How can I get the location of the divider after the user moves it.The divider location can also move when the user resizes the frame. If the size of the split pane is changed the the size of each component added to the split pane may change depending on how the "resize weight" property of the split pane is set, which in turn will cause the divider to change location.
So if you want to know about any change in location of the divider then you should probably be using a PropertyChangeListener (not a MouseListener) and handle the "dividerLocation" property change event. Using this approach you won't need to worry about using the invokeLater() method.
Also, why do you you use the UI to get the divider locaton? The split pane has a method for this.
