<td colspan=2><tt>Base class for Tkinter widgets with scrollbars.<br>
The widget is a standard Tkinter.<a href="ttk.html#Frame">Frame</a> or a ttk.<a href="ttk.html#Frame">Frame</a> if ttk is available,<br>
with an additional configuration option SCROLLMODE which may be one of<br>
"x", "y", "both" or "auto".<br>
If SCROLLMODE is one of "x", "y" or "both", one or two static scrollbars<br>
will be drawn. If SCROLLMODE is set to "auto", two automatic scrollbars<br>
that appear only if needed will be drawn.<br>
In order to ensure backwards compatibility, ttk-incompatible configuration<br>
options passed to the widget or to the scrollbars will be silently ignored<br>
if ttk widgets are used.<br>
The Scrollbar widgets can be accessed with the hbar and vbar class<br>
attributes. Derived classes must override the _setScrolledWidget() method,<br>
which must return the widget that will be scrolled and should add a class<br>
attribute that allows to access this widget, so the _setScrolledWidget()<br>
method for a ScrolledListbox widget might look like:<br>
<br>
def _setScrolledWidget(self):<br>
self.<strong>listbox</strong> = Tkinter.Listbox(self)<br>
return self.<strong>listbox</strong><br>
<br>
Note that although it should be possible to create scrolled widget classes<br>
for virtually any Listbox or Canvas alike Tkinter widget you can *not*<br>
safely use this class to add automatic scrollbars to a Text or Text alike<br>
widget. This is because in a scrolled Text widget the value of the<br>
horizontal scrollbar depends only on the visible part of the Text, not on<br>
it's whole contents. Thus it may happen that it is the last visible line of<br>
text that causes the automatic scrollbar to be mapped which then hides this<br>
last line so it will be unmapped again, but then it is requested again and<br>
gets mapped and so on forever. There are strategies to avoid this, but<br>
usually at the cost that there will be situations where the horizontal<br>
scrollbar remains mapped although it is actually not needed. In order to<br>
acomplish this with the <a href="#ScrolledWidget">ScrolledWidget</a> class, at least the _scrollXNow()<br>
and _scrollBothNow() methods must be overridden with appropriate handlers.<br> </tt></td></tr>
