Package org.eclipse.swt.widgets
Class Synchronizer
java.lang.Object
org.eclipse.swt.widgets.Synchronizer
- Direct Known Subclasses:
UISynchronizer
Instances of this class provide synchronization support
for displays. A default instance is created automatically
for each display, and this instance is sufficient for almost
all applications.
IMPORTANT: Typical application code never needs to deal with this class. It is provided only to allow applications which require non-standard synchronization behavior to plug in the support they require. Subclasses which override the methods in this class must ensure that the superclass methods are invoked in their implementations
