HI thanks for the reply.
What i want is have a display dimensional form like below
and the number of lists ie (Alist ,Blist,Clist is dynamic is realtime) and the items within the list a1,a2,a3 are also real time.
Tell me how do I create them dynamically and access it in Qml.
I am open to any approach
Alist a1,a2,a3
Blist b1,b2,b3
Clist c1,c2

For dynamic list, there are many ways to archive it.

For dynamic item:
@ListModel
{
id:vip_list;
ListElement{name:"aaa";status:"invalid"; time:"2011-01-15..."}
ListElement{name:"bbb";status:"invalid"; time:"2011-11-11..."}
}@

JS code:
@vip_list.append({name:"ccc", status:"ok", time:"2011-01-01"});@

For most case, you may combine the above with signal:
JS code:
@onDataReceived:
{
vip_list.append({name:PARAM1_FROM_SIGNAL, status:PARAM2_FROM_SIGNAL, time:PARAM3_FROM_SIGNAL});
}@

For access, you can try
@vip_list.get(index).name
vip_list.get(index).status
vip_list.get(index).time@

Hi, Hi,
I have a situation where i have to display multiple lists corresponding to
different parent.

Alist A1 | A2| A3 | A4
Blist B1 | B2| B3
CList C1 | C2
DList D1 | D2| D3 |D4

The parents and the child elements i get are in different vectors.
I will have to classify them into different lists based on the parent id and
display them in qml.
The number of parent elements and number of child elements are variable.

I am able to do the appending through C++.

suppose i create a master list which has lists in it

@
masterlist[0] ="A",list[A1 , A2, A3 , A4]
masterlist[1] ="B",list[B1 , B2, B3 ]
masterlist[2] ="C",list[C1 , C2 ]
masterlist[3] ="D",list[D1 , D2, D3 , D4]
@

how do I access the list from my Qml like model :materlist.sublist.
You can suggest any other approach
