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
