So now the most significant thing that doesn't work that I care about
is tooltip placement. I don't see any way to get that without
modifying Pivot sources. The most straightforward way would seem to
be to modify Component#mapPointToAncestor and add a new Container
method that I can override.
---- Component.java ----
public Point mapPointToAncestor(Container ancestor, int x, int y) {
return mapPointToAncestor(ancestor, new Point(x, y));
}
public Point mapPointToAncestor(Container ancestor, Point location) {
if (location == null) {
throw new IllegalArgumentException();
}
if (ancestor == null) {
throw new IllegalArgumentException("ancestor is null");
}
Component component = this;
if (component != ancestor) {
Container container = parent;
while (container != null) {
location = container.mapChildPointToContainer(component, location);
if (container == ancestor)
break;
component = container;
container = container.getParent();
}
}
return location;
}
---- Container.java ----
public Point mapChildPointToContainer(Component child, Point location) {
return location.translate(child.getX(), child.getY());
}
---- end ----
Unlike the current mapPointToAncestor, this one conses, but maybe it's
not used in any place that cares so much about performance? For
completeness, you'd also need to change mapPointFromAncestor in a
similar way.
I've tested the above, and it does what I want, more or less (the
tooltip isn't scaled, but maybe it's just as well). As a bonus,
ListButton and CalendarButton pop up in the correct place, though also
not scaled (weird in the case of ListButton anyway). But I'm guessing
you'd prefer not to make a change like this so deep in the system only
to allow an incomplete implementation of ScalePane to work. So I
invite other suggestions.
