SwingNode not useable on Raspberry PI
The following code needs Swing and doesn't run properly on a raspberry PI even if JavaFX support is enabled.
/**
* update the given tab with the given panel
*
* @param tab
* @param panel
*/
public void updateTab(Tab tab, JPanel panel) {
if (panel != null) {
final SwingNode swingNode = new SwingNode();
swingNode.setContent(panel);
tab.setContent(swingNode);
}
}
