Example code for QTableWidget with images

[bruccutler]

I want to have images in some of the columns of my table. I have the added icons, but they are too small. How do I scale the images to fill the cell?

Use QPixmap::scaled. You can choose to keep the aspect ratio.

Thanks. That worked. Now, how do I center the image in the cell?
