wxPython and Flock of Birds

[Atul Thakur]

Hi:
Encountered another problem where I am trying to embed my script in wx and use the flock of birds. My script just hangs without throwing any error. Kindly point me to any example of such type. I searched but could not find.
regards,

PHP Code:

import viz, wx

viz.go(viz.EMBEDDED|viz.TRACKER)

class VizFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent, -1, "Virtual Training Studio - Training Module", size=(800,600),style=wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE)
        
        window = wx.Window(self,-1)
        
        #IMPORTANT: YOU MUST SET THE WINDOW BEFORE RUNNING ANY OTHER VIZ COMMANDS
        viz.setwindow(window.GetHandle())
        
        print "window setting"
        
        #IMPORTANT: SETUP A TIMER TO BE CALLED CONTINUOSLY, IN THIS CASE, EVERY 10 MILLISECONDS
        self.timer = wx.Timer(self, 5000)
        self.timer.Start(10)
        #self.Bind(wx.EVT_TIMER, self.OnTimer)
        wx.EVT_TIMER(self, 5000, self.OnTimer)
        
    
    def OnTimer(self, event):
        #IMPORTANT: YOU MUST MANUALLY UPDATE THE GRAPHICS FRAME
        viz.updateframe()
    
    def Quit(self):
        self.timer.Stop()
        self.Close()
if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = VizFrame(None)
    frame.Show(True)
    pos = [0,0,0]
    
    room = viz.add("room.wrl")
    room.translate(0,0,3)
    
    table = viz.add("table.wrl")
    table.translate(0,0,3)
    
    def onkeydown(key):
        if key == 'a':
            pos = sensor_obj.get(viz.EULER, viz.ABSOLUTE_WORLD)
            print pos
    viz.callback(viz.KEYDOWN_EVENT,onkeydown)
    
    PORT_FOB = 1
    BAUD_FOB = 115200
    sensor = viz.add('flockofbirds.dls')
    sensor.reset()
    sensor_obj = viz.add(viz.GROUP)
    sensor_obj.link(sensor)
    viz.tracker()
    app.MainLoop()

I ran your code and it didn't hang. What line of code is the script hanging on?

The code run fine if I comment out the fob invocation lines (PORT_FOB = 1 onwards till viz.tracker()).
But the code I posted hangs otherwise for me. On the Vizard output console I get
************************************************** ****************************
* VIZARD 2.53g *
* *
************************************************** ****************************

Loading File: room.wrl
Scaling image 'eastwall.jpg' from (1200,512) to (1024,512)
Loading File: table.wrl

And a gray window (not responding) pops up with hourglass cursor.

Actually, I am using FOB in a larger code and I figured out that this part is giving problem.

To be precise the code hangs on flg line
sensor = viz.add('flockofbirds.dls')

The flock is working fine otherwise on vizard (i.e.with other codes without wx)
