time with widgets. I was wondering how the new proposals may help.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>1. Handle geometry – can the 3D handles be made
to remain a fixed size, independent of any camera zooming? It would also be
nice if they could snap to points.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>2. Widget conflicts – I use several scalar bar
actors/widgets and suffer from them being placed on top of each other because I’m
too lazy to check the position! Typically, you just want these widgets not to
obscure your view or each other. Maybe there is a case for a class of widget that
just ‘transports’ certain actors/info around the render window.
Some simple spatial management functions could then be defined.</span></font></p>

custom widgets using existing widgets a</span></font><font size=2 face=Arial><span

For example, suppose I want a ruler widget consisting of 2 cone handles, a line
connecting the handles and a text box to continuously display the distance
between the cones. All the individual components are built but can they easily
be combined?</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>4. Single use widget – widgets for making some
form of 1-off selection might typically enable on mouse button down, select on
mouse move and disable on mouse button up. Presumably the customised event
binding will allow this type of configuration.</span></font></p>
