[GRASS-dev] Some wxPython 3 issues

[Vaclav Petras]

My system is:

GRASS version:
7.1.svn
GRASS SVN revision:
66067M
Build date:
2015-08-29
Build platform:
x86_64-unknown-linux-gnu
GDAL:
1.11.2
PROJ.4:
4.8.0
GEOS:
3.4.2
SQLite:
3.8.7.4
Python:
2.7.9
wxPython:
3.0.1.1
Platform: Linux-3.19.0-26-generic-x86_64-with-Ubuntu-15.04-vivid

Splash is fine for me. Just the image.

GUI start error/warning messages:

/usr/share/themes/Lubuntu-default/gtk-2.0/apps/thunar.rc:55: error: invalid
string constant "thunar-statusbar", expected valid string constant

As using the GUI I get also:

(wxgui.py:7668): Gdk-CRITICAL **: IA__gdk_window_thaw_updates: assertion
'impl_window->update_freeze_count > 0' failed

I'm not sure how exactly you see the left-site tabs but mine are just fine.

Switch for 2D/3D/r/vdigit OK, although hidden when window is too small
(while toolbar buttons are nicely available under an arrow at the end of
the toolbar as a menu with descriptions such as printMap and saveFile).

Timeline tool opens without any error but not tested with data.

You have wxPython 3.0.2.0, I have 3.0.1.1. I'm using Lubuntu 15.04 which
means LXDE and Openbox. I don't know if this has some influence. Here are
my precise versions of wxPython and matplotlib (both inside and outside of
GRASS):

$ python -c "import wx; print(wx.version()); print(wx.__version__)"
3.0.1.1 gtk2 (classic)
3.0.1.1
$ python -c "import matplotlib; print(matplotlib.__version__)"
1.4.2

But unfortunately, I must say, I have a lot of other problems especially
with text inputs but the issues are similar to the ones in some of the
other applications, so that's probably something with the libraries which
should be solved.
