No, its just a window.
Nothing in Qt will let you drag anything out from a mainwindow and it becomes process on its own.

That you need to hand code if you want that.

You would use QProcess to start a new instance of your application and instruct it which
"thing" to open as current.

First of all, thank you.

I want to start the process by QProcess in my interface display
My program can manage the process.

@LeeDaShen
You are welcome.

Give you all you need to start stop the process(es).

You will need to give it arguments when you start it, so it can start up with the "data" you torn
off.

You could use
http://doc.qt.io/qt-5/qdockwidget.html#topLevelChanged
Signal to know when user made it float.
Then you would hide/remove it and start your app again (second time)
with QProcess to get a new process running.

Some parameters must be restarted to not conflict, like cookie

mrjj

@LeeDaShen
Well you need to handle that in main.

You can use
QCoreApplication::arguments().at(1) (2,3,4,5)

to read paramters. There are also
QCommandLineParser for more features.
