How to connect a Qt-GUI to ROS
Hi,
I'm currently working on a C++ Qt-GUI with which I intend to remote control a ros-controlled robot. Now I'm fairly new to both ROS and Qt and I'm not quite sure how to combine both.
The robot is equipped with some cameras. What do I have to do to show the video data in the GUI? Does the GUI need to be a ROS-node as well to subscribe to the camera-topic (sensor_msgs/Image in this case)? Some people were apperently working with a QThread as ROS-node.
There seems to be a ROS Qt Creator Plug-in. Would you suggest to use that? I didn't quite manage to set it up yet.
Thanks a lot for your help!
