Hello Forum

I want to transform a static structure to a dynamic :

Example:
Qt Code: 
  1. ListModel {
  2.         ListElement {
  3.             categoryName: "ABC"
  4.             subItems: [
  5.                 ListElement { itemName: "aaa"},
  6.                 ListElement { itemName: "bbb"}
  7.             ]
  8.         } 
  9.         ListElement {
  10.             categoryName: "ABC"
  11.             subItems: [
  12.                 ListElement { itemName: "aaa"},
  13.                 ListElement { itemName: "bbb"}
  14.             ]
  15.         }
  16.         ListElement {
  17.             categoryName: "ABC"
  18.             subItems: [
  19.                 ListElement { itemName: "aaa"},
  20.                 ListElement { itemName: "bbb"}
  21.             ]
  22.         }
  23.     }

Dynamic :
Qt Code: 
  1. ListModel {
  2.        Component.onCompleted: {
  3.           for(var i = 0; i < 2; ++i) {
  4.              append({
  5.                        "categoryName": "ABC",
  6.                        "subItems": [
  7.                           {"itemName": "aaa"},
  8.                           {"itemName": "bbb"}
  9.                        ]
  10.                     })
  11.           }
  12.        }
  13.     }
To copy to clipboard, switch view to plain text mode 

Until here everything is good


My Question: How can I transform the below static structure to dynamic

Qt Code: 
  1. ListModel {
  2.         ListElement {
  3.             categoryName: "ABC"
  4.             subItems: [
  5.                 ListElement { itemName: "aaa"},
  6.                 ListElement { itemName: "bbb"}
  7.             ]
  8.         } 
  9.         ListElement {
  10.             categoryName: "DEF"
  11.             subItems: [
  12.                 ListElement { itemName: "ccc"},
  13.                 ListElement { itemName: "ddd"}
  14.             ]
  15.         }
  16.         ListElement {
  17.             categoryName: "GHI"
  18.             subItems: [
  19.                 ListElement { itemName: "eee"},
  20.                 ListElement { itemName: "fff"},
  21.                 ListElement { itemName: "ggg"}
  22.             ]
  23.         }
  24.     }
To copy to clipboard, switch view to plain text mode 

The problem is I don't know the size of SubItems !!

First : I get the projects (list of project)
Second : I get for each project list of files (list of files)

I want to present this structure :
project0
file1
file2
project1
file3
file4
project2
file5
file6
file7

I try this, not work well !
Qt Code: 
  1. ListModel {
  2.          id: menuModel
  3.          Component.onCompleted: {
  4.  
  5.              var listProjects = handledProjets()
  6.              for(var k=0; k<listProjects.length; k++)
  7.              {
  8.                  var nameplugin = listProjects[k]
  9.                  console.log(">>> Projet = "+nameplugin)
  10.                  //menuModel.append({text:nameplugin})
  11.                 //append({"categoryName": nameplugin})
  12.  
  13.                var listFiles = handledFiles(nameplugin)
  14.                      console.log(">>> File("+(l+1)+") = "+listFiles[l])
  15.                      //mychild.append({text:listFiles[l]})
  16.                      append({
  17.                                     "categoryName": nameplugin
  18.                                     "subItems": [
  19.                                     {"itemName": listFiles[l]}
  20.                                 ]
  21.                             })
  22.                  }
  23.              }
