perl Tkx - DynamicHelp

[Mike Ignatoski]

Perl/Tcl/Tk/Tkx Users,

I'm using Perl Tkx, so this is sort of a Tcl/Tk question, also.

I'm trying to delete some balloon help text from a Tk Canvas item using
the BWidget widget, DynamicHelp.

This code adds the help (works fine)

Tkx::DynamicHelp__add ( $canvasTop, -item=> 'ab_atk',
-text => 'My tooltip help text' );


This code does NOT work, results in run-time error.

Tkx::DynamicHelp__delete ( $canvasTop, -item=> 'ab_atk' );


This code seems to act as a good workaround
Tkx::DynamicHelp__add ( $canvasTop, -item=> 'ab_atk',
-text => '' );

Although the work around seems to work fine, I was wondering if there
was a way to use the "delete" method.


Thanks,
Mike

This seems to be an API flaw in DynamicHelp. The above shouldn't take args, but only supports removing all help on said widget.

This seems to be the proper functional method when using -item indexing.
