For Qt 6, check for any updates to your application's target platform.Ī Clazy-based tool is available to facilitate porting from Qt 5 to Qt 6: Porting C++ Applications to Qt 6 using Clazy checks. You can use platform integration APIs to implement native behavior that is not provided by Qt. There is better integration with the native APIs on target platforms in Qt 6. In that case, set the rounding policy to Round to restore Qt 5 behavior. Applications that use Qt Widgets may encounter graphical glitches at non-integer scale factors, for example on Windows with a display configured for 175%. Qt 6 changes the default scale factor rounding policy from Qt::HighDpiScaleFactorRoundingPolicy::Round to Qt::HighDpiScaleFactorRoundingPolicy::PassThrough in order to track operating system DPI settings accurately. Applications only need to provide high-resolution assets, such as images and icons. Qt 6 supports high-DPI displays on all platforms, and will automatically account for the display resolution when using higher level APIs such as Qt Widgets or Qt Quick. Changes to Qt Quick - changes to Qt Quick graphics that may affect Qt 5 applications.The graphical backend for Qt Widgets applications are unchanged from Qt 5. It is still possible to use OpenGL calls in Qt applications, but the OpenGL APIs are moved to the Qt OpenGL module. OpenGL is no longer guaranteed as default on target platforms and you should check that your graphics code is still creating the same effects you want. QML applications have a new graphical backend, which you should test for regressions. Changes to Qt Modules in Qt 6 - list of changes per Qt module.In future Qt 6 releases, new or previous modules may be added. In some cases, APIs from a deprecated module are available in another module. Add_compile_definitions(QT_DISABLE_DEPRECATED_UP_TO = 0x050F00)Ī goal for the Qt 6 release is to maintain a streamlined framework which means the removal of some Qt 5 modules in Qt 6.
