Hello Ralf! Thanks for this. But I think I found the same article inthe english wikipedia. But I didn't see a statistic of usage.I'm not worried about how easyit is to program or on how much eye-candy there is or isn't. I'm just interested in the amount of usage. So you might say, I'm looking for defacto standards. I know, that on Linux there's a lot written in GTK+ and QT. I know, that QT also works on windows. I suppose, that on Mac one of there toolkits is currently preferred. I gather, that they are very much aware of consistency in their application looks. So I'm not even asking, which one is the best, but just which ones are used the most.
