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:

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)

SectionBrowser.select()

Syntax:

.select(sec=section)

Description:

specified section is highlighted.

Example:

from neuron import h, gui
soma = h.Section(name='soma')
axon = h.Section(name='axon')

sb = h.SectionBrowser()
sb.select(sec=axon)

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:

from neuron import h, gui
soma = h.Section(name='soma')
axon = h.Section(name='axon')

def select(sec):
    print(f'select: {sec} {type(sec)}')

def accept(sec):
    print(f'accept: {sec}')

sb = h.SectionBrowser()
sb.select_action(select)
sb.accept_action(accept)

Note

Python support for select_action() was added in NEURON 7.5.

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:

from neuron import h, gui
soma = h.Section(name='soma')
axon = h.Section(name='axon')

def select(sec):
    print(f'select: {sec} {type(sec)}')

def accept(sec):
    print(f'accept: {sec}')

sb = h.SectionBrowser()
sb.select_action(select)
sb.accept_action(accept)

Note

Python support for accept_action() was added in NEURON 7.5.
