I need to present a dialog when interacting with some of the JavaFX controls. Since a JavaFX Dialog doesn't work properly without a JavaFX Window, I need to continue to use a JOptionPane or JDialog. The current Swing code doesn't have a reference to the parent JFrame. It just uses the control that is associated with the action that triggered the need for a dialog/JOptionPane as the parent. E.g. I press a JButton and a JOptionPane appears. The JOptionPane knows about the button and can use that as the parent component.
Now I have a JavaFX Button… but no path to a reasonable parent for the JOptionPane.
