= 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

study it.to show the core function straight to the point. The following methods are used to achieve:n reduce the control to make the user choosen reasonable use of standard controls and gestures, and attention to consistencyn the label of the control needs to be clear, so that users can clearly know what they are doingConsistent with the usage specifications used by the built-in application. The user knows how to navigate between screens with hierarchical relationships, edit the contents of the
older computers and assistive devices.
To ensure that anyone can operate products: people with disabilities, the elderly, low-level literacy and so on.
Consistency
The same application uses similar layouts and terminology.
Use user-familiar interaction and navigation methods.
Ensure consistency between user interface and usage context.
Feedback
Provide timely feedback.

Recently I have worked with my colleagues to develop a multi-process software. My colleagues write HMI (Interface) processes and I write COMM (Communication) processes. HMI provides read/write interfaces for shared memory. Both COMM and HMI use this interface to write the shared memory.
My COMM project needs to use interface functions provided by the
