SWT – the Standard Widget Toolkit
SWT is the widget toolkit used by Eclipse that gives performant access to the platform's native tools in a portable manner. Unlike Swing, which is rendered with Java native drawing operations, SWT delegates the drawing to the underlying operating system.
In this chapter we will:
- Create an Eclipse view with SWT widgets
- Create a custom SWT widget
- Work with SWT resources and learn how to detect and fix resource leaks
- Handle focus operations
- Group components and resize them automatically
- Create system tray items
- Display nonrectangular windows
- Provide scrolling and tabbed navigation
