quit an embedded viz-simulation

[levisii]

oh, i'm sorry. first time i'm posting here
i've splitted my code to one files per class, but if you run this, it is showing my problem:

import viz, wx

#This class implements the GUI-Frame
class MainFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)

        #Menubar
        menubar 	= wx.MenuBar()
        worldViz 	= wx.Menu()
        worldViz.Append(104, '&Simulation', 'Start a 3D-simulation')
        menubar.Append(worldViz, '&WorldViz')
        self.SetMenuBar(menubar)
        self.CreateStatusBar()

        wx.EVT_MENU(self, 104, self.onStart3D)

    #calls the embedded simulation
    def onStart3D(self, event):
        self.timer = wx.Timer(self, 5000)   #Timer for updating the frames
        self.timer.Start(10)
        wx.EVT_TIMER(self, 5000, self.onTimer)

        viz.go(viz.EMBEDDED)
        simulation()

    #Manuel FrameUpdate
    def onTimer(self, event):
        viz.updateframe()
        
#this is my test simulation
def simulation():
    viz.clearcolor(0.5, 0.5, 1.0)

    #Set ViewPoint
    view = viz.MainView
    view.setPosition(0, 1, -20)

    #Turn on the physics engine
    viz.phys.enable()

    #Add ground
    ground = viz.add('tut_ground.wrl')
    ground.collidePlane()

#Exit-function
def onkeydown(key):
    if key == '1':
        print 'onKeyDown() executed'
        viz.quit()

viz.callback(viz.KEYDOWN_EVENT, onkeydown)

def onexit():
    print'onExit() executed'
    viz.quit()

viz.callback(viz.EXIT_EVENT, onexit)


#this is the starting class
class MainApp(wx.App):
	def OnInit(self):
		frame = MainFrame(None,-1, 'Phantom')
		frame.Show(True)
		return True

app = MainApp(0)
app.MainLoop()
del app

Hello? Can anybody help me?

Are you trying to exit your entire application when the key is pressed, or just close the Vizard window?

If you are trying to exit the entire app, then you need to call the Close() method of your MainFrame class.

If you want to just close the Vizard window, then this is not possible. You can only call viz.go() once, so you can only create a single Vizard window for the duration of your script. To deal with this limitation you can create the Vizard window during startup and make the window visible/hidden to simulate creating/destroying the window.

Thank you very mutch for this information. It helps me a lot. I try to exit the Vizard window and create another one while the main frame is running. But I will handle this by antoher way.
