new: :class:`Combobox`, :class:`Notebook`, :class:`Progressbar`,

|

Using the Ttk widgets gives the application an improved look and feel.

As discussed above, there are differences in how the styling is coded.

Spinbox
|
||||
-------
|
||||
The :class:`ttk.Spinbox` widget is a :class:`ttk.Entry` enhanced with increment
|
||||
and decrement arrows. It can be used for numbers or lists of string values.
|
||||
This widget is a subclass of :class:`Entry`.
|
||||
|
||||
Besides the methods inherited from :class:`Widget`: :meth:`Widget.cget`,
|
||||
:meth:`Widget.configure`, :meth:`Widget.identify`, :meth:`Widget.instate`
|
||||
and :meth:`Widget.state`, and the following inherited from :class:`Entry`:
|
||||
:meth:`Entry.bbox`, :meth:`Entry.delete`, :meth:`Entry.icursor`,
|
||||
:meth:`Entry.index`, :meth:`Entry.insert`, :meth:`Entry.xview`,
|
||||
it has some other methods, described at :class:`ttk.Spinbox`.
|
||||
|
||||
Options
|
||||
^^^^^^^
|
||||
|
||||
This widget accepts the following specific options:
|
||||
|
||||
.. tabularcolumns:: |l|L|
|
||||
|
||||
+----------------------+------------------------------------------------------+
|
||||
| Option | Description |
|
||||
+======================+======================================================+
|
||||
| from | Float value. If set, this is the minimum value to |
|
||||
| | which the decrement button will decrement. Must be |
|
||||
| | spelled as ``from_`` when used as an argument, since |
|
||||
| | ``from`` is a Python keyword. |
|
||||
+----------------------+------------------------------------------------------+
|
||||
| to | Float value. If set, this is the maximum value to |
|
||||
| | which the increment button will increment. |
|
||||
+----------------------+------------------------------------------------------+
|
||||
| increment | Float value. Specifies the amount which the |
|
||||
| | increment/decrement buttons change the |
|
||||
| | value. Defaults to 1.0. |
|
||||
+----------------------+------------------------------------------------------+
|
||||
| values | Sequence of string or float values. If specified, |
|
||||
| | the increment/decrement buttons will cycle through |
|
||||
| | the items in this sequence rather than incrementing |
|
||||
| | or decrementing numbers. |
|
||||
| | |
|
||||
+----------------------+------------------------------------------------------+
|
||||
| wrap | Boolean value. If ``True``, increment and decrement |
|
||||
| | buttons will cycle from the ``to`` value to the |
|
||||
| | ``from`` value or the ``from`` value to the ``to`` |
|
||||
| | value, respectively. |
|
||||
+----------------------+------------------------------------------------------+
|
||||
| format | String value. This specifies the format of numbers |
|
||||
| | set by the increment/decrement buttons. It must be |
|
||||
| | in the form "%W.Pf", where W is the padded width of |
|
||||
| | the value, P is the precision, and '%' and 'f' are |
|
||||
| | literal. |
|
||||
+----------------------+------------------------------------------------------+
|
||||
| command | Python callable. Will be called with no arguments |
|
||||
| | whenever either of the increment or decrement buttons|
|
||||
| | are pressed. |
|
||||
| | |
|
||||
+----------------------+------------------------------------------------------+
|
||||
|
||||
|
||||
Virtual events
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
The spinbox widget generates an **<<Increment>>** virtual event when the
|
||||
user presses <Up>, and a **<<Decrement>>** virtual event when the user
|
||||
presses <Down>.
|
||||
|
||||
ttk.Spinbox
|
||||
^^^^^^^^^^^^
|
||||
|
||||
.. class:: Spinbox
|
||||
|
||||
.. method:: get()
|
||||
|
||||
Returns the current value of the spinbox.
|
||||
|
||||
|
||||
.. method:: set(value)
|
||||
|
||||
Sets the value of the spinbox to *value*.
