Hi, I am new to this list and trying to get up to speed on batik. I am currently attempting to develop CAD like software and would appreciate some guidance / pointers.
Currently I start with a fresh DOM, and set up a dynamic bridge to a GVT. Then I allow the user to add elements to the dom with the mouse like dragging a rectangle onto the screen. I paint the rectangle whilst the user is drawing then when the mouse is released I add it to the DOM like so: Document doc = model.getDocument(); // Create the rectangle. Element elem = doc.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI, "rect"); elem.setAttributeNS(null, "x", DoubleFormat.format(x)); elem .setAttributeNS(null, "y", DoubleFormat.format(y)); elem.setAttributeNS(null, "width", DoubleFormat.format(w)); elem.setAttributeNS(null, "height", DoubleFormat.format(h)); elem.setAttributeNS(null, "style", "fill:none;stroke:#000000;"); doc.getDocumentElement().appendChild(elem); This works, and when I repaint the GVT the rectangle is there. Now I am trying to detect mouseover and allow modification like select, drag, rotate, delete etc.... I have 2 key questions at this stage: 1. Is there any way to detect mouse over with some tolerance, i.e. I have mouse over code that will detect if the mouse is on the rectangle above, however this rectangle has a 1 px line width, and it is very hard to keep the mouse on the rectangle. Ideally I would like to detect is the mouse is within 3px of the rectangle and trigger an event then. The code that I am currently using is: GraphicsNode gn = model.getGVTRoot().nodeHitAt(p); 2. Is there any way to maintain a link between a DOM Element or GVT Node and a custom object? What I am trying to do is have my own object representing the rectangle that allows for a properties panel where when the Element is selected the user can see height, width etc and modify these properties. Is there a better way to do this? Thanks in advance for your assistance. -- View this message in context: http://www.nabble.com/Mouse-Detection---GVT-Node-Reference-tp18804429p18804429.html Sent from the Batik - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
