Example of a user defined runnable subclass. Method Run() _must_ be implemented. Methods ThreadCatch and UnexpectedCatch _can_ be overridden to change default exception behaviour. This runnable is able to do different actions depending on the fiMode parameter set in the ctor (good for easy testing). However, the usual way is to create a dedicated runnable class for a dedicated purpose and pass different runnable classes to the different go4 threads (see Go4TaskHandler package for examples).
Different actions in this runnable: fiMode=0: Dummy printout a message every 5 seconds. fiMode=1: Kill and create sleep 30s, then kill other threads- sleep 5s, then create other threads again fiMode=2: Stop and start sleep 10s, then stop other threads- sleep 10s, then start other threads again fiMode=3: Aborting all sleep 30s, then abort application by means of exception fiMode=4: Histogramming creates histogram, fills it with random gaussian and draws it on pad depending on the runnable name ("Maker1", "Maker2"), different pads are used Maker 1 deletes histogram again each time, Maker 2 keeps initial histogram sleeps of 2s are used to slow down the action fiMode=5: Recreator Cancel and recreate one thread by name ("First Thread") every 15 s. fiMode=6: Exception tester sleep 60s, then throw different thread exceptions (latest: Restart exception) fiMode=7: Histogram without drawing create histogram, fill it with random and delete it again for memory alloc tests independent from root gui fiMode default: Undefined throw logic exception
NOTE1: Members of the runnable (histogram, canvas) are not deleted when the TThread is killed. The runnable exists independent from the thread. NOTE2: The user just has to create own runnables and a threadmanager subclasses, subclassing of TGo4Thread or other parts of the package are not required!
