Re: [ros-users] rviz is moving to Qt, preview available

Hi Dave,

these are great news!
I tested it today and it seems to work fine.
So I went on and made a first simple integration as a rosgui plugin.
The plugin just loads the rviz_qt lib, instantiates the
VisualizationFrame and puts it into a dockwidget for rosgui.
The code is in the rosgui git and a screenshot of it running next to
some other plugins can be seen here:

I came across one problem though. When I closed the plugin and reopened
it, an assertion is failing:
> python:
> /tmp/buildd/ros-electric-visualization-common-1.6.2/debian/ros-electric-visualization-common/opt/ros/electric/stacks/visualization_common/ogre/build/ogre_src_v1-7-3/OgreMain/include/OgreSingleton.h:80:
> Ogre::Singleton<T>::Singleton() [with T = Ogre::LogManager]: Assertion
> `!ms_Singleton' failed.
> Aborted
I have not yet investigated this any further. I'll file a bug report
when I know more...

Cheers,
Dorian
