QML: disconnect signal object from all slots from QML

[semlanik]

Hi all!
I can't find full documentation of QML disconnect method.

I use next method to connect signal of "my button" to slots dynamically . Simultaneously I need only one connected slots, so another slots should be disconnected. In my application when i connect "new" slot to button, i need disconnect all "old" slots. But i can't find any API to do this.

Something like this:

button.clicked.disconnect();

does not work. I need make disconnection manually:

button.clicked.disconnect(obj.slot);

It's very inconvenient. Is there some possibility make what i want? if need i can post part of source code.
Thank you!

SelectionDialog {
    id: selectionDialog
}

Button {
    id: btnFirst
    
    property int selectedIndex: 0
    
    onClicked: {
        selectionDialog.model = 10
        selectionDialog.selectedIndex = selectedIndex
        selectionDialog.accepted.connect(callback)
        selectionDialog.open()
    }
    
    function callback() {
        //selectionDialog.accepted.disconnect(callback)
        selectedIndex = selectionDialog.selectedIndex
        console.log("First:", selectedIndex)
    }
}

Button {
    id: btnSecond
    
    property int selectedIndex: 0
    
    onClicked: {
        selectionDialog.model = 4
        selectionDialog.selectedIndex = selectedIndex
        selectionDialog.accepted.connect(callback)
        selectionDialog.open()
