Maybe you should better use the icons supplied with the system or desktop. I think Qt has a method to get a system icon from the iconset user has.
For GNOME, you could use the stock_lock-broken, stock_lock and stock_lock-ok. Or the generic "error", "warning" and "OK" icons.
Thanks for the suggestion,
I'm thinking about that, yes. That's the QIcon::fromTheme method. It has advantages to use the system theme icons, but also drawbacks. Ie, if Bitcoin looks different everywhere, hard to make documentation.
Also, for Mac and Windows we'll need built-in icons to fall back on.
Which is why I'd really love to be able to load the wallet.dat into gnucash or the KDE equivalent (can't remember).
You mean something like "Export to CSV"? Or do they have some specific format? Would indeed be useful...
