NAME

       tkvars - Variables used or set by Tk

DESCRIPTION

       The following perl variables are either set or used by Tk at various times in its execution. (For a list of variables used by perl see
       perlvar.)

       $Tk::library
	   This variable holds the file name for a directory containing the modules related to Tk.  These modules 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 $Tk::library is set when Tk is added to an interpreter;  this is done by searching searching for a
	   directory named Tk in the directory where the file Tk.pm, or the first directory Tk in @INC.

	   The TK_LIBRARY environment variable used by Tcl/Tk is not supported by perl/Tk.  Please use @INC to change where modules are searched.

	   Note: This is Tcl remnant. With perl it makes more sense to use @INC and %INC).

       $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.

	   Note: this is Tcl remnant. With perl it makes more sense to use $Tk::VERSION described below.

       $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
	   The variable holds the current version number of the perl/Tk release in the form major.minor.  Major and minor are integers.

	   The major version number shows on which Tcl/Tk release perl/Tk is based.  E.g., 402 means based on Tcls Tk 4.2.  (Patchlevel of Tcls Tk
	   are not incorporated because perl/Tk tended	to be ``ahead'' of them on some fixes and behind on others.  The first digest of the major
	   version number increases in any Tk release that includes changes that are not backward compatible (i.e. whenever existing perl/Tk
	   applications and scripts may have to change to work with the new release).

	   The minor version depends on perl/Tk only. It uses the 'even'='stable', 'odd'='experimental' scheme that linux uses:

	    .0xx  - inherently 'alpha'
	    .1xx  - experimental 'beta'
	    .2xx  - stable
	    .3xx  - experimental
	    .4xx  - stable
	    ...

	   The minor version number increases with each new release of Tk, except that it resets to zero whenever the major version number
	   changes.

       $Tk::version
	   The variable 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.

	   Note: this is Tcl remnant.  With perl it makes more sense to use $Tk::VERSION described above.
