.. _secbrows:
SectionBrowser
--------------
.. class:: SectionBrowser
Syntax:
``sb = h.SectionBrowser()``
``sb = h.SectionBrowser(SectionList)``
Description:
Class that makes a visible list of all section names.
If the optional SectionList arg is present then only those
section names are shown in the browser.
Example:
.. code-block::
python
from neuron import h, gui
soma = h.Section(name='soma')
dend = h.Section(name='dend')
sl = h.SectionList([soma]) # only the soma will be shown
sb = h.SectionBrowser(sl)
.. image:: ../../images/secbrows-sectionList.png
:align: center
.. seealso::
:class:`SectionList`, :ref:`stdrun_shape`
----
.. method:: SectionBrowser.select
Syntax:
``.select(sec=section)``
Description:
specified section is highlighted.
Example:
.. code-block::
python
from neuron import h, gui
soma = h.Section(name='soma')
axon = h.Section(name='axon')
sb = h.SectionBrowser()
sb.select(sec=axon)
.. image:: ../../images/secbrows-select.png
:align: center
----
.. method:: SectionBrowser.select_action
Syntax:
``sb.select_action(python_func)``
Description:
A Python function is executed when an item is selected (single click or
dragging) by the mouse. Before execution, the selected section
is pushed. (and popped after the function completes.)
A Python function is executed in the object context in which \ ``select_action``
registered it.
Example:
.. code-block::
python
from neuron import h, gui
soma = h.Section(name='soma')
axon = h.Section(name='axon')
def select(sec):
print('select: {} {}'.format(sec, type(sec)))
def accept(sec):
print('accept: {}'.format(sec))
sb = h.SectionBrowser()
sb.select_action(select)
sb.accept_action(accept)
.. note::
Python support for :meth:`select_action` was added in NEURON 7.5.
----
.. method:: SectionBrowser.accept_action
Syntax:
``sb.accept_action(python_func)``
Description:
A Python function is executed when an item is accepted (double click) by
the mouse. Before execution, the selected section
is pushed. (and popped after the function completes.)
A Python function is executed in the object context in which the ``accept_action``
registered it.
Example:
.. code-block::
python
from neuron import h, gui
soma = h.Section(name='soma')
axon = h.Section(name='axon')
def select(sec):
print('select: {} {}'.format(sec, type(sec)))
def accept(sec):
print('accept: {}'.format(sec))
sb = h.SectionBrowser()
sb.select_action(select)
sb.accept_action(accept)
.. note::
Python support for :meth:`accept_action` was added in NEURON 7.5.
