python - How to select or highlight all items in a QTreeWidget? -

-

i'm trying build context menu user can right-click on qtreewidget , select items.

you can use qtreeview.selectall() after setting selection mode allows multiple selection (using qabstractitemview.setselectionmode()).

example (in pyqt4 use qtgui instead of qtwidgets):

from pyqt5 import qtwidgets  app = qtwidgets.qapplication([])  widget = qtwidgets.qtreewidget() widget.addtoplevelitems([qtwidgets.qtreewidgetitem(['dog']), qtwidgets.qtreewidgetitem(['car'])]) widget.setselectionmode(qtwidgets.qabstractitemview.contiguousselection) widget.selectall()  widget.show()  app.exec_()

and looks like:
