The display of the Event Viewer can be controlled by changing the Show Event Viewer setting in the drawing’s Ambient Settings.
The Event Viewer is a Panorama vista. Each drawing can have a different Event Viewer session associated with it. When you change the active drawing, the Event Viewer session changes. If you do not activate the Event Viewer for a drawing, the Event Viewer is not displayed when that drawing becomes active. For information about Panorama vistas, see About the Panorama Window.
The Event Viewer displays the event tree in the left pane and the event list in the right pane.
You use the event tree to control the events that are listed in the event list. For example, if you click the top collection in the tree, Event Viewer, all events are listed in the event list. If you expand the event tree and click either the Event Subsystem collection or Surfaces collection, only the events that were logged by either the Event Subsystem (which is the Event Viewer) or the Surfaces feature are listed in the event list.
When you first open the Event Viewer, the event list is empty if no events have been logged to the Event Viewer. When an event is logged to the Event Viewer, the appropriate collection is created, and the event is added to the event list.
You can save the event list to a log file as a permanent record, and open a previously created log file to view it in the Event Viewer. You can also export an event list to a comma-delimited or tab-delimited text file.
You can control the content and appearance of the Event Viewer, including the columns displayed in the event list and the events listed there.
