We are pleased to announce the release of the update for QtitanRibbon component 6.7. In this version we added a new RibbonProgressBar control and non-GUI class RibbonProgressOperation, which allows to perform long-time operations in a separate thread and notify the end-user through the RibbonProgressBar about progress. The main feature of RibbonProgressBar is the RibbonProgressBar::setValueSafe(int) method, which is thread-safe. This means you can safely call it from any thread without fear of breaking the GUI. To demonstrate how it works, we created an example Ribbon_DocumentLoader, it is available for C++ and Python (PySide). Additionaly, RibbonProgressBar supports animation. The progress bar shows the increase or decrease of progress smoothly, without twitching.

Another important feature of version 6.7 is support for the Acrylic effect for top-level windows under OS Windows 11. Unfortunately, there is a bug in Windows 10 which does not allow to use this beautiful effect, but under Windows 11 we found a way to initialize it. For Windows 10, we initialize a common blur effect as an alternative that was introduced in Windows 7. The screenshots below show the difference.

Finally, we fixed a bug in customizing actions engine on the quick access bar and another problems. Improved icon rendering for RibbonButton. QtitanRibbon version 6.7 supports Qt6.6.3.
