QStandardItemModel

[neda]

Hi,

I want to bind QStandardItemModel to a table(TableView or GridView or ...) with several rows and columns.

Table must have not any scroll and height of table is equal of count of row.

I can show QStandardItemModel in tableview but height of it more than from count of row.

I can show QStandardItemModel in GridView but it can show just one record.

Please gide me.

TableView {
                            id: tablemodel
                            anchors.fill: parent
 
                            model: myXML.newMyModel
 
 
                            MyTableViewColumn {
                                role: "field1"
                            }
                            MyTableViewColumn {
                                role: "field2
                            }
                            MyTableViewColumn {
                                role: "field3
                            }
                            MyTableViewColumn {
                                role: "field4
                            }

Well, this obviously isn't the code you are using.

Can you show the roleNames() implementation of your QStandardItemModel subclass and how you create a "row" item?

That looks good.
So you are saying that if you do this

GridView {
    anchors.fill: parent
    model: myXML.newMyModel
 
    delegate: Text {
        text: "index"
    }
}

GridView {
    anchors.fill: parent
    model: myXML.newMyModel

    delegate: Text {
        text: "index"
    }
}

To copy to clipboard, switch view to plain text mode 

you are only getting one item in the grid?

Yes

Very strange.
What's the value of the GridView's count property?

Have you tried with a ListView just to check that you can access all model data?
