Class AbstractBooleanDataBinding

java.lang.Object

All Implemented Interfaces:

AbstractDataBinding<Boolean>

Direct Known Subclasses:

BooleanDataBinding, ContainerBooleanDataBinding

public abstract class AbstractBooleanDataBinding
extends Object
implements AbstractDataBinding<Boolean>

An abstract implementation of AbstractDataBinding for binding boolean values to SWT Button controls (typically used for checkboxes). This class handles the two-way synchronization between a boolean model value and an SWT checkbox widget.

The binding automatically:

• Updates the checkbox state when the model changes
• Updates the model when the checkbox is toggled by the user
• Prevents unnecessary updates when values haven't actually changed
