python_example

Overview

This is a sample application written in python which uses Qt (PySide) to display an empty widget on the wall. This example assumes you have gone through the WallFrame Tutorials and Overview and also understand what is going on with ROS and PySide

The Code

#!/usr/bin/env python
import roslib; roslib.load_manifest('modulair_app_python_example')
import rospy, sys
# Modulair Core Functionality
import modulair_core
from modulair_core import ModulairAppWidget
# PySide Imports
import PySide
from PySide.QtGui import QApplication

class PythonAppWidget(ModulairAppWidget):
  def __init__(self,name,app):
    super(PythonAppWidget,self).__init__(name,app)
    # Any child widgets should be put here and made with 'self' as a parent
    pass

class PythonExampleApp():
  def __init__(self):
    rospy.init_node('python_example_app',anonymous=True)
    app = QApplication(sys.argv)
    app_widget = PythonAppWidget("PythonExampleApp",app)
    # Running
    rospy.logwarn("PythonExampleApp: Started")  
    app.exec_()
    # Done
    rospy.logwarn('PythonExampleApp: Finished')

# MAIN
if __name__ == '__main__':
  app = PythonExampleApp()

Highlights

This is where we inherit the base python application class and initialize it with super

class PythonAppWidget(ModulairAppWidget):
  def __init__(self,name,app):
    super(PythonAppWidget,self).__init__(name,app)
