement.AddEventListener("mousedown", new
EventListener(MouseDownHandler), false);
doc.RootElement.AddEventListener("mouseup", new
EventListener(MouseUpHandler), false);
doc.RootElement.AddEventListener("mousemove", new
EventListener(MouseMoveHandler), false);
doc.RootElement.AddEventListener("mouseover", new
EventListener(MouseOverHandler), false);
doc.RootElement.AddEventListener("mouseout", new
EventListener(MouseOutHandler), false);
etc....
public void MouseOverHandler(IEvent e)
{
SvgElement aGraphic = null;
if (e.Target is SvgElement)
aGraphic = ((SvgElement)e.Target);
else if (e.Target is SvgElementInstance)
aGraphic =
(SvgElement)((SvgElementInstance)e.Target).CorrespondingUseElement;
aGraphic.SetAttribute("stroke", "cyan");
svgPictureBox1.Render();
}
And so on... keep in mind, this only works from the CVS version,
re-rendering is not optimized, and if you are planning on using GetCTM,
GetTransformToElement, GetScreenCTM or the like, wait. I will be
finished in a couple more days I think...
Cheers,
