The binary version of XPCE runs on Windows NT, 2000 and XP.15As of 6.5.x, XPCE is a UNICODE application and is no longer supported for Windows 95, 98 and ME. Its functionality is very close to the Unix/X11 version, making applications source-code compatible between the two platforms. .
XPCE does not build on top of the hosting window-systems GUI library. Instead, the primitive windowing and graphics facilities of the host are used to implement `XPCE's Virtual Window System'. All of XPCE's graphical functionality is build on top of this `Virtual Window System'. This approach guarantees full portability of applications between the platforms.
The look-and-feel of XPCE may be tailored using
the defaults file located in <pcehome>/Defaults.
