[incr\ Tk]
NAME
itkvars - variables used by [incrTk]
DESCRIPTION
The following global variables are created and managed
automatically by the [incrTk] library. Except where noted
below, these variables should normally be treated as read-only by
application-specific code and by users.
- itk::library
- When an interpreter is created, [incrTk] initializes
this variable to hold the name of a directory containing the system
library of [incrTk] scripts. The initial value of
itk::library is set from the ITK_LIBRARY environment
variable if it exists, or from a compiled-in value otherwise.
When [incrTk] is added to an interpreter, it executes the
script "init.itk" in this directory. This script, in turn, looks
for other script files with the name "init.xxx". Mega-widget
libraries will be automatically initialized if they install a
script named "init.xxx" in this directory, where
"xxx" is the name of the mega-widget library. For example,
the [incrWidgets] library installs the script
"init.iwidgets" in this directory. This script establishes the
"iwidgets" namespace, and sets up autoloading for all
[incrWidgets] commands.
