Accessing the menu from a ChartPanel?

[Tom Carden]

At the moment I'm using a ChartPanel in a javax.swing.JInternalFrame, and it's working brilliantly. However, I'd like to change the menu from being a JPopupMenu to a JMenuBar on the JInternalFrame. I've pretty much accomplished this like so:

-----------------------------------
ChartPanel chartPanel = new ChartPanel(getMyChart());

JInternalFrame chartFrame = new JInternalFrame("Chart Test");
chartFrame.getContentPane().add(chartPanel);

JMenu chartMenu = new JMenu("Chart Options");
MenuElement[] menuElements = chartPanel.getPopupMenu().getSubElements();
for (int i = 0; i < menuElements.length; i++) {
chartMenu.add((JMenuItem)menuElements);
}
JMenuBar chartMenuBar = new JMenuBar();
chartMenuBar.add(chartMenu);
chartFrame.setJMenuBar(chartMenuBar);

-----------------------------

The menubar of the frame now contains the chart controls as required. The problem is that a small, empty, JPopupMenu remains active upon right click. Is there a way I can get rid of this? Can access to a control menu (built on demand?) be given so that this works even if the menu is turned off using the constructor?

Thanks for reading,

Tom.

You should be able to set the popup menu on the ChartPanel to null, and then nothing will be displayed.

Oh yeah, I didn't think of that (obviously!).

Brilliant software, brilliant support. Thank you.
