    When you compile, does it then show the warning id in output ?
    like -Wuninitialized etc

    I need something more than "Strict Equality Comparison" to find the key as
    i only get javascript hits on that term so Im not sure which you actually want to supress.

    Cab you list the actual warning you get ?

    The solution is something like
    QMAKE_CXXFLAGS += -Wno-enum-compare

    but we need to know the actual thing it complains about so we kill the right one :)

      No, It show as line annotations.
      Error code is M126.
      I don't have any problems that I can't compile, but I asked because it bothers me while coding.

        Ah that is the clang code model.
        https://doc.qt.io/qtcreator/creator-clang-codemodel.html

        You can either disable the plugin completely
        https://forum.qt.io/topic/100762/qt-creator-clang-code-model-problems-collection

        Or go to option and c++ / code model and see if you can add remove it.
        (often you can tool tip the warning and it tells what option)

        Just make a copy of current default settings then you can change it.

        Then go look
        https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html

        and see if sounds like the warning.

          I understood well, but I couldn't find description of strict equality comparison in Warning Options.

            Hi
            Can you give me a code snippet that gives that warning ?
            Then maybe I can get hint from that ?

              It's an extreme example,

              property int i
              
                  Component.onCompleted: {
                      i = Math.floor(Math.random() * 10)
                  }
              
                  onClicked: {
                      if( inputText.text == i ){ //M126 is shown here
                          console.log("OK")
                      }
                      else {
                          console.log("NO")
                     }
                  }
              

              I know why it's showing.

                @w-tkm why don't you do a proper comparison, instead of disabling the warnings ?

                if( parseInt(inputText.text) === i )
                //or
                if(inputText.text === i.toString())
                

                or the lazy way:

                inputText.text === "" +i

                  I'm afraid you cannot configure it.

                    You could try to force int conversion:

                    onClicked: {
                            if( parseInt(inputText.text, 10) === i) ){

                            else {

                    Or to disable the warning:

                     onClicked: {
                            // @disable-check M126
                            if( inputText.text == i ){ 
                                console.log("OK")
                            }
                            else {
                                console.log("NO")

                        It seems to there is no setting in the options.

                          Do mean a global disable of this warning?
                          AFAIK, there is no way to do it.
                          But warnings are there to help you the write clean QML code, as QML is a declarative language, it is hard to be sure to write a clean code, so warnings are welcome to highlight not "so clean code" ;)
