GUI in python

Collection of small programs to use with ros.

gui_sender.py

A simple interface that reads from an xml file with the format

<list>
    <button name='Start' event='e_start' tooltip='start the robot'/>
    <button name='Stop' event='e_stop'/>
</list>

Each button group produces a button that, if pressed sends the named event. The default topic is /events, but can be altered using the ros parameter 'topic_name', see gui_sender.launch for an example on how to change this. The tooltip is an optional field (text when hovering over a button). The xml file is stored in the rosparam "xml_button_file", that defauts to default.xml in the xml directory of this package.
