Method Detail

isCeased

boolean isCeased()

Returns whether it is ceased.

The event processing thread is ceased automatically. If you want to cease it manually, you can invoke DesktopCtrl.ceaseSuspendedThread(org.zkoss.zk.ui.sys.EventProcessingThread, java.lang.String).

An event processing thread is ceased if DesktopCtrl.ceaseSuspendedThread(org.zkoss.zk.ui.sys.EventProcessingThread, java.lang.String) was called manually, or if it is dead (Thread.isAlive() returns false). That is, it returns true if it is going to die, or dead already.

isSuspended

boolean isSuspended()

Returns whether it is suspended.

getEvent
