Description
hello,
if i import the wx module in any python plugin under win 7 64bit and qgis 64 bit (master and 2.2 64bit), qgis throw the error below.
can anybody reproduce this error with my testplugin?how can i solve this problem?
there are no problems with qgis 32 bit (same master codeversion and qgis 2.2 32 bit).
thanks a lot :-)

what do you need wx for? wx is only included for the grass gui frontend - which QGIS doesn't even use.

I use wx for my communication interface (WM_COPYDATA) between qgis and other windows appliacations.
WM_COPYDATA Infos:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms649011%28v=vs.85%29.aspx
Here is a wiki python sample which i use to create my "communicationwindow":
import wx
class TestFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, wx.ID_ANY, title=title)
text = wx.StaticText(self, label="Hello World!")
app = wx.App(redirect=False)
frame = TestFrame(None, "A little example")
frame.Show()
app.MainLoop()

Wouldn't it be more handy to use Qt for that (ie. a window with winEvent in place)?

hello juergen,
do you have an example link for the solution with QT or are there alternative example code for communication interfaces between qgis and other windows applications?
but generally it's not possible to use wx under 64bit? why it works under 32 bit?
thank you

Sorry, I don't have a link. But I recently did it in a training.

Obviously it is - GRASS does it. Not sure if it's a good idea to mix toolkits and also why it doesn't work in 64bit, while it does in 32bit. But still it's sounds more like a edge-casy packaging problem - as said QGIS doesn't use wx.
thank you

Hello Jürgen,
The problem is now under qgis bit 32 in the current master on. You may be the reason the update of Qt to version 4.8.6? Is there a way the previous communication technology (WM_COPYDATA) to continue to use ?:
@import wx
class TestFrame(wx.Frame):
def init(self, parent, title):
wx.Frame.__init__(self, parent, wx.ID_ANY, title=title)
text = wx.StaticText(self, label="Hello World!")
app = wx.App(redirect=False)
frame = TestFrame(None, "A little example")
frame.Show()
app.MainLoop()@
32 bit

Still not a qgis issue.
Why insist on using wx inside of a Qt application if you can use Qt for the same thing (hint: derive from QDialog and implement winEvent; the incoming message can be decoded in python with ctypes; ctypes can also used to invoke sendMessageW)?
