It wrapps low level x11/win32 calls into a usable frameworks called fpGUI Object orientation is often a wrapper around system calls, fpGUI is object oriented and makes low level calls so someone can use fpGUI as a wrapper around these obnoxious insane low level calls that no one wants to use directly. -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus-ide.org http://lists.lazarus-ide.org/listinfo/lazarus
