You sure can. There really are two ways. You can use it directly, or through one of the C++ wrappers for Motif. Much of this is discussed in the Motif FAQ which can be found at Ken Lee's website at http://www.rahul.net/~kenton Using LessTif directly with C++ prompts the question on how to use class member functions as callbacks.

You should be able to compile and run your code, how well it works is another matter... If it doesn't, then we're very interested in hearing about what doesn't work and why (we can't fix bugs that we don't know about), and we're even more interested in a fix. If your favorite application does work, please tell us so we add it to the list of apps known to work.

A few Internet based individuals as listed in core.html. Nobody is paid to work on it, all is effort by volunteers. Look for an all-time list of authors in the AUTHORS file in the LessTif distribution, while CREDITS acknowledges the contributions of various other people. Keeping a list of developers for each widget is not really possible mainly because the we're not fanatic about ownership of a widget. We do keep in touch enough to know who's messing with what so we don't overlap too much.

Regularly, questions about LessTif (or about any free Motif®) clone are asked in comp.windows.x or comp.windows.x.motif .

A more accurate list is available in an extraneous file. Here's an excerpt, with version numbers stripped for brevity: Linux, FreeBSD, NetBSD, OpenBSD, BSDi (BSD/OS), Sun (SunOS, Solaris), MkLinux, OS/2, AIX, Digital UNIX/Compaq Tru64, HP/UX, Windows NT, Windows 95 (with cygwin)

Actually most LessTif widgets work somewhat. Many work fairly well. Things like traversal and focus handling have been worked on, but probably aren't really all that functional yet. The menu system is quickly losing its child diseases (occasionally freezing the X server with grabs). If you're not in a rush when working the menus, the odds are low that you'll get in much trouble. Also dragging in the menus will get you in trouble faster than clicking.

C++ is a superset of something, we're not sure what. You can use a C++ compiler to compile C code, but the results may surprise you.

Up to now we are very close, all interfaces are in place, we might only have to fight against some remaining bugs ... Therefore, we expanded the source directory tree to make it easy to add new stuff, and to build several versions of the library (and the corresponding tools). So if anybody has a widget, or an application, to offer which can advance us in the 2.x or CDE areas, please E-mail us. Somewhere along 1997 we actually started building 2.0 compliant widgets.

We have some documents which should help to track down bugs in LessTif-based applications. BUG-HUNTING.html describes some specifics of LessTif's built-in debugging facilities while bugs.html covers more general the topic of debugging X11 applications.

You may have an application that's not error-free; or (more likely) one which needs configuration for your site, computer platform, etc. If it's not a bug within the application it probably has to do with your compiler options. If it's indeed that, there are several possibilities. In the examples we'll give now, we'll be using some installation directories that may differ from your installation.

No, C# has no direct equivalent of the C++ typedef. C# does allow an alias to be specified via the using keyword: using IntList = System.Collections.Generic.List<int>; but the alias only applies in the file in which it is declared. A workaround in some cases is to use inheritance: public class IntList : List<int> { }

Yes, in fact exceptions are the recommended error-handling mechanism in C# (and in .NET in general). Most of the .NET framework classes use exceptions to signal errors.

No, you should not use a rechargeable battery with your Seiko Cleancut and here's why. The speed of any DC motor is directly related to the voltage of the power supply; the higher the voltage the faster the motor turns. By their nature rechargeable batteries do not have as high a voltage as alkaline batteries. For instance a fresh alkaline "C" cell, which is a 1.5 volt battery, will test out as high as 1.6 volts right out of the package.
