There is no error. rqt just closes.

Hi!

I want to make a compass plugin in rqt, but I'm finding it quite hard since it's not a widget for compass in qtCreator. Have anyone done this before or have any suggestions on how to do it/where to begin? I'm using python if that's relevant.

I've tried to implement this one from the link below, but I get errors on qwt that I can't figure out. https://github.com/SyllogismRXS/syllo...

I had to cast the data to String. There was also some bugs on the Subscriber, but with your tips on debugging I got it to work.

Thanks, that helped a lot. Got it to work now!

I'm writing a rqt plugin in python, but can't get the subscriber to work. I want the string from "controller/mode" to show in "lineControlMode". For some reason this doesn't happen. Hope some of you can help me.

import os
import rospkg
import rospy

from qt_gui.plugin import Plugin
from python_qt_binding import loadUi
from python_qt_binding.QtWidgets import QWidget, QGraphicsView
from std_msgs.msg import String

class MyPlugin(Plugin):

def __init__(self, context):
    #PLUGIN CODE
    super(MyPlugin, self).__init__(context)

    # Give QObjects reasonable names
    self.setObjectName('MyPlugin')
    rp = rospkg.RosPack()

    # Process standalone plugin command-line arguments
    from argparse import ArgumentParser
    parser = ArgumentParser()
    # Add argument(s) to the parser.
    parser.add_argument("-q", "--quiet", action="store_true",
                  dest="quiet",
                  help="Put plugin in silent mode")
    args, unknowns = parser.parse_known_args(context.argv())
    if not args.quiet:
        print 'arguments: ', args
        print 'unknowns: ', unknowns

    # Create QWidget
    self._widget = QWidget()
    ui_file = os.path.join(rp.get_path('rqt_vortex_control_mode'), 'resource', 'MyPlugin.ui')

    # Extend the widget with all attributes and children from UI file
    loadUi(ui_file, self._widget)

    # Give QObjects reasonable names
    self._widget.setObjectName('MyPluginUi')

    # Add widget to the user interface
    context.add_widget(self._widget)

    #MY CODE
    self._widget.lineControlMode.setReadOnly(True)
    self._widget.lineControlMode.setText("init")

    #Subscriber
    self.sub = rospy.Subscriber("/uranus_dp/controller/mode", String, self.callback)

def shutdown_plugin(self):
    self.sub.unregister()

def callback(self, mode):
    self._widget.lineControlMode.setText(mode)

Here is the link to my repository just in case: https://github.com/vortexntnu/rov-gui

Did you figure out how to integrate it?

I'm trying to make my own rqt plugin. I've been through the tutorials and been following this link so far: http://answers.ros.org/question/24939...

I've met a lot of problems, and most of them has to do with what files to use. I use Qt Creator to create the .ui file. My confusion is what other files do I need since there is a lot of files being produced by Qt. So far I've moved the .ui file into src.

Could someone make a overview or something to help my confusion?

Thanks, that worked!

I've been trying to make my own rqt plugin. After a lot of back and forth, I finally got it to build. The problem now is that rqt won't run. I get the message listed below. In the last line, rqt_mypkg is listed as KeyError. This is a package I had once before, but is deleted from my workspace now. I've tried cleaning and deleting my workspace, removing and reinstalling rqt, removing and reinstalling ros but nothing works. Rqt still won't run. Anyone have any idea what is wrong?

Thanks, that worked! I've gotten catkin to build now, but when I try to start rqt I get: RosPluginProvider._parse_plugin_xml() could not parse. Got any ideas as what the problem is? I've updated my repo

I fixed the last error, but have a new one: catkin_ws/src/rqt_mypkg_test/include/rqt_cpp_test/my_plugin.h:25:7: error: ‘MyPluginWidget’ in namespace ‘Ui’ does not name a type

Sorry for the late reply. Here is my repo: https://github.com/fonstein/rqt_test

Also, the example you included in A; I can get the python plugin to work, but not the one for C++. The plugin shows, but it won't show

The only thing is that it can find the other .h file that is included in the exact same way and located in the same folder. Any ideas why?

Hi! I've been following your guidance above. Thank you so much for a lot of help. However, I'm stuck. At this point I get an error similar as above regarding the .h file; catkin_ws/src/rqt_mypkg_test/include/rqt_cpp_test/ui_mainwindow.h:13:29: fatal error: QtWidgets/QAction: No such file or directo
