Hi all, I have just started using pyqt4 and decided to make a small thumbnail-viewer to learn how things work.
I would like the thumbnails to be displayed in a grid that automatically change the grid when resized so I use the QListWidget. So far so good - it works fine ...almost... the thumbnails (QIcons) are very small - how do I make them larger? Code is attached. Thanks! Mads
