actually, I am already sticked to this event. but now, I want the element to
follow the pointer when left button pressed:
mask.addEventListener("mousemove",
new org.w3c.dom.events.EventListener() {
public void handleEvent(Event evt) {
MouseEvent mouseEvent = (MouseEvent) evt;
if (mouseEvent.getButton() == 1) {
//HELP ME
}
but the HELP ME part is still confused to me. I found in the batik dist 1.7
a sample named sydney.svg where some javascript tries to do the same (moving
images on click and drag events). In squiggle, the scale is not preserved,
but the image moves under the pointer. In the code, they use this:
// handle the current zoom and pan
var trans = document.documentElement.currentTranslate;
var scale = document.documentElement.currentScale;
I could not find such method/member to get that. how can I do?
