takefocus |

Determines whether the window accepts the focus during keyboard traversal (e.g., Tab and Shift-Tab). Before setting the focus to a window, the traversal scripts consult the value of the takeFocus option. The value #f means that the window should be skipped entirely during keyboard traversal; #t means that the window should receive the input focus as long as it is viewable (it and all of its ancestors are mapped). An empty value () for the option means that the traversal scripts make the decision about whether or not to focus on the window: the current algorithm is to skip the window if it is disabled, if it has no key bindings, or if it is not viewable. |
