What does setOnMouseEntered() handle?

Question

BlackTom AI · Accepted Answer

Question restatement: The prompt asks, 'What does setOnMouseEntered() handle?' and provides five options to choose from.
Option a: 'When clicked' — This describes handling a mouse click event, not a mouse entry. setOnMouseClicked would be the handler for clicks, so this is incorrect.
Option b: 'When mouse exits' — This corresponds to a mouse exit event, typically handled by setOnMouseExited, so this option is not what setOnMouseEntered handles.
Option c: 'When node loaded' — Node loading occurs during initialization or when a scene graph is built, not tied to mouse entry events; thus this is false.
Option d: 'When double-clicked' — A double-click is a specific form of clicking event and would be handled by a dedicated handler like setOnMouseClicked with care for click count; setOnMouseEntered is not about double-clicks, so this is incorrect.
Option e: 'When mouse enters the node’s bounds' — This precisely describes the mouse enter event: the pointer crosses into the rendered area of the node, triggering the entered-state handler. This matches the intended behavior of setOnMouseEntered.
Overall, each distractor targets a different event concept (click, exit, load, double-click) or a misinterpretation of event timing, while the correct understanding aligns with the mouse entering the node’s bounds.
