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: 
  1. import QtQuick 2.2
  2. import QtQuick.Controls 1.4
  3. import QtQml.Models 2.2
  4. import KMTreeModelPM 1.0
  5.  
  6. Item {
  7.  
  8.     KMTreeModelPM {
  9.         id: treeModel
  10.     }
  11.  
  12.     ItemSelectionModel {
  13.         id: sel
  14.         model: treeModel
  15.     }
  16.     Text {
  17.         id:txt
  18.         text: " "
  19.     }
  20.  
  21.  
  22.     TreeView {
  23.         id: view
  24.         anchors.fill: parent
  25.         anchors.margins:  12
  26.         selection: sel
  27.         headerVisible : false
  28.         itemDelegate: Rectangle {
  29.                    color: ( styleData.row % 2 == 0 ) ? "white" : "lightblue"
  30.                    height: 20
  31.  
  32.                    Text {
  33.                        anchors.verticalCenter: parent.verticalCenter
  34.                        anchors.left: parent.left // by default x is set to 0 so this had no effect
  35.                        text: styleData.value
  36.                    }
  37.                }
  38.         TableViewColumn {
  39.             id : title
  40.             title: "Title"
  41.             role: "title"
  42.             resizable: true
  43.             horizontalAlignment : Text.AlignLeft
  44.         }
  45.         model: treeModel
  46.  
  47.         onDoubleClicked: txt.text = treeModel.data(index,0) 
  48.  
  49.     }
  50.  
  51. }
