    Hi,
     
    I'm using Fedora 16 with wxPython 2.9.3.1 and I'm having problems setting a
    textctrl to be multiline. It works fine on both Windows 7 and Fedora 16 if
    I do this...
     
    text = wx.TextCtrl(frame, -1, 'test', size=(200,200), style=wx.TE_MULTILINE)
     
    However, if I do it this way it only works on Windows 7 but throws
    errors/warnings on Fedora 16...
     
    text = wx.TextCtrl(frame, -1, 'test', size=(200,200))
    text.SetWindowStyle(wx.TE_MULTILINE)
     
    This is the warning I get on Linux...
    (debug.py:2094): GLib-GObject-WARNING **: invalid cast from `GtkEntry' to
    `GtkTextView'
     
    I first noticed this using XRC to define a textctrl to be multiline but it
    threw a different message on Linux...
    wx._core.PyAssertionError: C++ assertion "IsSingleLine()" failed at
    /tools/wxPython-src-2.9.3.1/src/gtk/textctrl.cpp(828) in GetEditable():
    shouldn't be called for multiline
     
    Am I doing something wrong here?
     
    Thanks,
    Adam

    I'm guessing there are two different widgets on Linux whereas on Windows,
    it's just one. Thus you probably have to instantiate it one way or the
    other, not change it after it's been created. We'll see if my hunch is
    right when Robin jumps in here...

    Hi All,
     
    I had a problem which occurred with the wxPython demo that highlighted a
    problem with wxConfig - when the demo had a problem reading the config
    file it displayed a message, giving me the path and a details button -
    the only trouble is that the error box only persisted for a few seconds
    - presumably until the application terminated - this was not long enough
    to read the file path. Once I had managed to find the faulty file I
    just needed to rename it to get things running again but I had to try
    running the demo 5 or 6 times before I saw enough of the path.
     
    Is there any way of, when an error is displayed, waiting until the error
    has been read by the user before terminating the application - e.g.
    making the error dialogue modal and giving it a go away button, (OK or
    Cancel), in the case of a fatal error like this?
     
    I am sure that I have seen errors like this before with other wx based
    applications and they have been known to make an application unusable.
    Even worse uninstalling the demo and reinstalling it - my first option -
    didn't remove the configuration file that contained the fault.
     
    wx python version 2.8.12.1 (msw-unicode)
    demo version ditto.

    I gave it a try and implemented it in SVN. Could you test it and see
    if it works?

    Bad attempt. Shame on me for not testing it... I'll fix it when I get
    back home tonight :-(

    Chris,
     
    I think the problem is in data order. Even in the code (link posted), at
    the bottom, before writing png image, some manipulation is going on but not
    able to understand it correctly.
    Thanks for pointing out "result[1]" mistake, unfortunately it didn't helped.
     
    Yes, Cython recently added support for array.array. I'll look into this
    later.
     
    Robin,
     
    I changed to char array instead of python's list, it works but results are
    pretty much same.
     
    Cheers
     
    Prashant

    Ah, I just noticed that you seem to be adding 4 values per pixel, 3 for
    RGB (presumably) and 1 with a constant value of 255 for the alpha
    (presumably). I only noticed the 1st 3 lines before. If that is your
    intent then you should be using wx.BitmapFromBufferRGBA instead of
    wx.BitmapFromBuffer, and use width*height*4 instead of the *3 I
    mentioned before. Also you should double check that the values you are
    fetching from the source buffer are in RGB order.

    Thanks Robin,
     
    Using wx.BitmapFromBufferRGBA, every thing is working fine.
     
    Cheers

    Yes it is/should be see the demo for splitter window - that logs every
    time the focus moves from the window(s) of the application to something
    else.
