Question

I would like to use a stylesheet :focus pseudo-state to control the representation of the Tree view’s focus state. Using the following stylesheet works well, except that the Qt system still draws it’s own focus rect. How do I ask Qt to not draw the focus rect, while still being able to focus the control for keyboard input?

QTreeView {
    background: #505050;
    border: 1px solid;
    border-radius: 10px;
}

QTreeView:focus { 
    border: 2px groove;
}

Answer 1

The focus rect around the QTreeView widget itself turns out to be a Mac styling feature. This turns it off per widget:

tree.setAttribute(Qt.WA_MacShowFocusRect, 0)
