TODO:
- create a generic Widget struct
- create a generic callback function
- create an enum of all widgets and pass it as a parameter to the callback
so there can be only 1 callback for all the widgets - actually I can figure
this out from the magic bytes of the widget, but the enum still would be 
nice to exist for some reason yet unknown.
