Menus on MAC problem. URGENT! [message #447887]

We've got an SWT-application with menus and want it to run on MacOS
(outside of Eclipse!). Currently it runs perfectly on Windows and Linux,
but the main-menu doesnŽt work on MacOS.

Can someone please tell us exactly, whatŽs important in this scenario?
- what libraries and configurations do we need?
- Do we have to patch the code or should it run on MacOS without
modification?

A working solution within the next days will be rewarded!

Thanks,
Oliver

How exactly? Doesn't it show up? Doesn't it do what you'd exept if you
click on a menu entry?
Please describe your problem, maybe with a link to a screenshot.

If you tell exactly what's the problem?

I am not very familar with SWT, but I guess that noone can give you a
good advice without knowing what the problem is.

Dear Tomas,

thanks for your quick feedback!

I think, first of all we need to know how a working configuration would
look like on a Mac (Version 10.3.7) before we try to analyze the current
behaviour. I think it must be something "obvious" for SWT users on a MAC,
and weŽre just not very familiar with a MAC.

Here is our configuration:
MacOS 10.3.7
SWT version 3101

When we start the application with the java command, it doesnŽt react to
user-input.
When we start the application with the java_swt command, it runs, but when
the main menu is selected, the VM crashes with a bus error.

Ideas?
Oliver

Enter a problem report with the stack trace. Can you make a simple SWT
program that crashes as well? If so, append that to the bug report. Give
us more information to work with. Have you tried a nightly download of SWT
to see if the problem has already been fixed? For example, I remember that
the Mac used to GP instantly if you attempted to pull down a menu that had
no submenu.

Hi Steve,

thanks for your feedback :-)

> Enter a problem report with the stack trace.
We have no stack trace, since the VM crashes.

Oh, very interesting! I will try it and post the result...

Ok, the VM crashes only with an empty menu and with swt-version<=3101.
swt-version 3116 doesnŽt crash any more :-)
but empty menu-items canŽt be selected.

I changed our application now to avoid empty menus ;-)

Many thanks for helping!

Here is a code-snippet that produces the problem:
------------------------------------------------------------
import java.util.Date;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;

/**
* Problem snippet for Menus on MacOS
* version 3101: VM-Crash
* version 3116: empty menu-item canŽt be selected
*/
public class testapp {

public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell();
shell.setText("SWT Application");

Menu menubar=new Menu(shell, SWT.BAR);
shell.setMenuBar(menubar);
{
final MenuItem menuItem = new MenuItem(menubar, SWT.NONE);
menuItem.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent arg0) {
shell.setText(new Date().toString());
}
});
menuItem.setText("BadEntry");
}

shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
}
}

I don't really understand what "the main-menu doesn't work on MacOS" means,
but it sounds that you are trying to run an SWT application from the command
line by using "/usr/bin/java". This does not work on MacOS X.
Please, read this SWT FAQ entry:

Please enter a problem report for "empty menu-items can't be selected".
