Error on "Display Map" in wxpython

[cnielsen]

When I click display map in wxpython, nothing happens. The following error appears in command output: Traceback (most recent call last):

File "c:\Programs\GIS\osgeo4w\apps\grass\grass-6.5.svn\etc

\wxpython\gui_modules\mapdisp.py", line 541, in OnDraw?

return _gdi_.PseudoDC_DrawBitmap(*args, **kwargs) TypeError? : in method 'PseudoDC_DrawBitmap', expected argument 3 of type 'int'

This is a build of develbranch_6 within the osgeo4w tree on vista.

As point of reference, 6.4.0RC3 worked fine.

Same error occurs on trunk

[cnielsen]

Still no resolution to this bug, perhaps it relates to the change from mapdisp.py

pdc.DrawBitmap(bitmap, coords[0], coords[1], True) # draw the composite map

To mapdisp_window.py:

pdc.DrawBitmap(bitmap, wx.Point(coords[0], coords[1]), True) # draw the composite map

The error says "expected argument 3 of type 'int'" and it seems that it is still looking for "coords[1]" when in the latter case it is instead getting "true" since "coords[1]" has been put within wx.Point as part of arg 2.

Trying to trace this back I noticed that the grass-6.5.svn/etc/wxpython/vdigit folder is empty. Apparently vdigit isn't compiling at all. Ideas?

[cnielsen]

I found the README, apparently I need --python and --wxwidgets. If I'm understanding this correctly, this ticket should probably be closed.

[cnielsen]

On second thought, you shouldn't need (and didn't need before) support for vdigit just to display a map. It seems that it got incorporated as a requirement rather than an option somewhere along the line.

That ticket includes information about vdigit and nviz but they're still not functioning in the osgeo4w builds right?

Do I need to run package.cmd to make a functioning GUI? If so I'm missing h:\windows\wxPython-src-2.8.9.1 and my attempts to get it from the wxpython/wxwidgets svn were unsuccessful...

I'm still missing something, but I see that you didn't need --python or --wxwidgets in your osgeo4w builds.

Yes.

That's the wxPython build. I started off with  http://www.wxpython.org/download.php#binaries there (including the devel packages), but IIRC I couldn't get the libraries to work.

So I resorted to building wxPython with VC++ 2008 Express Edition - leading to the described problems. Later I tried with VS2003, which didn't significantly changed anything.

Exactly. GRASS is not aware of distutils, which AFAIK should be used to build python extensions.

build script package.cmd for wxPython:
