Chapter 13: Problem 20

What type of event do menu items generate when selected by the user?

Short Answer

Expert verified

Answer: An "ActionEvent" is generated by menu items when they are selected by a user in a graphical user interface (GUI).

Step by step solution

Identify the context of menu items

Menu items are typically part of a graphical user interface (GUI) in software applications. They can be seen in menu bars, context menus, or drop-down lists, and they allow the user to interact with the application by selecting an option or performing an action.

Understand the purpose of events

Events are generated by various user interactions with the GUI, such as clicking a button, selecting a menu item, or typing in a text box. Events help in capturing the user's actions so that the application can respond appropriately. An event listener is usually attached to the GUI component to handle the specific event.

Identify the event generated by menu items

When a user selects a menu item in a GUI, the event generated is commonly known as an "ActionEvent." ActionEvents are triggered by various user interface elements, like buttons and menu items, when they are activated or interacted with.

Examine event handling for ActionEvents

To handle an ActionEvent generated by a menu item, an event listener must be attached to the menu item. In Java, for example, this is done by implementing the ActionListener interface and overriding the actionPerformed(ActionEvent e) method. The actionPerformed method will be called when the user selects the menu item, allowing the application to perform any desired action in response.
