display text in tableviewcolumn in treeView QtQuick controls 1.4

[mohy]

Hi all,

Im trying to create a simple treeView appeared in Qt 5.5 , the problem is that the text in items of the tree doesn't display, despite the model is full.

There is my code :

TreeViewPM.qml

Qt Code:
Switch view

import QtQuick 2.2
import QtQuick.Controls 1.4
import QtQml.Models 2.2
import KMTreeModelPM 1.0
 
Item {
 
    KMTreeModelPM {
        id: treeModel
    }
 
    ItemSelectionModel {
        id: sel
        model: treeModel
    }
    Text {
        id:txt
        text: " "
    }
 
 
    TreeView {
        id: view
        anchors.fill: parent
        anchors.margins:  12
        selection: sel
        headerVisible : false
        itemDelegate: Rectangle {
                   color: ( styleData.row % 2 == 0 ) ? "white" : "lightblue"
                   height: 20
 
                   Text {
                       anchors.verticalCenter: parent.verticalCenter
                       anchors.left: parent.left // by default x is set to 0 so this had no effect
                       text: styleData.value
                   }
               }
        TableViewColumn {
            id : title
            title: "Title"
            role: "title"
            resizable: true
            horizontalAlignment : Text.AlignLeft
        }
        model: treeModel
 
        onDoubleClicked: txt.text = treeModel.data(index,0) 
 
    }
 
}

To copy to clipboard, switch view to plain text mode

main.qml

Qt Code:
Switch view

import QtQuick 2.2
import QtQuick.Controls 1.4
import QtQml.Models 2.2
import QtQuick.Layouts 1.1
import QtQuick.Controls.Styles 1.4
 
Rectangle {
    width: 785
        TabView {
            x: 17
            y: 8
            width: 970
            height: 800
            currentIndex: 2
            visible: true
            Tab {
                id: tabAddProfile
                title: qsTr("Add Profile")
                AddProfilePage{}
            }
            Tab {
                id: tabAddTypeSubType
                title: qsTr("Add Type/SubType")
                AddTypeSubTypePage{}
            }
            Tab {
                id: tabAddDetail
                height: 413
                visible: true
                title: qsTr("Add Detail")
                TreeViewPM {}
            }
 
        }
 
    }

Hi @mohy
Is KMTreeModelPM a C++ model ? Can you share its code ?
