QTreeWidgetItemIterator howto

[seneca]

I want to loop through the topmost items of a QTreeWidget. I guess this would be most convenient done with the new QTreeWidgetItemIterator class introduced with 4.1.

Does anybody know where to find documentation or a sample how it works? Seems it is not yet in the Qt Assistant (at least in the 4.1 commercial)

And there is such an iterator? If it's not documented, then it's probably not for public use.

Use this:

int ind=0;
while(QTreeWidgetItem *item = treeWidget->topLevelItem(ind)){
  doSomething(item);
  ind++;
}

int ind=0;
while(QTreeWidgetItem *item = treeWidget->topLevelItem(ind)){
  doSomething(item);
  ind++;
}

It's in the 4.1 changelog. I think you should report to the tasktracker as a bug.

Thanks for the loop wysota, it works for my current need.

I have asked TT to provide documentation/how-to for the new class.

Attached you find the documentation from the snapshot along with a small example that I received from trolltech support.
