QML - TableView - Access TableViewColumn property inside headerDelegate

1
votes

I have custom headerDelegate inside TableView. I need to access properties of TableViewColumn such as resizable property inside headerDelegate.

Is there any way to access this property inside headerDelegate?

Is it possible to access user defined properties in TableViewColumn inside headerDelegate?

For example can I create a user defined property called enableSorting inside TableViewColumn and access it inside headerDelegate in order to hide or show sortingIndicator?

UPDATE

TableView{

 TableViewColumn{
    property bool sortingEnabled: false
    resizable: false
}

 headerDelegate: Rectangle {
   color: styleData.resizable?"red":"blue"
   border.color:styleData.sortingEnabled?"red":"blue"
 }

}

Here styleData.resizable & styleData.sortingEnabled are imaginary. I would like to get something like that.

What you want is to set the TableView id property. You will be able to access it from the entire file scope in all the way you want.

TableView{
    id: myTableView
    headerDelegate: Rectangle {
       color: myTableView.whatever // Change whatever by any property of myTableView
    }
}

Important note : Setting the delegate id and accessing the other way around will not work because it is not instanciated right at the reading of the qml interpreter, plus it probably would target several instances of delegate items.

From the documentation of TableView, to access a column we can use

getColumn(index) method

TableView{

 TableViewColumn{
    property bool sortingEnabled: false
    resizable: false
}

 headerDelegate: Rectangle {
   color: getColumn(styleData.column).resizable?"red":"blue"
   border.color:getColumn(styleData.column).sortingEnabled?"red":"blue"

 }

}
