Snippet

Button Snippet

Demonstrates different types of SWT buttons including push, toggle, and check buttons.

This example creates a shell with three different button types arranged vertically:

  • Push button: Standard clickable button

  • Toggle button: Button that maintains pressed/unpressed state

  • Check button: Checkbox with text label

Each button prints a message to the console when clicked.
