I am going to do that full-install as soon as I can... I just got an Athlon 1700 w/ XP (arggh!) but it has a CD-burner...so I think I'll download the various JDKs for the various platforms and save them permanently, so I can install them quicker... I think I should take a few steps to extract the last AWT out of the mandatory section, and then stabilize the current AWT release of the GUI, and re-start the GUI development in Swing... There's nothing inherently wrong, though, in allowing for both, is there? There is something for one single standardized GUI...but I also had dreams for a drag-n-drop customizable GUI... I feel the best work in the product to date the user never sees... ~Dave David Scott Williams Computer Associates Marketing Representative-Sales Call Center One Computer Associates Plaza Islandia, New York 11749 tel: +1 800-243-9462 ext. 73431 tel: +1 631-342-3431 (Direct) fax: +1 631-342-5734 wi...@ca... -----Original Message----- From: Borne Goodman-Mace [mailto:bm...@eg...] Sent: Monday, December 17, 2001 1:58 PM To: Williams, David Subject: RE: [Cxtable-devel] Java on *nix How is your AWT doing now with the new linux install? I have downloaded and am playing with SkinLF (from l2fprod.com) which allows for a VERY niice and flexible look and feel system for Swing. You should check it out. The best add-on for UI flexibility for Java that I have seen yet. --bjgm On Thu, 2001-12-13 at 16:58, Williams, David wrote: > Did you ever notice that the words "robust" appeared in marketing letters at about the same time that Java appeared?

I did not know, after all, that I had Motif libraries, so I assume that they must have come w/ Java?... maybe the install failed and I should re-download it again? I dunno... I am in the process of installing Debian right now... the "Potato"... we'll see if that is any better... ;-) > > > > David Scott Williams > Computer Associates > Marketing Representative-Sales Call Center > One Computer Associates Plaza > Islandia, New York 11749 > tel: +1 800-243-9462 ext. 73431 > tel: +1 631-342-3431 (Direct) > fax: +1 631-342-5734 > wi...@ca... > > > > > > > -----Original Message----- > From: Borne Goodman-Mace [mailto:bm...@eg...] > Sent: Thursday, December 13, 2001 4:44 PM > To: cxt...@li... > Subject: Re: [Cxtable-devel] Java on *nix > > > Swing is based on the AWT foundation, so it will definitely be slower in > a lot of cases, but it gives a few important things that the AWT did not > have.

I would consider moving the application to Swing, as some of my most recent changes no longer run correctly under the last MVM release (their implementation of Java, jview..)... > > {{{ I don't, however, wish to debate that. I kept compliance w/ jview because a couple of my beta-testers (now they've become more intelligent) were REALLY poor at understanding these things, and they had Jview, and they DL'd the patch from microsoft...and I could test the program w/o impacting their daily software requirements greatly.....
