Change the value of EXAMPLE_COMPLEXITY in the first line to change the behavior :
- 0 : prints "Hello World!" in the Info and console widgets
- 1 : pops-up a simple dialog asking to enter an integer , then prints it in the Info and console widgets
- 2 : pops-up a little more elaborated dialog asking to enter an integer , then prints it in the Info and console widgets if it was indeed an integer, else pops-up an error message box.
