I'm going the coordinates of my cursor from Java.AWT.MouseInfo and I need to convert it to the coordinate relative to a ScrollPane's viewport. I'm trying to have the scrollpane's scrollbar positions center on where the mouse was when zooming in/out.
viewScroll is a ScrollPane. zoomGroup is a Group containing an imageView that is scaled (zooming). When scaled the method repositions the scrollbars where it was before the scale. I want to reposition the scrollbars where the mouse was at the time of zooming.
protected void zoom(double scaleValue) {
p = MouseInfo.getPointerInfo().getLocation();
double Y = p.getX();
double X = p.getY();
double scrollH = viewScroll.getHvalue();
double scrollV = viewScroll.getVvalue();
zoomGroup.setScaleX(scaleValue);
zoomGroup.setScaleY(scaleValue);
viewScroll.setHvalue(Y);
viewScroll.setVvalue(X);
}
