How to open 2 different window at same time on 2 different monitor?

Qt embedded developer

I have to do poc for opening 2 different window on 2 different monitor from one cpu. How to do this?

I actually don't know

Is it possible to open it at same time? If yes how?

Aim is that one window will show live graph if sensor connected and if not then just show graph without data on first monitor.

And at same time in second monitor second window will allow to select sensor and it also allow to reduce noise in sensor.

So at combined purpose is to check the sensor noise while connect in original product.

How to do it? How qt can help with one exe application
To serve this purpose on 2 separate monitor at same time when start the qt application?

How I can set that window size such that it directly fit into full screen?

mrdebug

Just using a qdialog and the object QApplication::screens() to know how much screens are available, which resolutions they have etc.
The monitor are related at the same machine and same user or two different machines?

same machine same user

Use the following code to list your screens and move your windows accordingly.

QList<QScreen *> screens=QGuiApplication::screens();
for(auto screen : screens)
	{
	qDebug()<< screen->name()<<screen->availableGeometry();
	}

@mpergand will this code open first window in first monitor and second window on second monitor?
