Determines if the element element accepts the focus for user input, and controls tabstops.
The method on element uses the value of the accepts-focus-p slot, but methods on some subclasses override this.
accepts-focus-p also influences whether a pane is a tabstop. On Microsoft Windows a pane acts as a tabstop if and only if the function accepts-focus-p returns true and the element
accepts-focus-p
initarg value is
:force
. On Motif and Cocoa, a pane acts as a tabstop if and only if the function accepts-focus-p returns true.
