--- Comment #16 from 319513...@outlook.com <319513...@outlook.com> --- I had implement square and row layout by a simple algorithm in QtFlowLayout: https://github.com/cathaysia/QtFlowLayout/tree/43c24711106fd365c76c7ff9b46ab391a126baa3 If you have any interesting, you can just compile it and run ctest for a skim. But I haven't add it to digikamflowplugin. For the reason is I don't know whether I should PreviewLoadThread or not. In fact, I'm prefer using PreviewLoadThread , as you say, it bring more clear codes and more image format's support, I can enjoy the ecosystem of whole digikam. But I can't stand it's preference. I'll upload two gifs to compare the two case, please give it a look. -- You are receiving this mail because: You are watching all bug changes.
