You should be using the inbox/outbox interface, not these methods (except construction). This documentation is designed as a roadmap as to their functionalilty for maintainers and new component developers.

initPygame(self, **argd)

requests a display surface from the PygameDisplay service, fills the color in, and copies it


Main loop


Checks for control messages

update(self, text)

Updates text to the bottom of the screen while scrolling old text upwards. Delegates most of the work to updateLine

updateLine(self, line)

Updates one line of text to bottom of screen, scrolling old text upwards.
