What is required to change SWT widget properties not set by the constructor?

Reconstruction of the widget
Setter methods
Direct property access
Restarting the application

The correct answer is: Reconstruction of the widget

To change SWT widget properties not set by the constructor, it is necessary to reconstruct the widget. This means creating a new instance of the widget with the desired property changes. Option C, direct property access, may work for other types of widgets, but it is not possible with SWT widgets. Option B, using setter methods, is also not possible as most SWT widgets do not have setter methods for their properties. Option D, restarting the application, does not change the properties of the widget and is not a viable option.
