window

[jacek]

I need a new window, where then I can put in it some widget (button, check...);

Read the FAQ.

And to open another instance of my applications? Can you tell me how to do this so?!

Use QProcess.

mmm...but I need something abou hist to insert in main.ccp:

QApplication a( argc, argv );
QApplication p( argc, argv );
........
return a.exec();

QApplication a( argc, argv );
QApplication p( argc, argv );
........
return a.exec();

To copy to clipboard, switch view to plain text mode 

but appear a message says 'can't have more than one application". Is it possible to do
sothing like this above (without error)?

[jacek]

No, it isn't possible.
