Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 12]

Nbugui
Ccolor	Generic colour class holding RGBA coloour values. The blinking and pulsing states indicate discrete or smooth cycling between the LED lit with the specified colour, and the LED turned off (set to black)
Cbase_converter	Provides base functionalities for converting color objects to devices specific colour values
Ccolor_converter	Povides convertion of color objects to device specific integer values
Ccolor_converter< T, color::rgba >	Basic wrapper for devices supporting RGBA colours
Ccolor_converter< T, uint8_t >	Converts color objects for grayscal only devices
Cpalette	Provides access to the device's colour palette
Cpalette< T >	Provides access to the device's colour palette and converts it from HEX to RGB values
Cbase_controller	Serves as the root of the widget tree. Also provides access to buttons componnents
Ccontroller	Main class to inherit from. Acts ast the root of the widget tree, and provides generic access to the hardware through the painter and presser objects
Cctrlr_deleter	Ensures that buttons labeled Delete triggers the delete funcitonlaity on the widget tree, even if on_Delete is not defined by the user
Cctrlr_deleter< T >	Basic wrapper to handle user defined on_Delete funtction
Cctrlr_shifter	Ensures that buttons labeled Shift are registered on press and can be queried with Shift_held, event if on_Shift is not defined by the user
Cctrlr_shifter< T >	Basic wrapper to handle user defined on_Shift function
Cpoint	Provides the basics of 2D geometry. Primarily used as the top left and bottom right corners of the rectangle class
Crectangle	Provides the geometric structure of widgets
Cbase_hardware	Provides base functionalities of the hardware object, and enables access from the base_controller
Chardware	Inherits from all type of hardware components like grid, buttons... Provides the hardware type with the functionalities to interact with each components
Ccommon	Inherits from all type of hardware components like grid, buttons... Provides the hardware type with the functionalities to interact with each components
Cbuttons	Empty struct for devices that do not feature labelled buttons
Cbuttons< Device, Controller >	Handles presses and enables painting on the device's labelled buttons
Cclear	Empty struct for devices or componants that do not provide a command to clear all feedback (LED's, sceen...)
Cclear< Device >	Enables calling the device's 'clear' command if it provides one
Cclear< Component >	Enables calling the 'clear' command of a specific component on the device, if one is featued
Cgrid	Empty struct for devices that do not feature a button grid
Cgrid< Device, Controller >	Handle presses and enables painting on the device's button grid
Cinit	Empty struct for devices that do not provide an initialisation command
Cinit< Device >	Enables calling the device's 'init' command if it provides one
Cinit< Component >	Enables calling the 'init' command of a specific component on the device, if one is featued
Chardware_factory	Instantiate a hardware object specialised with a specific device
Cmidi	Empty struct for devices that do not support MIDI
Cmidi< Component >	Allows for sending and receiving MIDI messages
Cmidi_common	Holds MIDI port objects for access by derived classes. It also enables components to register their callback funcitons
Csysex_formater	Provides funcitons to retrieve the prefix size for a specific componenet's SYSEX messages. The SYSEX prefix is usually comprised of a specific device number and manufacturer's ID
Cbase_midi_formater	Provides underlying functionalities to format and store MIDI messages, before applying blinking or pulsing effects
Cmidi_formater	Empty enum for devices that do not feature anny blinking or pulsing functionalities
Cdual_blinker	Enables the use of multiple buffers targetting diferent midi Channels. This method is used for devices and components expecting MIDI messages on 2 diffrent channels to blink LED's
Cmidi_formater< Component >	Provides necesary functionalities to format and store MIDI messages. A Blinking effect can also be applied by storing a color value in a diferent MIDI buffer, to be sent to the dedicated channel
Cdual_pulser	Enables the use of multiple buffers targetting diferent midi Channels. This method is used for devices and components expecting MIDI messages on 2 diffrent channels to pulse LED's
Cprotocol	Inherits from different protocols, depending on the device's specification
Cbase_painter	Holds a color object and provides the relevant setters
Cbutton_painter	Conveys button colors from the controller to the base_hardware
Cbutton_presser	Provides a generic interface to represent a button press event by the user on the device
Cpainter	Adds 2D information on top of a base_painter. The painter is used in user defined paint funcions to draw on the device. Meant to traverse the entire widget tree, each widget temporarly applies a coordinate offset to the painter, reflecting their relative position in the scene
Cpresser	Adds 2D information on top of a button_presser. Meant to traverse the entire widget tree, each widget temporarly applies a coordinate offset to the paresser, reflecting their relative position in the scene
Ccolor_t	Primary template for a Device and a Component that do not feature a color nested type
Ccolor_t< Device, Component >	Provides a type alias for the nested color type of the Device, only if the Component does not also feature a nested color type
Cprotocol_t	Primary template providing a type alias for the Device only if the Component type does not feature a protocol declaration
Cprotocol_t< Device, Component >	Provides a type alias for a Component featuring a prtocol declaration
Cclear_t	Primary template. To be specialized
Cclear_t< Device, Component >	Provides a type alias for the clear nested type of the Device, only if the Component type does not also feature a clear nested type
Cinit_t	Provides a type alias for the init nested type of the Component
Cinit_t< Device, Component >	Provides a type alias for the init nested type of the Device, only if the Component does not also feature an init nested type
Ccomponent	Primary template. To be specialized
