SWT Menus example not working: "Menu must be a drop dow

[tanukitzu]

After installing Designer, I created a new "SWT JFace Java Project" and then created a new class through the menu new->designer->examples->Multi Controls ->Menu.

The example fails to run with the following error:

Exception in thread "main" java.lang.IllegalArgumentException: Menu must be a drop down
at org.eclipse.swt.SWT.error(SWT.java:2677)
at org.eclipse.swt.SWT.error(SWT.java:2616)

at org.eclipse.swt.widgets.Widget.error(Widget.java:376)
at org.eclipse.swt.widgets.MenuItem.setMenu(MenuItem.java:663)
at menusExample.main(menusExample.java:120)

Any help is appreciated.

The was a bug in the Menu example template. You can either change the line...

cascadeItem.setMenu(popupmenu);

to...

cascadeItem.setMenu(cascademenu);

or download the latest v3.0.1 build and create the example again (the template is corrected in 3.0.1).

With those the changes the example compiles and runs, but the menubar doesn't display properly in GTK.

Seems to work fine for me using Eclipse 3.1 M5...

Can you post the exact source for your example so I can compare it to what I have?
