The only one which "might" look the same is Qt5 Default and Qt6 Basic (same but renamed). But otherwise, no. You may be better to make a custom style defined for your specific use case so you can be confident in your assumptions. However, doing that itself has a different approach in Qt5 and Qt6. Whenever I build new styles (and I have made a lot over the years) I always start from Basic and build upwards as it is the vanilla and least complex base point to understand how the templates work. Which, have also changed between Qt5 and Qt6, so you may even find yourself basically having two very distinct versions of your same style - and you still may have odd quirks between them. Here's a good one - ComboBox and it's currentValue and currentText properties and associated role properties. You should try doing that in Qt5. I did, and succeeded, but it wasn't nice. So even having to hand adjust your style implementation to look the same will still be at the mercy of the template differences - and your application logic will also be dependent on those APIs as well. I appreciate that you have a tough job!

I found the Universal style to be more portable and less taxing. Universal also works better on software rendering and I favor it when writing desktop apps. For Qt5 there is also community maintained dark CSS styles which works great in mixed QWidgets/QtQuick applications when using the Universal dark theme. -- Frank _______________________________________________ Interest mailing list Interest@qt-project.org https://urldefense.com/v3/__https://lists.qt-project.org/listinfo/interest__;!!Nbma_1s!rLJveX92WbfP9QwEOcxaB3V0vIKDZDl8B8fpgbhXkjKqzsbGZJqvvOTYt1uq2HhEQnKhGoqMqo8X4xwfng$ Confidentiality Notice: This message (including attachments) is a private communication solely for use of the intended recipient(s).
