问题 Ok so to make a long story short I'm trying to create a sort of chat/message system and need a small bit of assistance. I'm trying to create an arrow on my container as the one shown in the image below. The image is taken off of ControlsFX and from their PopOver window. I CANNOT use their popover widget because it behaves a little wonky with what I'm using it for.

问题 I want to use ControlsFX Notifications class, as JavaFX seems to doesn't offer anything like it (or does it?). For me to use it I want to be able to customize the color of the notification and some other styles. Does anybody have an idea of how I can do that?

问题 I want to port an old swing tool which uses an also old version of JGraph to JavaFX8. However, since JGraph is a Swing-Based library, is thought about replacing it, too. So, is there something equivalent to JGraph, but working with JavaFX8? 回答1: So, is there something equivalent to JGraph, but working with JavaFX8?

问题 I have a small game which has New Game button. There are many variables which need reset when the New Game button is pressed. Is there any method which can easily reload the whole application or any alternative to refresh the scene, stage or variables?
