Hi,

In JavaFX 2.2 I used setPrefWidth() on a ListCell in order to avoid horizontal scrollbars. The ListCell then always took the width it needed and if it would grow beyond its boundaries, Labels were displayed with "..." This worked fine!

Now, in JavaFX 8 it doesn't work anymore. I figured out it is because of a BorderPane as part of the graphic.

In JavaFX 2.2 the following code produces "..." for the long item and displays the rest right of it. Therefore the button was always visible.

In JavaFX 8 it produces no scrollbars either, but it also just cuts the long text without "..." and moves the button even more to the right, making it essentially hidden and unreachable for the user.
