LogViewer

All Implemented Interfaces:

Localized

public class LogViewer
extends Widget

Shows a table of recent log records, optionally filtered to logs related to a specific resource. By default, Log­Viewer does not show any log entry. For viewing logs, one of the two following actions must be done:

• Set source to a non-null Resource value.
• Set system­Logs to true.

When a Resource value is specified, Log­Viewer shows only some logs that occurred while using that resource, in particular warnings emitted by the resource.
