Hi, All
I think I’v found the solution of my question.
Well, the secret is to use Layer() method.
Thanks to Andrea and *Vlastimil as well

Hi Paul,

I have been using FileConfig for a couple of small applications to

store, well, configs for XML-RPC details.

What I have found is that in some cases, it is necessary to touch the

filename like so:

def GetConfig(self):
   """
   Reads the config file for the application if it exists and
return a configfile object for use later.
   """
   if not os.path.exists(self.GetDataDir()):
       os.makedirs(self.GetDataDir())
   if not os.path.exists(os.path.join(self.GetDataDir(),
“chisimbauploader”)):
       open(os.path.join(self.GetDataDir(), "chisimbauploader"),
‘w’).close()
   config = wx.FileConfig(
       localFilename=os.path.join(self.GetDataDir(),
“chisimbauploader”))
   return config
in order for the config to get written on config.write()

This seems to happen spuriously, which leads me to believe that it may

be a bug.

Is this indeed the case?

I don’t know on which platform this happens and which wxPython version

you are using, but I use exactly the same code (except the “touch”) on

Windows XP for my GUI2Exe and everything works fine. As I know of some

user of GUI2Exe using GTK and Mac without issues with wx.FileConfig, I

don’t suppose a bug exists.

Anyone can help me?

If you use the AddPane call which uses the wx.aui.AuiPaneInfo class it

is much easier to layout your panes in the most complex ways you wish.

See the attached file.

HTH.

    ChangeValue
To: wxPython-users@lists.wxwidgets.org

Message-ID: 4912C9B9.7090403@free.fr

Having a problem when using numCtrl.ChangeValue(floatValue).

Problem can be demonstrated in the wxPython demo, change line 335, i.e.

From:
    try:

        self.target_ctl.SetValue(numvalue)

    except:

        type, value, tb = sys.exc_info()
To:
    try:

        self.target_ctl.ChangeValue(numvalue)

    except:

        type, value, tb = sys.exc_info()
I get a exception “TypeError: object of type ‘float’ has no len()” when

trying to use the combobox "Programmatically set the above value entry

ctrl" and having set the “Fraction width” to e.g. “2” and using one of

the float values.

Proposed correction is to add the following to wx.lib.masked.numctrl.py:
def ChangeValue(self, value):

    """

    Sets the value of the control to the value specified.

    The resulting actual value of the control may be altered to

    conform with the bounds set on the control if limited,

    or colored if not limited but the value is out-of-bounds.

    A ValueError exception will be raised if an invalid value

    is specified.

    """
dbg(‘NumCtrl::ChangeValue(%s)’ % value, indent=1)
    BaseMaskedTextCtrl.ChangeValue( self, self._toGUI(value) )
dbg(indent=0)

If above is o.k. could it be included with the next version? If yes,

should I submit a patch or is above fine?

Hi, all

This is a piece of sample code from aui.py.

My question is that when I run this code, I get a layout like this one,

but I need it like this, <[https://mail.google.com/ma=

il/?tf=3D1&ui=3D2&ik=3D462a71053d&view=3Datt&th=3D11d7108b7c624d1a&attid=3D=](https://mail.google.com/ma=il/?tf=3D1&ui=3D2&ik=3D462a71053d&view=3Datt&th=3D11d7108b7c624d1a&attid=3D=)

Hi,

I think, in this simple case using the following instead of the original

lines for adding the panes should do the trick:

self._mgr.AddPane(text1,

wx.aui.AuiPaneInfo().Left().Layer(1).Caption(u"Pane Number One"))

self._mgr.AddPane(text2,

wx.aui.AuiPaneInfo().Bottom().Layer(0).Caption(u"Pane Number Two"))

However, as there seem to be experts in AUI online, I’d like to ask a

related question regarding AuiManager:

Is it possible to set the dimensions of the docked panes (using

AuiPaneInfo() or otherwise - preferably, relative to size of the application

window?

Basically, I have a rather complex layout of panes in multiple columns and

their rows and I’d like to allmost hide the CenterPane filling the available

space with remaining panes.

It seemed to me, that the size… functions in AuiPaneInfo() all deal with

undocked panes, is it true?

Is there a way to set the columns to say 15, 1, 15, 15, 39 % of the

available width, then to divide the given column vertically in panes, e.g.

60, 30, 10 % of the height?

(I know, one can load the previously saved perspectives from a string, but

this isn’t usable for different monitor dimensions etc.)

Any help or hints would be much appreciated!

Thanks,

Vlasta

I think I might wait. But the funny thing is that even with wxPython

2.8.8.0 or 2.8.7.? this works without crashing on Xubuntu and on Suse

11.0 (tried with a LiveCD). And the Dabo developers can’t reproduce

the problem. That’s why I put all that version and use flag info into

my first post: I really think it’s my installation. Could it be that

I need a newer GCC version or something like that?

Possibly. There does appear to be some compiler specific situation here

as on Windows I was only able to duplicate it on the Py 2.6 version

which uses the MSVC 9 compiler, but not on 2.5 which uses the MSVC 7.1

compiler.

That’s interesting. Do I understand correctly: what you could duplicate on Windows with the new Python using the newer compiler, but not on the older configuration, was the crash? Very ugly!

For my Dabo dGrid problem I got a workaround, so that’s ok for now. I’m thinking of changing distributions anyway, Gentoo takes much time.

Thank you,

Sibylle

hi,

how can I create and start my work thread right after the gui main loop

started(when frame/main window shown). I need to start my work thread after

mainloop started because I need the value of the main window’s ID(got from

my_win.GetHandle() ) to initial/create the work thread instance, if I create

the workthread before the main_window shown, I’ll get the wrong value.

Best Regards,

Kevin
