Signals are tailor-made to notify a single object about a certain event or change in the system. Each of the three different signal types can be sent in the Chora code to either a property of type 'slot' or to a 'slot method' e.g.:
If there is no slot method assigned to a slot property, the signals have no effect – neither a call of a method nor a runtime error occurs. Now let’s have a more detailed look on the different signal types.
For more information please have a look to Chora User Manual - chapters 'signal' statement, 'postsignal' statement and 'idlesignal' statement.
