In the SWT version of the ColorBoxes program, what SWT class is used that is similar to a JPanel in Swing?

Canvas
Composite
CBox
Shell

The correct answer is: Composite

The reason why A and C are incorrect is that the Canvas class in SWT is similar to the Canvas class in AWT, not the JPanel class in Swing. The Canvas class allows for low-level drawing operations while the JPanel class provides a simple container for other components. The CBox class does not exist in SWT. The Shell class in SWT is similar to the JFrame class in Swing, providing the main window for the application. However, it is not used in the same way as a JPanel, as it does not contain other components but instead is the top-level container for the GUI. Therefore, D is also incorrect. The correct answer is B because the Composite class in SWT is used as a container for other components, similar to the JPanel class in Swing. It allows for layout management and contains other widgets or controls. This makes it the closest equivalent to a JPanel in the SWT
