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

Hi guys,

Thank you very much for all the reply! They are very helpful!

I have taken some time to merge the matplotlib into ros-gui for real-time

I'd like to merge all my code in ros_gui stack. But what shall I do?

But before going further, I have some question:

This is very useful! But what if both two ros_gui plugins have a same
widget? Apparently loading a same widget twice is not efficient. At the
moment I don't think there is a communication scheme between plugins in
ros_gui. Am I right?

 And I'll soon implement rxbag in ros-gui.

Ecto is new to me, I will take look at it. Actually I'm very interesting in
the rosh. The ipython integration can help me to analyze the real-time data
by Python scripting. Maybe a rosh plugin for ros_gui is valuable?

Cheers,
