All text information is saved to a log_file.txt file, located in the project folder. There, you will also find up to three new sample images, generated each time a new circle is created or its color is modified within the application.

Hints:

To use the Change Logger control, it is necessary to:

drag and drop it into the HMI designer,
enable the changes for particular actions to be logged using the control properties,
select appropriate values for the properties to determine the control's behavior.

You can decide whether you want to log:

the changes in the program state (pausing, running, etc.),
the changes in the HMI,

as well as whether you want the records to be logged:

directly to the console,
or directly to a specific file path
