Usage

From source file:org.eclipse.jubula.rc.javafx.tester.adapter.TreeOperationContext.java

@Override
public Rectangle getNodeBounds(final Object node) {
    Rectangle result = EventThreadQueuerJavaFXImpl.invokeAndWait("getNodeBounds", new Callable<Rectangle>() { //$NON-NLS-1$

        public Rectangle call() throws Exception {

                    // we would get old position values
                    tree.layout();
