By default, each window has four binding tags consisting of the name of the window, the window's class name, the name of the window's nearest toplevel ancestor, and all, in that order. Toplevel
windows have only three tags by default, since the toplevel name is the same as that of the window. The bindtags command allows the binding tags for a window to be read and modified.
If bindtags is invoked with only one argument, then the current set of binding tags for window
is returned as a list. If the taglist
argument is specified to bindtags, then it must be a proper list; the tags for window
are changed to the elements of the list. The elements of taglist
may be arbitrary strings; however, any tag starting with a dot is treated as the name of a window; if no window by that name exists at the time an event is processed, then the tag is ignored for that event. The order of the elements in taglist
determines the order in which binding scripts are executed in response to events.
@example reversing order for .b
tags = Bindtags.bindtags('.b')
Bindtags.bindtags('.b', *tags.reverse)
The above example reverses the order in which binding scripts will be evaluated for a button named `.b` so that all bindings are invoked first, following by bindings for `.b`'s toplevel (`.`), followed by class bindings, followed by bindings for `.b`. If taglist
is an empty list then the binding tags for window
are returned to the default state described above.
