.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
The following Tcl variables are either set or used by Tk at various times
|
||
|
|
in its execution:
|
||
|
|
.TP 15
|
||
|
|
\fBtk_library\fR
|
||
|
|
Tk sets this variable hold the name of 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.
|
||
|
|
.VS
|
||
|
|
The value of this variable is taken from the TK_LIBRARY environment
|
||
|
|
variable, if one exists, or else from a default value compiled into
|
||
|
|
Tk.
|
||
|
|
.VE
|
||
|
|
.TP
|
||
|
|
\fBtk_patchLevel\fR
|
||
|
|
.VS
|
||
|
|
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.
|
||
|
|
.VE
|
||
|
|
.TP
|
||
|
|
\fBtk_priv\fR
|
||
|
|
This variable is an array containing several pieces of information
|
||
|
|
that are private to Tk. The elements of \fBtk_priv\fR are used by
|
||
|
|
Tk library procedures and default bindings.
|
||
|
|
They should not be accessed by any code outside Tk.
|
||
|
|
.TP
|
||
|
|
\fBtk_strictMotif\fR
|
||
|
|
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.
|
||
|
|
.TP 15
|
||
|
|
\fBtk_version\fR
|
||
|
|
Tk sets this variable in the interpreter for each application.
|
||
|
|
The variable 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.
|
||
|
|
.TP 15
|
||
|
|
\fBtkVersion\fR
|
||
|
|
Has the same value as \fBtk_version\fR. This variable is obsolete and
|
||
|
|
will be deleted soon.
