Implementation of SWT menu, toolbar, and coolbar

This article mainly implements menu, toolbar and coolbar, which are commonly used in the interface, compared with the previous simple controls, these controls are more flexible and difficult to use.

Menu implements many common types, such as single choice, check menu, and right-click menu. toolbar implements single choice, check, and drop-down, while coolbar is a flexible control, you can place controls on them and drag them as needed.
