Layout bounds vs. painting bounds - how to avoid movement from effects?

Question

I have a component that I apply a dropshadow effect to when it's hovered over. This causes a visual glitch as the addition of the dropshadow increases the bounds of the component and so I see it shift in the layout as it is moused over.
What is the best pattern to avoid this?
Do I need to override getLayoutBounds and do something fancy?
I want a solution that doesn't require code changes if my stylesheet is changed and the size of the dropshadow changes because of that.

Answer 1

setPickOnBounds(false) did fix my mouse event issues.
But I am left with the odd layout behaviour.
I have a structure like this:
AnchorPane->BorderPane->Pane-> (bunch of this same structure starting with AnchorPane can be nested within - user can position them by dragging)
The AnchorPane can be resized by the user - to set the minimum size (using setMinWidth/Height). If the min size is less than preferred size, the layout engine does the right thing and uses the preferred size. I.e. if I drag the nested content to the lower-right past the min size that was set by the user dragging the corner then the whole structure expands to keep the children contained. This works using either Group or Pane as the center component of my BorderPane (the east and west components are filled with VBoxs that have other stuff in them).
However... when I drag to change the min size of one of the nested AnchorPanes, while it draws that AnchorPane at the correct size, the parent is not resized to take the new size in to account -- UNLESS I move the nested structures of the resized AnchorPane - then I see the parent structure resizing as if it is accommodating only the preferred size of the nested parts, not the actual size of the nested parts as painted and dictated by the min size.
It's hard to describe, I hope I'm communicating it...
Basically it seems that Pane uses preferred size and not the actual size of child nodes when computing its preferred size. The min size of child nodes being greater than the preferred size of the child nodes does not affect the layout of the parent Pane.
