class ScrolledMultiListbox(ScrolledWidget) |
| |
MultiListbox widget with one or two static or automatic scrollbars.
Subwidgets are:
listbox - TkTreectrl.MultiListbox widget
hbar - horizontal Tkinter.Scrollbar or ttk.Scrollbar
vbar - vertical Tkinter.Scrollbar or ttk.Scrollbar
The widget itself is a Tkinter.Frame or ttk.Frame with one additional
configuration option:
scrollmode - may be one of "x", "y", "both" or "auto".

class ScrolledTreectrl(ScrolledWidget) |

Treectrl widget with one or two static or automatic scrollbars.
Subwidgets are:
treectrl - TkTreectrl.Treectrl widget
hbar - horizontal Tkinter.Scrollbar or ttk.Scrollbar
vbar - vertical Tkinter.Scrollbar or ttk.Scrollbar
The widget itself is a Tkinter.Frame or ttk.Frame with one additional
configuration option:
scrollmode - may be one of "x", "y", "both" or "auto".

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