fpGUI
fpGUI is a Object Pascal toolkit for cross-platform application development. It provides single-source portability across Linux, MS Windows, *BSD, Solaris/OpenSolaris, ReactOS and embedded devices like Embedded Linux and Windows CE. fpGUI Toolkit can be used for Open Source and Commercial applications.
fpGUI is a widgetset completely written in Object Pascal. It links directly with the underlying windowing system (Xlib, GDI), and thus avoids the need for many large external libraries (eg: Qt, GTK etc). The main design goal is to get a consistent look and behavior across platforms.
