Disable QTreeView/QTreeWidget keyboard navigation
Message 1 in thread
Is there a way to disable QTreeView/QTreeWidget keyboard navigation?
I'm using a QTreeWidget to display a list of item summaries. I want to
make it where users can click on an item, but not be able to use the
arrow keys to navigate up/down the list. I'm not seeing any function to
display key presses.
The only thing I can think of is to create my own class that inherits
from QTreeWidget and reimplement QTreeWidget::keyPressEvent() and just
have it ignore all key press events.

Another thing I can think of is installing an event filter eating
the key events. Probably less code.

This looks perfect, in fact the example shown in the Qt docs shows them creating a "key press eater" event filter, so it looks like it's just a copy/paste job for me!
Thanks,
Sean

you can overwrite the func QTreeView::moveCursor(CursorAction cursorAction, Qt::KeyboardModifiers modifiers) and do nothing in the func, so there would be no keyboard navigation Regards,Reimand

myTreeWidget->setFocusPolicy(Qt::NoFocus);

Thanks! This works perfectly and seems like the simplest solution.
