JidePopupMenu not showing scroll buttons

[Mojo]

Hello, I want to use the JidePopupMenu for its scrolling capabilities. My understanding is that if there's a long list of items in the JidePopupMenu then it'll display scroll buttons on the top and bottom of the list. I tried it out with the code below, which contains 50 items in the popup and goes out of the screen, but the scroll buttons don't appear. What am I doing wrong?

Code: Select all

public static void main(String[] args)
{   
    final JFrame d = new JFrame();
    final JidePopupMenu ppm = new JidePopupMenu();
    for (int i = 1; i <= 50; i++)
    {
        ppm.add(new JMenuItem("Option " + i));
    }

    d.addMouseListener(new MouseAdapter()
    {
        public void mouseClicked(MouseEvent e)
        {
            ppm.show(d, e.getX(), e.getY());
        }
    });
    d.setPreferredSize(new Dimension(200,100));
    d.setVisible(true);
    d.pack();
}

I don't know why but it does work for me.

Thanks,

I'm using IntelliJ and I moved the "jide-oss-2.2.4.jar" up in my dependencies hierarchy and then it worked fine. Not sure why...maybe it was conflicting with another version of JidePopupMenu in another jar. Oh well, it works.

I am using JideMenu.setPopupMenuCustomizer

considering the number of items of the customized menu, there is too many to fit on the screen, however the popup menu does not show scroll buttons.

additionaly, the customize paramater takes a "JPopupMenu" instead of a JidePopupMenu, which has the scrolling interface. I casted it to JidePopupMenu, and got exception..

Code: Select all

myMenu.setPopupMenuCustomizer(new JideMenu.PopupMenuCustomizer() {
         public void customize(JPopupMenu menu) {
//try to cast to see if its really a JidePopupMenu
            JidePopupMenu mnu = (JidePopupMenu)menu;

JideMenu which extends JMenu uses JPopupMenu which doesn't have the scrolling feature. If you look at JMenu code (see below), I am not sure how to intercept it to create JidePopupMenu. The method is private and the popupMenu field is not assignable from outside.

Code: Select all

    private void ensurePopupMenuCreated() {
        if (popupMenu == null) {           
            final JMenu thisMenu = this;
            this.popupMenu = new JPopupMenu();
            popupMenu.setInvoker(this);
            popupListener = createWinListener(popupMenu);
        }
    }

See also this thread on java.net. It points to a RFE in the Sun bug parade open since 2002.

You could maybe hack it by overriding createWinListener and reflection.[/url]
