As with Motif(rg, LessTif consists of a widget set, a window manager,
and a UIL implementation (libMrm and the UIL compiler).
In LessTif, our main area of attention is the widget set.
We also have a working window manager mwm,
but UIL is not under very active development.
LessTif is licensed under the LGPL, the Library Gnu Public License.
The license itself accompanies LessTif in the file COPYING.LIB.
More information can be obtained from the Free Software Foundation.
DEBUGGING
For more info on Debugging check out our documentation in
HTML format.
ENVIRONMENT VARIABLES
DEBUG_SOURCES
Colon-separated list of files from which debug output
is generated. Special values "all"/"none" have obvious meaning.
To block entries from a list, add a "-" prefix.
You may use an asterisk "*" as a wildcard as well.
DEBUG_FILE
If this variable exists, then the file is being used for output.
If "%p" is part of the value of DEBUG_FILE, then it is replaced by the
current process id.
DEBUG_PRINT_WIDGETID
If this variable exists, then all widgets printed
with XdbDebug() etc. will also print their widget ID.
If the variable doesn't exist, then they only print
their name for identification.
DEBUG_REDIRECT_XMWARNING
If this variable exists any output of _XmWarning()
and equivalent functions is sent to the file specified by
DEBUG_FILE
DEBUG_SIGNAL
Specifies the name of the signal which should
be used to switch the built-in LessTif debugging system.
Valid values depend on the system on which LessTif was compiled
and is running and are a subset of:
SIGUNUSED, SIGUSR1, SIGUSR2, SIGUSR3, SIGBREAK
DEBUG_TOGGLE
Specifies the initial status of the built-in LessTif debugging system.
Valid values are 'on' and 'off'
INTERFACES
The following interfaces exist to Set, Toggle and Query the
current status of the debugging subsystem:
void
_LtDebugSet (Boolean flag);
void
_LtDebugToggle (void);
Boolean
_LtDebugQueryState (void);
SOURCE CODE
The major part of the source code which implements the
debugging system of LessTif resides in
/lib/Xm/DebugUtil.c Using the preprocessor define
LESSTIF_PRODUCTION the relevant code sections are en-/disabled during the build process.
