CellEventActions

CellEventActions

is an option for Cell that gives a list of actions to perform when specified events occur in connection with a cell in a notebook.

Details

  • CellEventActions->{"event1":>action1,"event2":>action2,…} specifies that actioni should be evaluated whenever "eventi" occurs in connection with a cell.
  • The possible event specifications are the same as for EventHandler.
  • Settings for CellEventActions are often defined at the level of stylesheets, rather than for individual cells or notebooks.
  • By default, any action specified for an event by CellEventActions will override any default action that the Wolfram System would take for that event.
  • The default behavior can be changed by including rules for PassEventsDown or PassEventsUp in the list given as the setting for CellEventActions.
