The specific application of the component, what are the design components

1. Definitions. Also known as component-oriented programming.

It is expressed through methods like abstracting, decomposing, iterating, and refining them. The key to this is the decomposition technique--- which breaks down a large question book into smaller, manageable units so that each unit can be handled individually. This technique is at the heart of many approaches to software engineering.

These approaches can be referred to as structured design, modular programming, or object-oriented, and the units they produce are called modules, packages, or building blocks. State matching.

2. Role. A widget is a self-published feature that can access its services through its interface.

Components, also known as controls, are reusable cells of the user interface that enable the ability to quickly create complex applications without the user being exposed to software rather than coding. The main components include:1

List Box: The list box allows the Sell Slider to select one or more entries from a predefined list. 3.

Text box: A text box is used to enter text, such as a username, password, or any text. 4.

Checkbox: A checkbox allows the user to select one or more options from multiple options. 5.

Radio buttons: Radio buttons allow users to select only one option out of multiple options. 6.

Slider: The slider is used to control and display a range of values, such as volume, brightness, and so on. 7.

Scrollbar: A scrollbar allows users to scroll through a page or document to access hidden content. 8.

Tabs: Tabs allow users to switch between different Zhongshenla tab pages to access different information. 9.

Collapse Window: A visual tool for collapsing page content, allowing users to navigate through long texts faster. 10.

Menus: Menus allow users to choose from available options, such as file menus or menus.

Components have the following meanings:

1.A combination of parts for assembling an entire machine, component, or component.

2.A set of elements assembled together in an electronic or mechanical device to form a functional unit.

3.The more or less repetitive parts that are often put together when assembling a product, such as a bookcase or cupboard.

4.One of several parts that can be assembled or reassembled.

Carnegie Mellon University:

An opaque functional entity that can be assembled by a third party and conforms to a component model.

Computer Encyclopedia:

It is a software entity in a software system that has relatively independent functions, interfaces are specified by contracts, and have obvious dependencies on the context, and can be deployed and assembled independently.

Software Component Works:

is an assembly unit with conventionally specified, standardized interfaces, and explicit dependencies. Builds can be deployed independently and assembled by third parties.
