[SOLVED] ExclusiveGroup current usage

[literA2]

Hi,

I would like to ask how to use the exclusive groups's current in RadioButtons.
I have this example:

Item {
 property string currVal

 ExclusiveGroup {
    id: group
    onCurrentChanged : {
       console.log(current.value) // this returned an undefined
    }
 }

 CustomRadioButton {
        id: topButton
        text: qsTr("Top")
        checked: true
        exclusiveGroup: group
        value: "top"
    }
    CustomRadioButton {
        id: bottomButton
        text: qsTr("Bottom")
        exclusiveGroup: group
        value: "bottom"
    }
 }

Question: How can i get the value of the current object in ExclusiveGroup?

Am I doing wrong? Please advise. Thanks.

what you are doing is correct. Can you paste your CustomRadioButton ?
Hope you have done something like the following in CustomRadioButton.qml

RadioButton {
property string value : ""
}

@dheerendra Thanks for the reply.

Yes, I have set a property value on my CustomRadioButton.

But the problem is on the log, it says undefined.

Can you paste your CustomRadioButton code ?

@dheerendra here it is:

Item {
  id: radioItem
  property alias exclusiveGroup: radioButton.exclusiveGroup
  property alias checked: radioButton.checked;
  property alias text: text.text;
  property alias info: infoText.text;
  property string value: ""

  implicitHeight: Math.max(text.implicitHeight, labelColumn.implicitHeight)
  implicitWidth: parent.width

  RowLayout {
   id: layout
   anchors {
    top: parent.top
    left: parent.left
    right: parent.right
  }

  RadioButton {
    id: radioButton
    Layout.alignment: Qt.AlignTop
    style: ControlStyles.RadioButtonStyle {
      indicator: Image {
        readonly property string over: radioButton.pressed ? "-over" : ""
        readonly property string onOff: radioButton.checked ? "on" : "off"

        source: StaticData.getImage("radio-" + onOff + (radioButton.enabled ? over : "-disabled" ) + ".png")
      }
    }
  }

  ColumnLayout {
    id: labelColumn
    Layout.fillWidth: true
    Layout.alignment: Qt.AlignTop

    Text {
      id: text
      Layout.fillWidth: true
     horizontalAlignment: Text.AlignLeft
      wrapMode: Text.WordWrap
    }

    Text {
      id: infoText
      Layout.fillWidth: true
      horizontalAlignment: Text.AlignLeft
      wrapMode: Text.WordWrap
    }
    }
  }
}

Two things.

1. Your CustomRadioButton is not a RadioButton. It contains the radioButton.
2. 'current' object in signal is RadioButton and not the your top level object of type CustomRadioButton.
3. Property 'value' is not in RadioButton object. Hence the error.

You should move the property string value to RadioButton mentioned in customComponent.

Replace you value property like this in Item.
property alias value : radioButton.value

Make your RadioButton like this.

    RadioButton {
        id: radioButton
        Layout.alignment: Qt.AlignTop
        objectName: "Dheeru"
        property string value: ""
    }
