It intercepts all mouse events, and then selectively sends commands on to AVS for action. This version ignores all normal image viewer mouse controls, and causes special behavior instead. The left button will "zoom in" the image, while the right button will "zoom out" again, each by a preset amount. It is intended as an AVS application developers example, to create custom interface controls. This module also shows how to change the mouse cursor shape while over viewer window. This is intended as a source example for further development work. The implementation is to make an invisible input only window, exactly covering the geometry viewer window. Events from this invisible window are detected, masking the geometry viewer window native events. Commands are then sent via the CLI mechanism. As a coroutine, this module can also take events from user interface parameters, or send event information to output ports, although none are present in this version. </pre> </blockquote> <h3>Related modules</h3> <blockquote> <pre> mouse_trap </pre> </blockquote> </body> </html>  </td> </tr> </table> </td> </tr> <tr height="100%"> <td class="sideLink" width="25%" align="left" valign="top" nowrap="nowrap"> <p><a href="../../../../../general/index.shtml" target="_top">General Information</a></p> <p><a href="../../../../../repository/index.shtml" target="_top">Repositories</a></p> <p class="sideLinkLevel2"><a href="../../../../new/index.shtml" target="_top">  New Releases</a></p> <p class="sideLinkLevel2"><a href="../../../../download/index.shtml" target="_top">  Download</a></p> <p class="sideLinkLevel2"><a href="../../../../submit/index.shtml" target="_top">  Submit</a></p> <p class="sideLinkLevel2"><a href="../../../../pfiles/index.shtml" target="_top">  Project Files</a></p> <p class="sideLinkLevel2"><a href="../../../../avs5/index.shtml" target="_top">  AVS5</a></p> <p class="sideLinkLevel3"><a href="../../../input.shtml" target="_top">    Data Input</a></p> <p class="sideLinkLevel3"><a href="../../../filters.shtml" target="_top">    Filters</a></p> <p class="sideLinkLevel3"><a href="../../../mappers.shtml" target="_top">    Mappers</a></p> <p class="sideLinkLevel3"><a href="../../../output.shtml" target="_top">    Data Output</a></p> <p class="sideLinkLevel3"><a href="../../../misc.shtml" target="_top">    Miscellaneous</a></p> <p class="sideLinkLevel2"><a href="../../../../express/index.shtml" target="_top">  AVS/Express</a></p> <p class="sideLinkLevel2"><a href="../../../../pog/index.shtml" target="_top">  Project Guidelines</a></p> <p><a href="../../../../../usergroup/index.shtml" target="_top">User Group</a></p> <p><a href="../../../../../training/index.shtml" target="_top">Training Materials</a></p> </td> </tr> </table> <table width="100%" border="0" cellspacing="0" cellpadding="0" bgcolor="c6c6e0"> <tr> <td><img src="../../../../../img/foot1.gif" alt="IAC" width="155" height="25"></td> <td width="100%"> Last Updated:  26th November 2002 </td> </tr> </table>
