  *            SunOS devGUIDE and Apple Macintosh MacX                 *
  *--------------------------------------------------------------------*/

 I am new to posting news so please excuse any lapses in proper etiquette.

 I am working to develop X based applications on SunOS using devGUIDE 1.1. 
 I will be moving to devGUIDE 3.0 when we get our copy.  The applications
 I develop will have to run on Sun's and display via X Server
 software on Mac's and PC's in both Color and Black and White modes.

 I am having difficulties getting my Open Look and Feel (thanks devGUIDE :-))
 X application to run as expected on my Mac IIfx (MacOS System 7.0) with the
 MacX server (version 1.1.7). My Mac has 20Mb of RAM and 4MB has been allocated 
 to run MacX.  I am running Sun's olwm as the Window Manager in MacX (this
 seems to work OK) so I can get all of the look and feel of Open Look. All
 client applications are displayed in a Color-Rooted MacX window.

 The 2 major problems I'm having deal with color differences and the physical
 size of the GUI on the Mac screen.

 /*----------------*
  *    Problem #1  *
  *----------------*/

 First, the physical size differences.  It seems that when my application 
 displays on the Mac (under MacX and the olwm) it's GUI is physically larger
 than when it displays on my Sun IPC.  I suspect this has to do with the
 differences in resolution of the 2 monitors.  The monitor on my IPC is a
 standard Sony 16" Color and the monitor on my Mac is an E-Machines 16" Color
 (1 Page).  Both machines are running 8 bit color (256 colors).  This problem
 is quite annoying and has got me puzzled.  Any thoughts on how to guarantee
 that the GUIS will be the same size on both machines (and evetually on a PC
 X Server, maybe Hummingbird) would be greatly appreciated.

 One other thing I've noticed regarding size differences is that under olwm 
 I'm unable to resize a window (by grabbing a corner) and have it scale up/down
 the contents of the window.  What I get is a larger or smaller window but
 everything in it (buttons, sliders, panes, etc...) is the original size.  Is
 this correct? This seems like a pretty basic requirement of all GUIS.  Is this 
 something that was omitted in olwm or will I have to provide that function in
 each of my application GUIs? Will devGUIDE generate the code for me?

 /*----------------*
  *    Problem #2  *
  *----------------*/

 Second problem.  I am building color GUIS with devGUIDE ( although the colors
 are only used for GUI elements (backgrounds, etc...) and I'm unable to get
 them to display with the correct colors under MacX.  I have been using Salmon
 and Turquoise as the colors.  I have managed to track down a few differences
 between SunOS/devGUIDE's color model (MIT X11?) and that of MacX.  It seems
 that all colors in MIT X11 are based on RGB value between 0-255.  On the Mac
 under MacX the RGB color range is between 0-65535.  The RGB value for Salmon 
 on the Sun side is 250 128 114.  The RGB value for Salmon on the MacX side 
 is 48640  26624  19968.  The actual color that displays on the MacX side is 
 Black instead of Salmon.  I tried using the Color Editor in MacX to enter the
 Sun's version of Salmon and I ended up with Black.  I guess this makes sense
 given the RGB values of 250 128 114 on a scale of 0-65535.  Nevertheless, I'm
 confused. I would think that the colors that are displayed would be looked up
 by NAME (Salmon and Turquoise) rather than by hard coded RGB values. 
 Am I wrong?  Am I headed in the right direction? Am I lost??

 I would really appreciate any help you might be able to give me.  A solution to
 the problems would be ideal. But if not, maybe some direction on who to talk to
 or what to try next.

 If you respond could you please send me a copy of your response via email.  I 
 have to log on to a different machine to read news and I often forget.  I really 
 would appreciate it.  

 If there are any other developers out there pursuing similar projects I'd love to
 discuss them with you.  I'll gladly respond to email or phone calls.

 Thank You Very Much,
