Eseménykezelkre

Eseménykezelkre, a Hungarian term, translates to "event handling" in English. It refers to the process of detecting and responding to occurrences, known as events, within a computer system or application. These events can be triggered by various sources, including user interactions such as mouse clicks or keyboard input, system-level occurrences like file system changes or network messages, or internal program logic.

In software development, event handling is a fundamental concept. When an event occurs, the system or application needs a mechanism to capture it and execute a specific piece of code, often called an event handler or event listener, in response. This handler is designed to perform a predefined action based on the nature of the event. For instance, a button click event might trigger a function to display a message or navigate to a different page.

The architecture of event handling typically involves an event loop that continuously monitors for incoming events. Upon detection, the event loop dispatches the event to the appropriate handler. This asynchronous nature allows applications to remain responsive while performing tasks. Different programming languages and frameworks provide diverse ways to implement event handling, often utilizing callback functions or dedicated event objects. Effective event handling is crucial for creating interactive, dynamic, and user-friendly software.
