问题 I need to have an observable list of a type that will be displayed in a TableView with one single column, that when selected will display the rest of its information on the right.

问题 I'm brand new to CSS, and trying to make a MWE for a chart in JavaFX. I've been able to make it work in some cases, but my problems pop up when I try to define variables in root.

问题 I'm simulating a compass where I need to display current angular position upon reception of angular data from another source(via network).
