QTreeWidget, resizing item and widgets problem

[The Storm]

Hi all,

I will explain basicly - I have items with icons and some text on it, when item is clicked I place a widget on it, so far so good, but when the treewidget is resized the icon of the item below the widget is showing up, how I can avoid this to happen, here two screenshots to make it more clear.

The first screen is the correct effect before to resize the TreeWidget, and the second is after I resized the TreeWidget, as you see the icon of the item that is under the widget shows up and I don't want that to happen.
