tkvars - Variables used or set by Tk
The following Tcl variables are either set or used by Tk at various times in its execu-
tk_library This variable holds the file name for a directory containing a library of
Tcl scripts related to Tk. These scripts include an initialization file
that is normally processed whenever a Tk application starts up, plus other
files containing procedures that implement default behaviors for widgets.
The initial value of tcl_library is set when Tk is added to an interpreter;
this is done by searching several different directories until one is found
that contains an appropriate Tk startup script. If the TK_LIBRARY environ-
ment variable exists, then the directory it names is checked first. If
TK_LIBRARY isn't set or doesn't refer to an appropriate directory, then Tk
checks several other directories based on a compiled-in default location,
the location of the Tcl library directory, the location of the binary con-
taining the application, and the current working directory. The variable
can be modified by an application to switch to a different library.
tk_patchLevel Contains a decimal integer giving the current patch level for Tk. The
patch level is incremented for each new release or patch, and it uniquely
identifies an official version of Tk.
tkPriv This variable is an array containing several pieces of information that are
private to Tk. The elements of tkPriv are used by Tk library procedures
and default bindings. They should not be accessed by any code outside Tk.
tk_strictMotif This variable is set to zero by default. If an application sets it to one,
then Tk attempts to adhere as closely as possible to Motif look-and-feel
standards. For example, active elements such as buttons and scrollbar
sliders will not change color when the pointer passes over them.
tk_version Tk sets this variable in the interpreter for each application. The vari-
able holds the current version number of the Tk library in the form
major.minor. Major and minor are integers. The major version number
increases in any Tk release that includes changes that are not backward
compatible (i.e. whenever existing Tk applications and scripts may have to
change to work with the new release). The minor version number increases
with each new release of Tk, except that it resets to zero whenever the
major version number changes.
