pub fn check_focus(ui: &mut Ui, place: &str) -> Vec<Finding>Expand description
Presses Tab across the screen and says whether the focus moves and reaches every control. The focus is left where the last press put it.
What the application changes by itself on the way, such as a reminder that comes due, is not held against the screen: a control counts as never reached only when it is there from the first press to the last, and a window that opens on the way ends the walk.
