      ah...
      wrapping eval() solved this

      ApplicationWindow{ // my app
        id:root
      ...
        property var warnings : "" 
        property int nbr : 0
      ...
      
          Window{// my testing window
          
            TextInput{
                     id:cmd
                           // i want to write  root.warnings = "warn" 
                           //or  root.nbr = 666
            }
             Button{
                        function evaluate(str){eval(str)} // wrap
              onClicked : evaluate(cmd.text) 
             }
          }
      }
      

      however qt creator still rises the warning

      evaluate(cmd.text)

      You want to eval user inputted text?! Are you going to vet that text?

      C++ is a perfectly valid school of magic.

          Sorry, I totally missed that and went to the code. Maybe you can do it from the C++ side? Return the results to the QML side?

              If you want to modify property for some live debugging, have you checked https://www.kdab.com/development-resources/qt-tools/gammaray/ ?

                  @GrecKo how to build it ? My QtQuick project uses Qt 13.0 and mingw73_64
                  there is a Install.txt file in the project it says :

                   // Building on Windows with MinGW:
                  //Make sure you have the path to the MinGW programs in %PATH% first, for example:
                  % set "PATH=c:\MinGW\mingw64\bin;%PATH%"
                  Now build:
                  % mkdir build
                  % cd build
                  % cmake -G "MinGW Makefiles" ..
                  % mingw32-make
                  % mingw32-make install
                  

                  should i use my Qt mingw or a standalone mingw here ?
