           Summary: Allow disabling key-based canvas interactors (or
                    disable them together with mouse-based interactors)
           Product: Batik
           Version: 1.8
          Platform: All
               URL: http://mail-archives.apache.org/mod_mbox/xmlgraphics-b
                    atik-users/201008.mbox/browser#msg-21
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P4
         Component: SVG Viewer
        AssignedTo: batik-dev@xmlgraphics.apache.org
        ReportedBy: helder.magalhaes@gmail.com


The JSVGCanvas class [1] supports several canvas interactors [2], key-based and
mouse-based (both often using key modifiers). The mouse-based can be disabled,
using the setEnable*Interactor() [1][2]; the key-based ones currently cannot be
disabled without extending the class.

There's a good description of the problem [3] and a proposed workaround [4]
(through extending the class).

The idea would be either:
1. Implement more setEnable*Interactor() methods to allow disabling key-based
interactors: cursor keys, zoom in/out as well and maybe the reset transform as
well;
2. Adjust the setEnable*Interactor() methods to disable the key-based
interaction as well. So, for example, "setEnablePanInteractor" method would
disable the cursor key interaction as well (including the shift key modifier).

This can be seen either as an enhancement or a minor bug report (in the sense
that currently there's already functionality for disabling mouse-based canvas
interactors).
