How do I make qtreewidget header transparent?

I want the treewidget header to look as if it's a label, so, I guess, I have to make it transparent? How do I do it?

I tried treeWidget->setStyleSheet("QTreeWidget::header {background-color: transparent}"); but it doesn't work.

Solution

  • The header is not a subcontrol of an itemview, thus QTreeWidget::header will not work. The header rather is a children widget of the view. That means you could access the header via stylesheets with QTreeWidget QHeaderView {/*style here*/ }

    For the background color of a header view you can check out the official Qt example.

    In your case as you are setting the stylesheet directly to the view you can omit the parent so the following will do what you asked for:

    treeWidget->setStyleSheet("QHeaderView::section { background-color: transparent; }");
