Hi guys,
I'm very new to JavaFX and I've been honoured with the task of looking into converting a GUI application from Swing to FX. Scene builder seems like a very nice tool to use, I found a guide JavaFX Scene Builder User Guide: About This User Guide | JavaFX 2 Tutorials and Documentation which is pretty comprehensive but I don't seem to be able to find anywhere how to change the colour of the buttons, screenshot inserted below, any idea?
This application has a menu and it is supposed to open and load a file and interact with the info contained in the file. In any case, I think for now I will look only at the GUI (I know very well that the GUI is the last thing to build, but in this case I was asked to focus on the layout and see how that can be improved with the use of CSS)

thanks
