For over a decade, Erlang's cross-platform GUI interface, wxErlang, has sat dormant without a meaningful & practical guide. This talk is wxErlang's long-awaited tutorial. As one of the first presentations on the subject, we have an opportunity to discuss best-practices surrounding the understandability & comparability of the code we shall ultimately write for each other. To do so, we draw on knowledge from the accounting profession, in particular Conceptual Statement 8 (CON 8). CON 8 is the central framework in the worldwide 'Harmonization' effort: principles set forth by the FASB¹ & IASB² to guide the internationalization of accounting standards. Whether you find this surprising or not, Accountants and Erlangers both deal with very similar issues; such as what, where, and when to log information, and in our case of WxErlang, how to ultimately present data to the user. From there we shall promptly delve into the gears of wxErlang. By the end of this talk, not only will you be able to craft a basic wxErlang application, but also be well equipped to participate in writing code that can help harmonize the community.
