NAME¶
Tk::waitVariableX - a waitVariable with extensions.
SYNOPSIS¶
use Tk::waitVariableX;
$splash->waitVariableX( [$millis, $destroy_splashscreen], \$v1, \$v2} );
DESCRIPTION¶
This subroutine waits for a list of variables, with a timeout - the subroutine
returns when one of the variables changes value or the timeout expires,
whichever occurs first.
Although the millisecond parameter is required, it may be zero, which effects no
timeout. The milliscond paramter may also be an array of two elements, the
first the millisecond value, and the second a normal Per/Tk callback. The
callback is invoked just before waitVariableX returns.
Callback format is patterned after the Perl/Tk scheme: supply either a code
reference, or, supply an array reference and pass the callback code reference
in the first element of the array, followed by callback arguments.
