Logging Domains

CONFIGAnything related to the configuration of the Gantt chart control. For example: the renderers that are being registered for different activity types.
DNDDisplays everything related to a drag and drop operation (native drag and drop / platform provided drag and drop).
EDITINGReports changes to the start time, end time, percentage complete, chart value, of an activity.

Configuration File

The following file can be used to configure logging for FlexGanttFX.

# To use this property file add the following command line argument:
#    -Djava.util.logging.config.file=${project_loc}/log.properties
# Specify the handlers to create in the root logger
# (all loggers are children of the root logger)
# The following creates two handlers
# handlers = java.util.logging.ConsoleHandler, java.util.logging.FileHandler

handlers = java.util.logging.ConsoleHandler

# Set the default logging level for the root logger
.level = INFO

# Set the default logging level for new ConsoleHandler instances
java.util.logging.ConsoleHandler.level = OFF

# Set the default logging level for new FileHandler instances
# java.util.logging.FileHandler.level = ALL

# Set the default formatter for new ConsoleHandler instances
java.util.logging.ConsoleHandler.formatter = com.flexganttfx.core.LoggingFormatter
