Tk::tkvars - Variables used or set by Tk
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.)
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).
Note: this is Tcl remnant. With perl it makes more sense to use $Tk::VERSION described below.
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.
Note: this is Tcl remnant. With perl it makes more sense to use $Tk::VERSION described above.
