    Often yes you can.

      @w-tkm

      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

                      You could try to force int conversion:

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

                              else {
                                  console.log("NO")
                             }
                          }
                      

                      Or to disable the warning:

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

                          Thanks. I did it.
                          It seems to there is no setting in the options.

                            Thanks. I did it.
                            It seems to there is no setting in the options.

                            @w-tkm said in How to disable the Strict Equality Comparison warning:

                            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" ;)

                            It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)
