Get data of the ListElement, which is currently bound to the TableView

[Xequtor]

Hello All,

I am trying to achieve the following: Add a table, which will have one column with delegates (TextFields, SpinBoxes, etc) and the rest of the columns will be just texts, taken from ListModel. What control will be added on the current row depends on one of the properties in the ListModel. I am adding the controls by a Loader and I have a script, which returns a delegate of the respective control. In order to decide which element to put in the current row, I need to know the value of the ListElement's property in the current row. This is my code:

 Item {
            id: propertiesTableContainer
            anchors.top: propertiesFilter.bottom
            anchors.topMargin: 10
            anchors.bottom: parent.bottom
            width: parent.width

            Item {
                id: propertiesDelegatesContainer

                Component {
                    id: propertiesTextBoxDelegate
                    TextField {}
                }

                Component {
                    id: propertiesSpinBoxDelegate
                    SpinBox {
                        stepSize: lStepSize
                        decimals: lDecimalCounts
                    }
                }

                Component {
                    id: propertiesCheckboxDelegate
                    CheckBox {}
                }
            }

            ListModel {
                id: propertiesModel

                ListElement {
                     name: "gAudioSongTitle"
                     value: ""
                     description: "The title of currently playing song"
                     type: "String"
                     range: ""
                }

                ListElement {
                     name: "gAudioSongTotalTime"
                     value: ""
                     description: "The title of currently playing song"
                     type: "Int"
                     range: ""
                }

                ListElement {
                     name: "gAudioSongTotalTime"
                     value: ""
                     description: "The title of currently playing song"
                     type: "Bool"
                     range: ""
                }

                ListElement {
                     name: "gAudioSongTotalTime"
                     value: ""
                     description: "The title of currently playing song"
                     type: "float"
                     range: ""
                }
            }

            TableView {
                id: propertiesTable
                anchors.top: parent.top
                anchors.bottom: parent.bottom
                model: propertiesModel
                width:parent.width

                TableViewColumn {
                    id: propertiesColumnName
                    role: "name"
                    title: "Name"
                    elideMode: Text.ElideRight

                }
                TableViewColumn {
                    id: propertiesColumnValue
                    role: "value"
                    title: "Value"
                    width: 200

                    delegate: Loader {
                        anchors.fill: parent
                        property real lStepSize: 0.1
                        property int lDecimalCounts: 1

                        sourceComponent: {
                            switch(propertiesModel.get(0).type)
                            {
                                case "String":
                                case "string":
                                    console.log(lPropertiesTableCurrentRow);
                                    return propertiesTextBoxDelegate;
                                case "Int":
                                case "int":

                                    lStepSize = 1.0;
                                    lDecimalCounts = 0;
                                    return propertiesSpinBoxDelegate;
                                case "Float":
                                case "float":
                                case "Double":
                                case "double":
                                case "Real":
                                case "real":
                                    console.log(lPropertiesTableCurrentRow);
                                    lStepSize = 0.1;
                                    lDecimalCounts = 1;
                                    return propertiesSpinBoxDelegate;
                                case "Boolean":
                                case "Bool":
                                case "bool":
                                    console.log(lPropertiesTableCurrentRow);
                                    return propertiesCheckboxDelegate
                                default:
                                    console.log(lPropertiesTableCurrentRow);
                                    return propertiesTextBoxDelegate;
                            }
                        }
                    }
                }
                TableViewColumn {
                    id: propertiesColumnDescription
                    role: "description"
                    title: "Description"
                    elideMode: Text.ElideRight
                    width: 200
                }
                TableViewColumn {
                    id: propertiesColumnType
                    role: "type"
                    title: "Type"
                    elideMode: Text.ElideRight
                    width: 100

                }
                TableViewColumn {
                    id: propertiesColumnRange
                    role: "range"
                    title: "Range"
                    elideMode: Text.ElideRight
                    width: 100
                }
            }

        }

As you can see I am trying to get the value by this expression:

propertiesModel.get(0).type

I need either to replace the 0 with the index of the currently processed ListElement or find another way to get the data from the type column. I tried to use on global property, which starts at 0 and I increase it by one everytime a delegate is loaded, but then I've got Binding Loop error. It was like this:

propertiesModel.get(globalProperty++).type

So, is it possible to achieve what am I trying to, or should I try to find another way (without using TableView)

Thanks,

Make switch statement like this. It should solve your problem.

switch(propertiesModel.get(styleData.row).type)

A huuuuuge thanks, @dheerendra . You really saved my day :)
