The split ploint is calling the super.__init. Some functions need to be called before,
some after.
For example:
The about dialog is created in the template main window init. So we need to set additional
help texts before that init.
#Inject more help texts in the templates About "Did You Know" field.
#About.didYouKnow is a class variable.
#Make the first three words matter!
#Do not start them all with "You can..." or "...that you can", in response to the Did you know? title.
#We use injection into the class and not a parameter because this dialog gets shown by creating an object. We can't give the parameters when this is shown via the mainWindow menu.
