How to get TableView's row height value?

Does rowDelegate.height work for you? Or just chekcing the delegate you have connected?

No, i dont know how to access height property of rowDelegate.
I want get row height value to set same height in my custom section delegate.

But this sets the height for all rows:

    TableView
    {
        id: tableView
        anchors.fill: tableArea
        headerDelegate: headersDel
        rowDelegate:
        Rectangle
        {
            height: 30 // Height for all columns
        }

...
}

and in your column delegate you can use:

    Component
    {
        id: iconRowDelegate
        Image
        {
            anchors.fill: parent            
            fillMode: Image.Pad
            source: "Icon.png"
        }
    }

I don't want to redefine rowDelegate, i want get height from it (since it differs depending on platform and pixel density).
Question become: how to access rowDelegate's height property?

@morte Since there is no other way, for now, you can use private properties.

console.log(tableview.__currentRowItem.height) 
//tableview = id of TableView

I get actual height value, but first row in view not draws after that, i don't know why yet.

TableView {
	id: view
	property int row_height
    anchors.fill: parent
	section.delegate: section_delegate
     Component.onCompleted {
        currentRow = 0;
        row_height = ____currentRowItem.height;
     }
}

Component {
	id: section_delegate
	Rectangle {
		width: view.width
		height: view.row_height
	}
}

@morte Can you explain with an example what you are trying to do ?

[morte]

@p3c0
There is TableView with my section delegate and i want to set section delegate's height same as height of rows in view.

[p3c0]

@morte You will need to set current item in TableView. You can do this by using currentRow of TableView.

Component.onCompleted: tableView.currentRow = 0

@p3c0
Thats it, thanks!

[morte]

@p3c0
I have just tested it: anyway setting
Component.onCompleted: tableView.currentRow = 0
in view gives incorrect behavior of view

[p3c0]

@morte Do you get the height properly after setting currentRow ?

TableView {
	id: view
	property int row_height
    anchors.fill: parent
	section.delegate: section_delegate
     Component.onCompleted {
        currentRow = 0;
        row_height = __currentRowItem.height;
     }
}

Component {
	id: section_delegate
	Rectangle {
		width: view.width
		height: view.row_height
	}
}

@morte What do you mean by not draws ? See if you get updated height inside the Component.
