Openfile dialog and painting a picture

wxPython Users
1

ok, i’ll ask this better this time.

I’m trying to make a program that will open a bitmap file and paint it on the frame allow the user to draw rectangles on the picture giving the coordinates of the rectangle.

But first thing first. I can’t get the image to paint on the workspace without an error

Code as follows:

def OnOpen(self, event):
    dlg = wx.FileDialog(self, "Choose a picture", os.getcwd(), "", "*.*", wx.OPEN)
    if dlg.ShowModal() == wx.ID_OK:
            path = dlg.GetPath()
            self.SetStatusText("You selected: %s" % path)
    dlg.Destroy()
    self.Bitmap = wx.Bitmap(path)
    wx.EVT_PAINT(self, self.OnPaint)

def OnPaint(self, event):
    dc = wx.PaintDC(self)
    dc.DrawBitmap(self.bitmap, 1, 1)

any help would be great thanks

Hi guys,
    I have a really big big big problem with an external module:

BEFORE: I used python2.3, wxPython2.6 and PIL 1.1.4 ( and it's source code for building ). For my utility, I was build and external module defined _gauss with this distutils setup:

#!/usr/bin/env python

from distutils.core import setup, Extension

setup(name='_gauss', version='0.0.1',
      ext_modules=[Extension(
    '_gauss', ['_gauss.c'],
    extra_compile_args=['-I./Imaging-1.1.6/libImaging'],
    library_dirs=['./Imaging-1.1.6/libImaging'],
    libraries=['Imaging'],
    )]
      )

And it was build properly without any warnings/errors.

NOW: I must upgrade to python2.5, wxPython2.8 and PIL1.1.6.
When I run the script, it shows me this message:

    running build
    running build_ext
    error: Python was built with Visual Studio 2003;
    extensions must be built with a compiler than can generate
    compatible binaries.
    Visual Studio 2003 was not found on this system. If you have Cygwin
    installed,
    you can try compiling with MingW32, by passing "-c mingw32" to setup.py.

Well, I've installed mingw32, but, when it runs with: python _gauss_setup.py build -c mingw32

My gauss module utilize pil to draw, and it need Imaging, but I don't why this build don't work....
Any idea???

thx

It's saying that it can't find a library for the -lImaging arg. Did you also build PIL with this compiler? Did it produce a ./Imaging-1.1.6/libImaging/libImaging.a file?

NO!!! it doesn't produce this libImaging.a.
I remember that pil 1.1.4 required to enter libImaging directory and type ./configure and make
Here, in PIL 1.1.6 in libImaging directory it's not present...

How can i build this library???

thx
