What does setOnMouseClicked replace?

Question

BlackTom AI · Accepted Answer

When evaluating what setOnMouseClicked does, it helps to recall how event handlers are managed. 
Option a: 'Adds to all existing handlers' would describe an additive approach, which is not how setOnMouseClicked behaves—this method replaces, not adds, a handler. 
Option b: 'Deletes event type' is inaccurate because setOnMouseClicked is concerned with the handler for the mouse clicked event, not with deleting the event type itself. 
Option c: 'Replaces the previous click handler' correctly describes the purpose of setOnMouseClicked: it assigns a new handler and overrides any handler that was previously set for the mouse click event. This is the expected behavior when you want to replace the existing action with a new one. 
Option d: 'Removes all filters' is off-topic; mouse clicked handling is not about filtering, so this is not correct. 
Option e: 'Adds duplicate handlers' would imply creating multiple identical handlers, which setOnMouseClicked does not do; it replaces, not duplicates. 
In summary, among the choices, only option c accurately matches the function of setOnMouseClicked, while the others describe behaviors that either do not apply to event handling or describe opposite or incorrect effects.
