MessageBox does not display Close Icon

[majain]

It will be nice if MessageBox shows the Close icon (x) in it's title bar to close itself.

Does anyone know how to show Close icon (x) in the title bar of MessageBox?

It used to exist with mygwt library but couldn't find an easy way with GXT.

Any help is appreciated.

Darell - Do you think you can answer this?

I really like to see Close icon (X) on the messageBox title bar as we normally see it in Windows apps.

Thanks.
