I'm not sure what you mean but you can control the looks of items by changing a delegate of the view.

I want add a headitem like QTreeview's column in the Qlistview or Qlistwidget.
Sorry my english is not very good:)

It doesn't make much sense as QListView only has a single column so you won't see much but if you want then use QAbstractScrollArea::setViewportMargins() to "push" the contents of the viewport down and then you can place a QHeaderView there. Then you'll need to reimplement resizeEvent() for the list so that you can update the geometry of the header when the width of the list changes.

how can i let the listview like this:
------------------------------------------------------------
|1 |2 |3 |4 |
------------------------------------------------------------

you can't because list view has a one column always. Just use QTreeView with only one level of items, so it will look like list, and you can have as many colums you want.

But teacher ask we write a program that the list must have columns "name,age,department",and you can add information.It also can change to icon mode ro list mode (icon mode don't have columns)

how can i do that??

As wysota said in #2,, delegates :)
Have a look at QItemDelegate and QStyledItemDelegate
