TableView with CheckBox in header

PhTe

Hi,
i have a QML TableView and would like to put a checkbox in the header row.
Therefore i added a checkbox to the headerDelegate, but if i click on it, it does not change its state. Its always 'checked'.

Has anyone an idea why i can not click on the checkbox.
I also tried to a add a MouseArea to the header but it seems it will be ignored as well.

My code looks like:

TableView {
            id: tableView
            height: parent.height
            width: parent.width/2

...

headerDelegate: Item {
                height: 20
                anchors.left: parent.left
                anchors.right: parent.right

                CheckBox {
                    anchors.centerIn: parent
                    id: activateAllEvents
                    checked: true
                    visible: styleData.column === 4 // Show only in the 4th column
                    activeFocusOnPress: true
                    text: ""
                }
            }
}

@PhTe Are some signals emitted when you click checkbox (clicked(), pressed())?

PhTe

@medyakovvit No there are no signals emitted.

I tried

onClicked: {
    console.log("onClick");
}
onPressedChanged: {
    console.log("onPressedChanged");
}
onCheckedChanged: {
    console.log("onCheckedChanged");
}

but none of the functions are called if i click on the checkbox.

@PhTe, workaround:

headerDelegate: Item {
                height: 20
                anchors.left: parent.left
                anchors.right: parent.right

                CheckBox {
                    id: activateAllEvents
                    anchors.centerIn: parent
                    
                    property bool myPressed: styleData.pressed
                    checked: true
                    visible: styleData.column === 4 // Show only in the 4th column
                    activeFocusOnPress: true
                    text: ""
                    onMyPressedChaged: {
                        if(myPressed)
                            checked = !checked;
                    }
                }
            }
