The add_actions() method is a convenience method that creates a number
of gtk.Action objects based on the information in the list of action
entry tuples contained in entries and adds them to the action group.
The entry tuples can vary in size from one to six items with the
following information:
* The name of the action. Must be specified.
* The stock id for the action. Optional with a default value of None
if a label is specified.
* The label for the action. This field should typically be marked
for translation, see the set_translation_domain() method. Optional
with a default value of None if a stock id is specified.
* The accelerator for the action, in the format understood by the
gtk.accelerator_parse() function. Optional with a default value of
None.
* The tooltip for the action. This field should typically be marked
for translation, see the set_translation_domain() method. Optional
with a default value of None.
* The callback function invoked when the action is activated.
Optional with a default value of None.
The "activate" signals of the actions are connected to the callbacks and
their accel paths are set to /group-name/action-name.

The add_toggle_actions() method is a convenience method that creates a
number of gtk.ToggleAction objects based on the information in the list
of action entry tuples contained in entries and adds them to the action
group. The toggle action entry tuples can vary in size from one to seven
items with the following information:
* The name of the action. Must be specified.
* The stock id for the action. Optional with a default value of None
if a label is specified.
* The label for the action. This field should typically be marked
for translation, see the set_translation_domain() method. Optional
with a default value of None if a stock id is specified.
* The accelerator for the action, in the format understood by the
gtk.accelerator_parse() function. Optional with a default value of

* The tooltip for the action. This field should typically be marked
for translation, see the set_translation_domain() method. Optional
with a default value of None.
* The callback function invoked when the action is activated.
Optional with a default value of None.
* A flag indicating whether the toggle action is active. Optional
with a default value of False.
The "activate" signals of the actions are connected to the callbacks and
their accel paths are set to /group-name/action-name.

The add_radio_actions() method is a convenience method that creates a
number of gtk.RadioAction objects based on the information in the list
of action entry tuples contained in entries and adds them to the action
group. The entry tuples can vary in size from one to six items with the
following information:
* The name of the action. Must be specified.
* The stock id for the action. Optional with a default value of None
if a label is specified.
* The label for the action. This field should typically be marked
for translation, see the set_translation_domain() method. Optional
with a default value of None if a stock id is specified.
* The accelerator for the action, in the format understood by the
gtk.accelerator_parse() function. Optional with a default value of
None.
* The tooltip for the action. This field should typically be marked
for translation, see the set_translation_domain() method. Optional
with a default value of None.
* The value to set on the radio action. Optional with a default
value of 0. Should be specified in applications.
The value parameter specifies the radio action that should be set
active. The "changed" signal of the first radio action is connected to
the on_change callback (if specified and not None) and the accel paths
of the actions are set to /group-name/action-name.

The add_buttons() method adds several buttons to the Gtk.Dialog using
the button data passed as arguments to the method. This method is the
same as calling the Gtk.Dialog.add_button() repeatedly. The button data
pairs - button text (or stock ID) and a response ID integer are passed
individually. For example:
.. code-block:: python
dialog.add_buttons(Gtk.STOCK_OPEN, 42, "Close", Gtk.ResponseType.CLOSE)
will add "Open" and "Close" buttons to dialog.

:param str tag_name:
Name of the new tag, or None
:param **properties:
Keyword list of properties and their values
This is equivalent to creating a Gtk.TextTag and then adding the
tag to the buffer's tag table. The returned tag is owned by
the buffer's tag table.
If ``tag_name`` is None, the tag is anonymous.
If ``tag_name`` is not None, a tag called ``tag_name`` must not already
exist in the tag table for this buffer.
Properties are passed as a keyword list of names and values (e.g.
foreground='DodgerBlue', weight=Pango.Weight.BOLD)
:returns:
A new tag.
