No publisher plugin available for RQT #101

Closed chrisspen closed 9 years ago

chrisspen commented 9 years ago

Under the "Use RQT To Send Commands" section of the ROS control tutorial it says:

Add the 'Publisher' plugin then choose the topic from the drop down box that commands any particular controller that you want to publish to.

However, RQT no longer displays any such menu item. I've installed all the ros-indigo-rqt-* packages on Ubuntu 14.04, and this is a screenshot of the resulting RQT plugins menu. There's no "Topics->Publisher" item available.

I originally reported this as a bug to the gazebo_ros_demos maintainer, but he claims this is a problem with RQT.

dirk-thomas commented 9 years ago

The plugin is called "Message Publisher" in the groups "Topics" in the "Plugins" menu. It should be available when you install ros-indigo-rqt-publisher. I would assume that this is not a bug in rqt itself but a problem with your specific installation because it works well for others.

Can you please post more information about your installation, e.g. the output of the following command:

dpkg -l | grep ros-indigo-rqt

I have ros-indigo-rqt-publisher installed as well as every other ros-indigo-rqt-* package.

ii  ros-indigo-rqt                                              0.2.14-1trusty-20150327-0415-+0000                     amd64        rqt is a Qt-based framework for GUI development for ROS. It consists of three parts/metapackages rqt (you're here) rqt_common_plugins - ROS backend tools suite that can be used on/off of robot runtime. rqt_robot_plugins - Tools for interacting with robots during their runtime. rqt metapackage provides a widget rqt_gui that enables multiple `rqt` widgets to be docked in a single window.
ii  ros-indigo-rqt-action                                       0.3.10-0trusty-20150329-1114-+0000                     amd64        rqt_action provides a feature to introspect all available ROS action (from actionlib) types. By utilizing rqt_msg, the output format is unified with it and rqt_srv. Note that the actions shown on this plugin is the ones that are stored on your machine, not on the ROS core your rqt instance connects to.
ii  ros-indigo-rqt-bag                                          0.3.10-0trusty-20150326-1826-+0000                     amd64        rqt_bag provides a GUI plugin for displaying and replaying ROS bag files.

To run any rqt plugins, just type in a single command "rqt", then select any plugins you want from the GUI that launches afterwards. rqt consists of three following metapackages: rqt - core modules of rqt (ROS GUI) framework. rqt plugin developers barely needs to pay attention to this metapackage. rqt_common_plugins (you're here!) rqt_robot_plugins - rqt plugins that are particularly used with robots during their runtime.
ii  ros-indigo-rqt-console                                      0.3.10-0trusty-20150327-0621-+0000                     amd64        rqt_console provides a GUI plugin for displaying and filtering ROS messages.

Its components are made generic so that other packages where you want to achieve graph representation can depend upon this pkg (use rqt_dep to find out the pkgs that depend. rqt_dep itself depends on rqt_graph too).

Despite no plugin is provided, this package is part of the rqt_common_plugins repository to keep refactoring generic functionality from these common plugins into this package as easy as possible. Functionality included in this package should cover generic ROS concepts and should not introduce any special dependencies beside "ros_base".
ii  ros-indigo-rqt-py-console                                   0.3.10-0trusty-20150326-1743-+0000                     amd64        rqt_py_console is a Python GUI plugin providing an interactive Python console.

(12/27/2012) In the future, arbitrary parameters that are not associated with any nodes (which are not handled by dynamic_reconfigure) might become handled. However, currently as the name indicates, this pkg solely is dependent on dynamic_reconfigure that allows access to only those params latched to nodes.
ii  ros-indigo-rqt-robot-dashboard                              0.4.0-0trusty-20150328-2209-+0000                      amd64        rqt_robot_dashboard provides an infrastructure for building robot dashboard plugins in rqt.

All diagnostics are fall into one of three tree panes depending on the status of diagnostics (normal, warning, error/stale). Status are shown in trees to represent their hierarchy. Worse status dominates the higher level status. Ex. 'Computer' category has 3 sub devices. 2 are green but 1 is error. Then 'Computer' becomes error. You can look at the detail of each status by double-clicking the tree nodes. Currently re-usable API to other pkgs are not explicitly provided.

To run any rqt plugins, just type in a single command "rqt", then select any plugins you want from the GUI that launches afterwards. rqt consists of three following metapackages: rqt - provides a container window where all rqt tools can be docked at. rqt plugin developers barely needs to pay attention. rqt_common_plugins - ROS backend tools suite that can be used on/off of robot runtime. rqt_robot_plugins (You're here!)

@chrisspen try:

chrisspen commented 9 years ago

This is odd. I just re-ran:

sudo apt-get install ros-indigo-desktop-full

and it ran perfectly, but when I run the upgrade I get the error:

The following packages have unmet dependencies:
  ros-indigo-ipa-canopen : Depends: ros-indigo-ipa-canopen-core but it is not installable
                      Depends: ros-indigo-ipa-canopen-ros but it is not installable

It seems neither of those packages exist in the repo...

dirk-thomas commented 9 years ago

What does the following command output:

rqt --list-plugins

Please also try running and post the output:

rospack profile
chrisspen commented 9 years ago

Ah, thanks. It looks like my reinstall of desktop-full fixed the RQT plugin issue, because I'm now seeing the Topic item. This issue with upgrading and ros-indigo-ipa-canopen seems unrelated, so I'll report that elsewhere.

davetcoleman commented 9 years ago

Glad we got to the bottom of this!

Chrispako990210 commented 1 week ago

On a side note, I had the same problem with ros humble. Ive done sudo apt install ros-humble-rqt-* and reinstalled the desktop-full. When I use the dpkg -l I see the packages downloaded but with rqt --list-plugins they dont show up. What worked for me was to launch rqt --force-discovery. Does anybody know how to work around this?
