Create button to counting

[isan]

I'm new in QML ,I have 3 buttons that should count to 3,2,1 when clicked on and then each of them has its own functions to call
And I want, for example, when the first button was selected and the counting started
If the second button is selected too, the first button will be unchecked and stop counting and the second will operate and start counting but I don't know how to do this!

import QtQuick 2.9
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.3

Button {
    id: button
    checkable: true
   // font.pixelSize: fontSizeExtraSmall
    leftPadding: 4
    rightPadding: 4
    topPadding: 12
    bottomPadding: 12
    implicitWidth: 90
    implicitHeight: 90

    icon.name: "placeholder"
    icon.width: 44
    icon.height: 44
    display: Button.TextUnderIcon


    onClicked: Text{
        id: name
            property int cnt: 3
            text:cnt
        function decrementCnt(){
            if (cnt>0)
            cnt= cnt-1
        }
    }
        Timer {
            running: true
            onTriggered: button.decrementCnt()
        }

}

I have a error in onClicked: Text{

@isan hi

@isan said in Create button to counting:

And I want, for example, when the first button was selected and the counting started

first do only one button that counts from 3 to 1, then you will write the logic to stop one when you start another

you did syntax error at

 onClicked: Text{
        id: name

after the onClicked: you have to write javascript expression/ call js function,

 Button{
        id: btn
         property int cnt: 3
         text:  cnt

        function decrementCnt(){
            if (cnt>0){
               cnt--
            }else{
                decrementCntTimer.stop()
            }
        }

        Timer {
            id: decrementCntTimer
            repeat: true
            interval: 1000 // 1 second
            onTriggered:{
                console.log("decrementing.")
                btn.decrementCnt()
            }
        }

        onClicked: {
            decrementCntTimer.start()
        }
    }

@LeLev Thank You, I did this because I want to show the count on the button text
Now I do this to show it

onTriggered:{
            console.log("decrementing.")
            btn.text= cnt
            btn.decrementCnt()
         }
