    AniList Api v2 GraphQL Docs

    AniList Api v2 GraphQL Docs

    AniList API V2 GraphQL Documentation

    The AniList GraphQL Api provides quick and powerful access to over 500k anime and manga entries, including character, staff, and live airing data. The AniList & AniChart websites themselves run on the Api, so everything you can do on the sites, you can do via the Api. Free for non-commercial use. GraphQL is a strongly typed Api query language that provides an alternative to REST. It allows clients to define the structure of the data required, and exactly the same structure of the data is returned from the server. This avoids both the problems of over and under-fetching data, while also allowing for a more powerful and flexible Api. You can omit the variables object and instead hard-code your values inside your query, however, this is not recommended past the simplest of queries.

    This is a tutorial about how to create a video player. This tutorial pretends to be a brief introduction to the Graphics User Interfaces (GUI) programming, using the Python programming lenguage and Qt framework, both multiplataform. In this tutorial we'll use PyQt to show you the base of Qt programming under Pyhon. To make this tutorial even more funny, because you can learn the theorical side of Qt programming just reading the documentation, I will focus it only in the practical side, therefore I deside to show you how to create a video player, which its programming is unbelievably simple with Qt. Topics ==== - Useful programming IDEs and tools. - Using Qt Designer for quick GUI design. - Using signals and slots. - Using basic widgets. - Using timers. - Using Phonon multimedia framework. - Using list widgets. - Using stylesheets.
