[Solved]Nested List Model Dynamic Data Population

haris123

Basically what I want to implement is populate list model

@ListModel {
id: nestedModel
}@

to some thing like,

@nestedModel.append({
locationName: qsTr("Location5"),
collapsed: true,
folders: [{
folderName: qsTr("Cam11")
}, {
folderName: qsTr("Cam22")
}, {
folderName: qsTr("Cam33")
}, {
folderName: qsTr("Cam44")
}]
})

        nestedModel.append({
            locationName: qsTr("Location1"),
            collapsed: true,
            folders: [{
                 folderName: qsTr("Cam11")
                 }, {
                 folderName: qsTr("Cam22")
                 }, {
                  folderName: qsTr("Cam33")
                 }, {
                 folderName: qsTr("Cam44")
                  }]
          })@

and which works fine.

But I have to do both parent and child list separately. Here parent is "locationName" and child is "folders"

I can success fully update "locationName" using

@for(var i=0;i<locations.length;i++){
nestedModel.append({
locationName: locations[i],
collapsed: true
})
}@

But how can I update "folders" in separate loop as I get the folders list after locations list.

I already tried like

@ListModel {
id:diractories
}

diractories.clear();
 for(var j=0;j<dirs.length;j++){
   diractories.append({ folderName: dirs[j] })
   console.log(diractories.get(j).folderName)
}

nestedModel.set(list_view.currentIndex, {folders: diractories})@
Where I have added an extra item "folders" at the first time, like

@nestedModel.append({
locationName: locations[i],
collapsed: true
folders:diractories
})@

But all my "folders" list looks same for every "locationName".

So my question is how can add data for "folders" dynamically?

Thanks

Sorry but i don't understand what you want. What is the problem, filling the model, or updating/repainting of the list element? Maybe post you source.

hi, thanks for reply..

Actually I am stuck with filling the model, I can successfully fill the parent, but about child list I am confuced..

Finally I found the answer "here":http://www.codeproject.com/Articles/632795/QML-TreeModel-and-TreeView
I just used below code to append new data to child list,

@nestedModel.get(index).folders.append({"folderName": "Cam55})
nestedModel.get(index).folders.append({"folderName": "Cam66})@
