Hello everyone

I want to know how I can close my rqt plugin when I push a button on it.

I tried with exit(0) but it close the plugin like if it was an error in a thread (My plugin doesn't use threads) and the last thing I tried was widget.close() but this one close the widget but rqt main window continues running.

I will appreciate any help.Thanks

You might want to try calling the method shutdown_plugin on the plugin instance.

Hello Dirk Thomas I connect the button with shutdown_plugin() but it doesn't work. Freeze the plugin and seconds later the terminal show the following [FATAL] [1487975743.765361534]: ASSERTION FAILED file = /opt/ros/indigo/include/ros/publisher.h line = 102 cond = false message = [FATAL] [..]..

Since the error message is truncated I can't say much but it looks a lot like that your plugin is actually trying to close but does something wrong during that. Maybe it doesn't close all handles correctly?

Hello Dirk Thomas, I remove the subscribers in the shutdown function and it works. Thank you for your help
