Remove all sub-elements of an item in QTreeView

I have a QTreeView with an element baseItem which itself contains some children:

baseItem
  - child1
  - child2
  - child3

Now I want to delete all children of this item but not the item itself. My current approach is to call

if (baseItem->hasChildren())
    baseItem->removeRows(rowCnt,baseItem->rowCount());

...where rowCnt is the row index number where baseItem is located at. Unfortunately this does work only when baseItem is at rowCnt=0. What could be wrong here? How else should I delete all children of baseItem?

Thanks!

Solution

  • ...where rowCnt is the row index number where baseItem is located at.

    No, rowCnt is the index in the subtree under the parent. So:

    if (baseItem->hasChildren())
    baseItem->removeRows(0,baseItem->rowCount());
