Primitives & Utils
Internally, every GUI component are based off a GUIElement
class. Not much is to be said about it, but please refer to its original SDK Code if you need to extends them.
The C++ classes wrap their C call to make them easier to use using virtual tables, as shown in the SDK.
It is thought that internally the GUI is based on an older version of PEG - Portable Embded GUI, that is now NXP proprietary.
