Hi!
I was wondering how difficult it would be to port a Motif-based
application to gtk. Has anyone experiences with this?

I ported MXaudio (http://www.xaudio.com/mxaudio) to GTK in a week or so,
including special widget coding. The result is gxaudio
(http://www.cybersoft.org/gxaudio), and I like it better than the old
Motif version. (I must say I did it in my free time, no for any work
related reason).
Basically, if you take your C Motif code, since GTK has about the same
concepts, you still have all your callbacks working about the same way,
so no surprise at all. Any other fancy stuff (timers, listening on a
pipe, ...) works the same.
I would say also than all the dialog problems you experience with Motif
(you never know when to Popup, Realize, ...) is gone with GTK: you just
show...
And then, compiling GTK on any platform is easy, so even on my Solaris
box, I prefer to use GTK than Motif, even if Motif is bundled with the
OS...
So go for it, do your port !!! :)

Depends on the application. I've been porting a Motif version of my
XPostitPlus (now named XNotesPlus) to Gtk recently. For the most part its
been pretty straight forward. The biggest difference is the use of
resources. In Motif you have app-defaults files. In Gtk you have to use
.rc files, and these aren't quite as easy to use (IMHO, of course). I also
had to write a command line parser along the lines of getopt_long() so that
I could use the same command line args in either version and still
guarantee portability (since getopt_long() isn't on all Unix platforms by
default).
Some differences I can remeber off hand: there isn't a standard method for
setting background colors for all widgets. Some use "bg", others use
"base". The label widget, for example, doesn't appear to be able to have
its background set to a different color from the .rc file (although you can
probably do it programmatically using GC's). There also seem to be 5
element arrays for bg, fg, and other colors. I thought this might be the 3
RGB colors plus 1 alpha channel, but I don't know what the 5 element is for.
Most of the differences are mostly just a matter of learning the new API.
In general its easier (re: less code) to create a window component (label,
text field, etc) in Gtk, but its harder to do all the things that are
handled in convenience routines in Motif. The latter is probably just a
matter of time for Gtk - its still a young widget set. The use of common
resources, like background colors, are not consistant across all widgets
yet. One annoying factor is that the dialogs in GTK have the same resource
name as the main window. My XNotesPlus main window is set to have no
borders by the window manager (fvwm). With Motif the individual notes have a
different resource name (they are PopUp's) so they have borders and title
bars. With GTK all the notes have no title bars (no matter if I make them
dialogs or popups). I'm not sure how to get around this one yet.
And, of course, theres not printed manuals for Gtk. (Yet.) :-)
I'm still fairly new to Gtk myself and this is just based on my experiences
so far. I have a moderately long list of things I've noted about dealing with
Gtk that Motif programmers might find useful. If you're interested I'll
pass it along. Eventually, I'll either post it on my web site or just
point folks to my XNotesPlus package (which will include it too).

I think that these 5 element arrays are for the 5 different states,
NORMAL, ACTIVE, PRELIGHT, SELECTED, and INSENSITIVE (see the first entry
in gtkenums.h.) Each of the states has a set of GCs to describe what the
widget is supposed to look like in that state.
This is how the buttons turn bright when you enter them with the mouse and
dark when they're depressed. This is also how testgtk changes the colors
for the PRELIGHT state.

- bg[] and base[] are used for different things. I'm note sure how
to describe the difference other than saying that bg[] is the
background for things that are by default gray, and base[] is
the background for things that are normally white. Note that
some widgets (Like the Text and Entry widgets) have both types
of backgrounds within them, so they couldn't be controlled by
the same setting.
- Labels actually don't have an independent background at all -
they are text without background. To control their background,
set the background color for their parent. (An EventBox is
suitable if you don't want anything else).

You can set this with:
void gtk_window_set_wmclass (GtkWindow *window,
const gchar *wmclass_name,
const gchar *wmclass_class);
