[macOS] QMacToolBar doesn't support new styles in macOS Big Sur

    XMLWordPrintable

Details

    • macOS

    Description

      QMacToolBar buttons are misplaced and look broken in a Qt app

      Strangely enough: when using XCode 11.3, it's fine. See screenshots

      Update: the reason is new NSWindowToolbarStyle
      By default it uses NSWindowToolbarStyleAutomatic whilst most users expect traditional approach.
      Just wrote a quick workaround class for it to avoid modifying Qt. Do recommend though adding this enum/get/set to the QMacToolbar class.
