select_command -- A callable which will be called when a tab is
selected. It is called with the name of the selected tab as an
argument.
tabs -- A list of strings, the names of the tabs. Should be specified in
the desired tab order. The first tab will be the default and first
active tab. If tabs is None or empty, the TabSet will be initialized
empty.
n_rows -- Number of rows of tabs to be shown. If n_rows <= 0 or is
None, then the number of rows will be decided by TabSet. See
_arrange_tabs() for details.
max_tabs_per_row -- Used for deciding how many rows of tabs are needed,
when the number of rows is not constant. See _arrange_tabs() for
details.

Arrange the tabs in rows, in the order in which they were added.
If n_rows >= 1, this will be the number of rows used. Otherwise the
number of rows will be calculated according to the number of tabs and
max_tabs_per_row. In this case, the number of rows may change when
adding/removing tabs.

With TabbedPageSet, this calls TabbedPageSet.change_page, so that
selecting a tab changes the page.
Note that this does -not- call set_selected -- it will be called by
TabSet.set_selected_tab, which should be called when whatever the
tabs are related to changes.

TabbedPageSetaj A Tkinter tabbed-pane widget.
Constains set of 'pages' (or 'panes') with tabs above for selecting which
page is displayed. Only one page will be displayed at a time.
Pages may be accessed through the 'pages' attribute, which is a dictionary
of pages, using the name given as the key. A page is an instance of a
subclass of Tk's Frame widget.
The page widgets will be created (and destroyed when required) by the
TabbedPageSet. Do not call the page's pack/place/grid/destroy methods.
Pages may be added or removed at any time using the add_page() and
remove_page() methods.

page_names -- A list of strings, each will be the dictionary key to a
page's widget, and the name displayed on the page's tab. Should be
specified in the desired page order. The first page will be the default
and first active page. If page_names is None or empty, the
TabbedPageSet will be initialized empty.
n_rows, max_tabs_per_row -- Parameters for the TabSet which will
manage the tabs. See TabSet's docs for details.
page_class -- Pages can be shown/hidden using three mechanisms:
* PageLift - All pages will be rendered one on top of the other. When
a page is selected, it will be brought to the top, thus hiding all
other pages. Using this method, the TabbedPageSet will not be resized
when pages are switched. (It may still be resized when pages are
added/removed.)
* PageRemove - When a page is selected, the currently showing page is
hidden, and the new page shown in its place. Using this method, the
TabbedPageSet may resize when pages are changed.
* PagePackForget - This mechanism uses the pack placement manager.
When a page is shown it is packed, and when it is hidden it is
unpacked (i.e. pack_forget). This mechanism may also cause the
TabbedPageSet to resize when the page is changed.
