      Hi and welocome to devnet,

      Which version of Qt Creator are you using ?
      Did you build QWT with the same version of Qt as Qt Creator ?
      Did you deploy the plugin for Qt Creator to be able to found ?

          What does the about box of Qt Creator tell you about the Qt version used to build Qt Creator ? That's important piece, you have to build the plugin using that version of Qt,

              @horizonQt If you want to build a plug-in for QtCreator you have to use same Qt version which was used to build QtCreator. So, build it using Qt 6.3.1

                      @horizonQt Was the designer plug-in build and installed?
                      If so you can debug plug-in issues by setting QT_DEBUG_PLUGINS to 1 before starting QtCreator (in a terminal) - that should give you more information about plug-in loading issues.
