= What is the concept of a control?Baidu said that controls are the encapsulation of data and methods. The control can have its own properties and methods. A property is a simple visitor to the control's data.For HMI development, the use of controls can quickly get to the user's interaction (including press, release, click, drag, and so on), you can quickly apply the already encapsulated operational logic.= "Why encapsulate, use controls?"Designing co
