rqt_ez_publisher's Issues

Removing an element of a MultiArray doesn't actually remove it from being published

(I found this to be unexpected behavior when testing your fix for #17 , but this could just be a Garbage In -> Garbage Out problem. Feel free to close as wontfix.)

When publishing a MultiArray topic, removing an element in the GUI doesn't actually remove it from being published on the topic.

For example,

• Publish a MultiArrayFoo with one element -> len(data) = 1
• Add an additional element -> len(data) = 2
• Remove element data[1] -> len(data) = 2 still (I would have expected 1), and the last stored value gets published in data[1].

On a related note, removing an element that is not the last (e.g., data[1] with 3 elements) also keeps publishing the last stored value in data[1]. Perhaps setting the value to zero could be more intuitive.

Is it possible to rename the window title?

When starting rqt_ez_publisher directly (i.e., rosrun rqt_ez_publisher rqt_ez_publisher) the window title is always rqt_ez_publisher__EzPublisher - rqt.

Is there a way to change this? I started exploring your code (you set the widget title when running it inside rqt), but got pretty far into the qt_gui code before getting super lost.

Running on hydro

rosrun rqt_ez_publisher rqt_ez_publisher

Following exception:

And GUI displays only list of topics:
topic(+data member) name ..... all clear
Nothing

Fails on nested topics

Thanks for the great tool.

I found an issue when attempting to publish to a nested topic, for example the following Subscribers:

rospy.Subscriber('/some/topic', Float32)
rospy.Subscriber('/some/topic/again', Float32)
rospy.Subscriber('/this/works', Float32)

Selecting /some/topic works, but /some/topic/again produces the following (very frequent) error message:

[WARN] [WallTime: 1459858994.495491] 'again' is not in list
[WARN] [WallTime: 1459858994.513921] 'again' is not in list
[WARN] [WallTime: 1459858994.530778] 'again' is not in list
[WARN] [WallTime: 1459858994.547622] 'again' is not in list

uint8 type treated as string

I am writing to a topic that has an array of type uint8 in it. When I adjust the slider, I get the following error message. It appears that python is handling the uint8 array as an array of strings. When I change the datatype of the array to uint32, I no longer get this error.
Here is the traceback:

quaternion -> rpy

quaternion is very difficult to change by slider.
convert it to rpy gui.

save/load settings by text

It is useful if the setting is shared

publishing rate

Nice tool! it will be great to decide the publishing rate of the messages.

save repeat

save checkbox state

range: max value 10000

I'm using rqt_ez_publisher to publish some float32 topic, unfortunately max range is -10000 10000.

Pls update to be a float32 maxrange.

replace sliders

save min/max value

save value of spin box and restore it.

array of non builtin type

this version support builtin only

rqt_ez_publisher not found in melodic distro

Slider Step

I'd like to set the sliders step if it isn't already possible.

v0.3.1 problem

I am trying to publish a topic of type joint_trajectory http://docs.ros.org/jade/api/trajectory_msgs/html/msg/JointTrajectory.html and a node is correctly subscribing to the topic. This worked perfectly with v0.3.0 but since v0.3.1 the tool fails to show the topic attributes with the following error:

[WARN] [WallTime: 1462037896.472686] 'positions' is not in list
File "/opt/ros/indigo/lib/python2.7/dist-packages/rqt_ez_publisher/ez_publisher_widget.py", line 102, in add_slider_by_text self.add_slider_by_text(string)

I tried v0.3.0 and it worked well, so I think it is an issue with the new version.

Thanks!

remove seq of header

seq is overwritten by system, so even if there are seq GUI, it is useless.
Please do not create the GUI.

button size

more small button is suitable for close

auto repeat

ros sometimes requires auto repeated topic.

zero button

reset value to zero.

support array input

input size of array first, and build multiple sliders.

Update document

Add description for setting file.

• save and load
• command line

rqt_ez_publisher for ros-noetic

Could you please add this package to the noetic distribution of ROS? Thank you so much!

Does not work for custom actions defined in own catkin workspace

Hi,

I have specified an action in my own workspace here:
/home/koenlek/hydro_catkin/src/semantic_turtle_meta/st_navigation/action/GotoNode.action

This automatically generates to related messages here:
/home/koenlek/hydro_catkin/devel/share/st_navigation/msg/GotoNodeAction[subaction_type].msg

However, your plugin throws an error when I want to publish to e.g. /move_base_topo/goal the error is:
IOError: [Errno 2] No such file or directory: u'/home/koenlek/hydro_catkin/src/semantic_turtle_meta/st_navigation/msg/GotoNodeActionGoal.msg'

Clearly, it is looking in the wrong directory. Maybe make sure to also look into the devel folder (I would suggest to first try src, then devel, then install, and only continue looking if the current failed)?

automatic header/stamp

if there are header/stamp, set current time.
this enable static transform publisher

How to install?

Hello I am wondering how to install this plugin. The install section of the README has been left blank, and I can't find information online about installing rqt plugins.

Running catkin_make in the directory root does not seem to work.

Creating a build directory, running cmake .. then make also does nothing (cmake generates the configuration files but make does nothing, and I receive a 'no package error' when I try to run).

Am I missing something or just being incredibly stupid?

Thanks
