    If you explain exactly what you want to do, maybe I can help. Otherwise there is no other idea.

        I'm not sure but I do not think it's any other way. You can use C ++ for get data and send it back to QML.(emit data)

        If you find another way, I ask you to share.

        Good luck.

          Maybe this is what you want :

          Button.qml

          Rectangle {
              border.color: "black"
              radius:5
              width:60
              height:75
          
              property var clikedX;
              property var clikedY;
          
              signal btnClick()
          
              MouseArea{
                  anchors.fill: parent
                  onClicked: {
                      clikedX = mouseX
                      clikedY = mouseY
                      btnClick()
                  }
              }
          }
          

          Other.qml

          Window {
              visible: true
              width: 640
              height: 480
              //title: qsTr("Hello World")
          
              Button {
                  onBtnClick: {
                      console.log(clikedX)
                      console.log(clikedY)
                      //do something with your clikedX/clikedY
                  }
              }
          }

            @johngod

            Isn't this similar to the following code?

            Button.qml

            
                    onClicked: {
                       clikedX=parent.x
                       clikedY=parent.y
                        callOther.otherX=clikedX
                        callOther.otherY=clikedY
                         }}
            
            }
            
                Other{
                    id:callOther
                }
            }
            

            Does not include all the content in Button.qml?

              Hi @aktay
              It's similar but a bit different, by using the btnClick() signal, I'm decoupling the Buttom.qml from Other.qml, that way Button.qml works as a generic button that can be used anywhere

                I know it. But I think @Titi01 does not want it.

                @Titi01 said in Use a variable in another file:

                If I use

                /    Other{
                        id:callOther
                    }
                

                I have all the contents of Other.qml that appears in Button.qml

                Let's see what happens.

                Thank you for your response.

                  Hello,
                  I have 2 files:
                  -Button.qml
                  -Other.qml

                  I have 2 variable in button.qml (clikedX and clikedY)and I would like to retrieve the value of these variables in other.qml

                  how should I do it?

                  Button.qml:

                  Rectangle {
                      border.color: "black"
                      radius:5
                      width:60
                      height:75
                  
                      property var clikedX;
                      property var clikedY;
                  
                  
                      MouseArea{
                  
                          anchors.fill:parent
                  
                      onClicked: {
                         loader.source="other.qml"
                         clikedX=parent.x
                         clikedY=parent.y
                  
                           }
                  

                  other.qml:

                  I would like here use the value of clikedX and ClikedY (so the value of parent.x and parent.y...)

                  @Titi01 Where do you want to create an object of Button.qml?

                    I create objects of "Button.qml" in the main.qml.
                    But I would like that when I click on this button that clikedX and clikedY contain the value of parent.x and parent.y.
                    Then after you can use the value of clikedX and clikedY in other.qml
                    But I do not create a Button in Other.qml ... @Yashpal @johngod @aktay

                      @Titi01 Hopefully, you are creating an object of Other.qml in main.qml then, accessing clickedX and clickedY should be ease as objects of other.qml and button.qml are siblings. Other than this I'm unable to guess what you want to achieve.
