.SH DESCRIPTION
|
|
.PP
|
|
The following STk variables are either set or used by Tk at various times
|
|
in its execution:
|
|
.TP
|
|
\fB*tk-patch-level*\fR
|
|
Contains a string which represent 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.
|
|
.TP
|
|
\fB*tk-strict-motif*\fR
|
|
This variable is set to \fB#f\fR by default.
|
|
If an application sets it to a true value, 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.
|
|
.TP 15
|
|
\fB*tk-version*\fR
|
|
Tk sets this variable in the interpreter for each
|
|
application. The value of this variable is a string which holds the
|
|
current version number of the Tk library in the form
|
|
\fImajor\fR.\fIminor\fR. \fIMajor\fR and \fIminor\fR 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.
