Structure
Here we provide a high level documentation of pyglui classes and elements.
The UI class is a user interface context that must be created within a system window. We have designed pyglui to be used with glfw, but it should also work with other window managers.
It is a manager of ui elements and the top level control layer of the UI.
UI elements can be appended to the UI context just like how you would interact with a normal list in Python. For example you can append a new menu element to the ui with ui.append(menu), extend the ui with ui.extend or remove elements with ui.remove.
Since the UI class has access to all elements, it can also globally control attributes like scale - so that you can increase or decrease the size of each UI element with ui.scale.
The FitBox is the key building block...or box...of pyglui. It is used in almost every class to define a two dimensional rectangular context or 'box'. A FitBox is defined by two 2D vectors, position (x,y) and size (width,height), and fits itself into a context (hence the name fit + box). Typically the context is defined by another 'parent' FitBox, except for the case of the UI class where the context is the window created by glfw itself. We'll demonstrate this a bit later.
The position and size vectors of the FitBox class define how it fits into its parent context. We have prepared a few diagrams to help clarify the rules.
