Is there anybody out there who can explain the main difference between DECWindows and XWindows?? So far I have been able to note that DECWindows calls differ from XWindows calls in some functions, and that you can run XWindow-programs in a DECWindows environment, but not the other way. Am I right, or am I right? I have also seen a 'layer-description' of DECWindows that shows the relations between the layers DECWindow Toolbox Intrinsics, DECWindow Library etc, etc. Is there any corresponding for XWindows? No flames please! ;-) Thanks! +------------------------------------------------------------------------------ | Anders Ulfheden | USENET: ulfis@nada.kth.se | Royal Institute of Technology | Stockholm, Sweden

DECWindows -> Memory pig. Seen a uVax II with 9 meg and a good size swap space run i (can't remember how much). Even with only one terminal window (DECTerm), it couldn't start up some of the simple demo programs (runs out of swap space). X ain't the greatest, but it's a lot better than that. DECWindows is really slow too. See below for my problems with X. -Will Frank wf08+@andrew.cmu.edu "Lots of preferences are BAD not good. Most of the bad things that can be said of X have to do with all the homage paid to the holy cause of policy independence and allowing anyone to screw themselves with their preferences. Andrew has won through 'one user interface policy -- it works'. It's time the messages developers were reminded of that." -- Bill Cattey

DECwindows is the name of Digital's product version of X. It includes servers, Xlib, the Xt intrinsics, the XUI toolkit, and applications. >So far I have been able to note that DECWindows calls differ from XWindows >calls in some functions Nope. >, and that you can run XWindow-programs in a >DECWindows environment, but not the other way. Am I right, or am I right? You're not right. We run DECwindows applications on non-DEC servers all the time for interoperability testing. The only real problem is that some of the programs don't react very gracefully to not finding the fonts they want; we're working on this. -paul asente asente@decwrl.dec.com decwrl!asente
