UnRegisterUserEvent Method
The UnRegisterUserEvent method removes a frame's registration for a specified event or for all events.
This method has the following syntax:
GhostExec.UnRegisterUserEvent([eventname = varchar(32)])
Note: The parentheses are required even if you do not specify an event name.
This method has the following parameter:
eventname
Specifies the event whose registration you want to remove. The parameter is case-sensitive. If you do not specify an event name, OpenROAD unregisters all user events for that frame.
