busy progress bar without thread ?

[jpn]

First of all, could you finally start using appropriate [code] tags, please? I already sent instructions to you.

Secondly, the "default style" depends on the environment. The following piece of code prints out which style is the default style for you:

qDebug() << app.style()->objectName();

qDebug() << app.style()->objectName();

To copy to clipboard, switch view to plain text mode 

You can try different styles by passing it as a command line argument:

./myapp -style windows

./myapp -style windows

To copy to clipboard, switch view to plain text mode 

You can try different styles like "windows", "plastique", "cleanlooks" etc. Does any of them work?
