QLabel to display an image and preserve the aspect ratio

[psih128]

At the time of scaling the image. You can use these options:

Qt::KeepAspectRatio
Qt::KeepAspectRatioByExpanding

Qt::KeepAspectRatio
Qt::KeepAspectRatioByExpanding

To copy to clipboard, switch view to plain text mode 

Whatever suits your requirement.

So you propose to create a custom widget, re-implement paintEvent and draw a properly scaled image, right?

Is there a way to do that via Designer without writing code - this is what I was thinking about.
