Overview ¶
Example:This a GUI application in Go.
The main function is the entry point of the program. It initializes a connection to the Teonet network and Teofortune service, and then launches the graphical user interface (GUI).
It first tries to connect to Teonet and Teofortune by calling newTeofortune, passing the application name and Teofortune address. newTeofortune returns a teofortune object that contains the Teonet client and Teofortune API client. If there is an error connecting, it prints the error and exits the program.
If the connection is successful, it calls the newGui method on the teofortune object. This will create and display the GUI window.
The main purpose of main is to initialize the networking connections and launch the user interface. It takes no direct inputs. Its output is to start up the GUI application.
It achieves this by first initializing the back-end networking using newTeofortune. This sets up the ability to connect to Teonet and Teofortune. Once that is done, it launches the front-end GUI by calling newGui.
The main logic flow is:
- Initialize networking - If no errors, launch GUI - If errors, print error and exit
So in summary, main handles setting up the app and starting it up, delegating the specific networking and GUI code to other functions. This is a common structure for main functions - initialize, then launch.
