hi there,
i was creating a frame with wxPython. from this frame i started an embedded viz-simulation. so far it works quite well. (i found everything i need here. thanks for that
)
but if i try to close this simulation and start it again form the mainFrame, the new simulation is just gray. the problem is that i am not able to call the viz.quit() function to clean up. as you can see in the code i was testing the function calls by printouts.
the viz.EXIT_EVENT is not executed before i close the wxPython mainFrame.
my onKeyDown() function does the test print as it should be done, but it ignores the viz.quit() without an error.
i hope you can help me.
here is my code:
#wxFrame class
import viz
import wx
import ducks #this is my testsimulation
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')
self.SetMenuBar(menubar)
wx.EVT_MENU(self, 104, self.onStart3D)
...
def onStart3D(self, event):
self.timer = wx.Timer(self, 5000) #timer to refresh the simulation
self.timer.Start(10)
wx.EVT_TIMER(self, 5000, self.onTimer)
self.sim = viz.go(viz.EMBEDDED)
test = ducks.simulation()
def onTimer(self, event):
viz.updateframe()
#my testsimulation class
import viz
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): #exit the simulation if you press 1
if key == '1':
print 'test'
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
import wx
from MainFrame import *
class MainApp(wx.App):
def OnInit(self):
frame = MainFrame(None,-1, 'Phantom')
frame.Show(True)
return True
app = MainApp(0)
app.MainLoop()
del app
