Can you present a concrete exanple of such a difference in > abstractions? For example, programs in GTK+ aren't supposed to create windows or widgets manually anymore. Instead, GTK provides a system to create "applications", which run in the background and respond to requests to open files or to display a default window, and it also provides an XML-based format for describing the layout of widgets and windows. In GTK 4, menus cannot even be modified by applications on-the-fly anymore. You are again supposed to use a GTK-specific XML format to describe the menus of your application in a way that cannot be changed at run-time. What used to be a few ifdefs (and some code) away now requires you to write a different XML file for each toolkit, and to redesign your application to fit various unnecessary limitations imposed by the toolkit developers. > Would it be possible to invent a higher-level abstraction to unify > these toolkits? I'm not sure.
