2019-06-05 10:10:51 -0500 | marked best answer | Custom QT GUI in ROS for real time data freeze Hi, I am new to integrating ROS with QT. I am developing a custom gui to publish topic directly to a GUI that displays data in real time as it is read from a unit.
I followed this link: http://wiki.ros.org/qt_create/Tutoria... . main_winndow.cpp qnode.cpp I have read couple of posts that say to use QTime. Could someone help me how I can use Qtime in my example. If Qtime is not the right way to defreeze then what is the right method to go about to display real time topic without GUI freeze. |

Master runs successfully New terminal I type in "roslaunch /home/userid/catkin_ws/src/robot/launch/robot.launch". This basically open RVIZ with the robot model in grid successfully Above steps are implemented as follows in bash and python script and it does NOT work. ##bashscript.sh ##pythonscript.py This fails. RVIZ opens with a white blob in center on grid NOT the robot model. and left hand panel it says robot model error. status error. Why rviz wouldn't work with script? |
