I'm a newbie in swing and I'm trying to create an application and I'm stuck on a problem.
Basically, what I intend is to show a modal dialog saying that the main application is doing something in the background, however, the dialog containing a label and a progress bar, does not shows this content. It presents a blank dialog.
I have created a SSCCE which is in the attached files.
Please, help me out on this.
Thanks in advance for your help :)
