This procedure indirectly calls update
, a Tk utility
that processes pending events, including mouse events. If this
procedure is called from within an Itcl object, directly or
indirectly, it may be necessary to take precautions to prevent the
calling object from being deleted during the call. Because of a
defect in at least some versions of Itcl, failure to do so can result
in catastrophic failure of the application (a core dump). In Tycho
objects, the safeEval
method should be used to evaluate
this procedure or any method or procedure that in turn calls this
procedure. If the procedure is called from the top level or from a
Tcl procedure that is not itself called from within an Itcl object,
then there is no cause for worry.
