Using wx in Maya 2009

[highend3djojan-]

See code below: (dont remember my exact code!)

import wx

class MyApp(wx.App):

def __init__(self):
frame = wx.Frame(None, -1, "Hello")
frame.Show(True)
self.SetTopWindow(frame) # not important here??
return True

app = None
app = MyApp(0)
app.MainLoop()

It works fine in Maya. But viewport/outliner/channelbox/hypergraph/.... refreshing do not happen properly.

How can I overcome this issue?
(THANKS)

Or, can i save the Frame with current state, i.e; all widgets with current values (save current text of TextCtrl, like that)? If its possible, i can open the wx applicn only when necessary instead of minimizing, and Maya can be used with no issues since wx window is not active.
Please comment.

This is due to the Maya gui only using one thread, when your wxframe is active the thread is being used by your application. Autodesk have included a solution to this problem (albeit for qtToolkit and not wxpython) called pumpThread.py (located in the devkit/other folder in your maya install) its a massive hack but it works for qtToolkit and it could be tailored to work with wxPython.

I went thru pumpThread.py, and it helped. Thnx man! Gr8

But in this case, cant we use Maya commands, say to open new file in current Maya? (  mc.file(f=True,new=True)  )
See below code:

import wx, threading
import maya.cmds as mc

newThread = None
app = None

class MyApp(wx.Frame):

    def __init__(self, parent, id, txt):
        wx.Frame.__init__(self, parent, id, txt)
        wx.Button(self)
        self.Show(True)

        self.Bind(wx.EVT_BUTTON, self.OnClick)

    def OnClick(self, evt):
        mc.file(f=True,new=True)

def mainFn():
    global app
    app = wx.App()
    MyApp(None, -1, 'Hello')
    app.MainLoop()

def initializeNewThread():
    global newThread
    global app
    if newThread == None:
        newThread = threading.Thread( target = mainFn, args = () )
        newThread.start()

initializeNewThread()

Error when click button.
Plz help.

EUREKAA..!!
At last i got it..!
This is the code:

import wx, threading
import maya.utils as util
import maya.cmds as mc

newThread = None
app = None

class MyApp(wx.Frame):

    def __init__(self, parent, id, txt):
        wx.Frame.__init__(self, parent, id, txt)
        wx.Button(self)
        self.Show(True)

        self.Bind(wx.EVT_BUTTON, self.OnClick)

    def OnClick(self, evt):
        util.executeInMainThreadWithResult ( 'mc.file(f=True, new=True)' )

def mainFn():
    global app
    app = wx.App()
    MyApp(None, -1, 'Hello')
    app.MainLoop()

def initializeNewThread():
    global newThread
    global app
    if newThread == None:
        newThread = threading.Thread( target = mainFn, args = () )
        newThread.start()

initializeNewThread()
