Getting Child Items from QStandardItemModel

[nikhilqt]

Hi Guys,

I have a QStandardItemModel. I need to get a Children QVariantList OR QStandardItemModel itself by giving an QModelIndex() of the parent.

For ex: A tree as below,

+Parent1
      + Child10
       - Child11
          - GrandChild110
          - GrandChild111
          - GrandChild112
+Parent2
      + Child20
       - Child21
           - GrandChild210
           - GrandChild211
           - GrandChild212
+Parent3

+Parent1
      + Child10
       - Child11
          - GrandChild110
          - GrandChild111
          - GrandChild112
+Parent2
      + Child20
       - Child21
           - GrandChild210
           - GrandChild211
           - GrandChild212
+Parent3

By giving the QModelIndex() of parent item "Parent1" I need to get a QVariantList or QStandardItemModel of the children Items of the
same. Like.

+ Child10
       - Child11
          - GrandChild110
          - GrandChild111
          - GrandChild112

+ Child10
       - Child11
          - GrandChild110
          - GrandChild111
          - GrandChild112

To copy to clipboard, switch view to plain text mode 

Please let me know how it can be done.

Thanks
Nikhil

This looks like a job for a proxy model. My knowledge level is not really good enough to rattle off an exact solution. Have a read of the QAbstractProxyModel documentation and a look at the browser demo's history handling models and this related QtLabs article.

Guys, Anybody who have done like this. Please help me out.

Thanks.

Hey!

treeView->setRootIndex(...) will do the necessary. Thanks.

Hi,

I am also facing the similar issue, but I didnt get the usage of "treeView->setRootIndex(...)". Could you please explain more?
