stretch QTableWodgetItem

How to set the QTableWodgetItem to stretch according to the size of QTableWidget ?

Like below.

See QHeaderView::setResizeMode(). You can access the horizontal header via QTableView::horizontalHeader(). In another words, it's a property of the header of the whole view, not an individual item in the view.

Sorry, I made a mistake

What I want exactly is to

1.stretch the QHeaderView according to the size of the QTreeWidget
2.stretch the QTableWidgetItem according to its content

Because if I set the QHeaderView's ReSizeMode to "QHeaderView::ResizeToContents" or "QHeaderView::Stretch", the width of every QTableWidgetItem is fixed to the width of the QHeaderView. And I can not find any function for resizing the QTableWidgetItem.

Sorry, I'm not sure if I follow. QHeaderView is what controls column widths in both QTreeView and QTableView. No particular item in a view can be of different width than what the column is. There must be at least one stretching column if you want the header to fill all available space.

I understand your meaning. But after I set the QHeaderView's resizemodel to "QHeaderView::ResizeToContents", it turns out like the pic. Seems that the QheaderView only resize to the content of itself?

I found the problem.

The setResizeModel must be called every time after adding some items to the QTableWidget.

Now it works fine.

Thank you very much for your help jpn
