Action activation triggering API demo

Activate actions in the current control of a window.

Action activation works both in direct and socket APIs but querying the lists of available action methods is only available in direct mode.

import anatomist.direct.api as anatomist
from soma.qt_gui.qt_backend import Qt
import sys

runloop = False
if Qt.QApplication.instance() is None:
    runloop = True

a = anatomist.Anatomist()

vol = a.loadObject('irm.ima')
w = a.createWindow('Axial')
w.addObjects(vol)

w.activateAction(action_type='key_press', method='movie_start_stop')
# set backward movie mode
w.activateAction(action_type='key_press', method='movie_next_mode')
# loop forward
w.activateAction(action_type='key_press', method='movie_next_mode')
# loop backward
w.activateAction(action_type='key_press', method='movie_next_mode')
# loop both ways
w.activateAction(action_type='key_press', method='movie_next_mode')

# query available actions methods
c = w.view().controlSwitch().activeControlInstance()
print('in control:', c.name())
kpmethods = c.keyPressActionLinkNames()
print('* keyPress methods:', kpmethods)
mpmethods = c.mousePressActionLinkNames()
print('* mousePress methods:', mpmethods)

w.setControl('SelectionControl')
c = w.view().controlSwitch().activeControlInstance()
print('in control:', c.name())
kpmethods = c.keyPressActionLinkNames()
print('* keyPress methods:', kpmethods)
mpmethods = c.mousePressActionLinkNames()
print('* mousePress methods:', mpmethods)

if runloop:  # and 'sphinx_gallery' not in sys.modules:
    Qt.QApplication.instance().exec_()
if runloop or 'sphinx_gallery' in sys.modules:
    del c, w, vol, kpmethods, mpmethods
