What are the functionalities of AWT in Java?
Java AWT (Abstract Window Toolkit) is a Java API used for building graphical user interfaces (GUI). It offers numerous features for creating components such as windows, buttons, and text fields, as well as handling user input events.
Here are some common features of Java AWT:
- Components: AWT provides many classes of components, such as Button, Label, and TextField, which are used to build user interfaces.
- Layout Managers: AWT offers multiple layout managers to automatically arrange the position and size of components, such as FlowLayout, BorderLayout, and more.
- Event handling: AWT offers an event model and listener interfaces to handle user input events, such as button clicks, mouse movements, etc. Specific events can be responded to by registering listeners.
- Graphics drawing: AWT provides the Graphics class for drawing graphics, text, etc. on a window. You can use the methods of the Graphics class to draw lines, rectangles, ellipses, and other shapes.
- Image processing: AWT offers the Image class and its related methods for loading, displaying, and manipulating images. Images can be loaded into a window and manipulated with functions like scaling and rotation.
- Multi-thread support: AWT offers thread-safe methods for updating the user interface in multi-threaded environments. You can use the methods of the EventQueue class to put tasks into the event queue, ensuring they are executed on the event dispatch thread.
- Clipboard support: AWT provides the Clipboard class and related methods for handling text and image data in the clipboard. Data can be copied to the clipboard or retrieved from the clipboard.
- Fonts and colors: AWT provides the Font class and Color class to select suitable fonts and colors for displaying text and graphics. You can set the font and color of components, as well as the font and color when drawing text.
These are just some common features of Java AWT, it also offers many other functionalities such as file selection dialogues, system trays, and printing support.
