[GRASS-dev] Some wxPython 3 issues

[Markus Neteler]

Hi,

I have migrated my laptop from Fedora21 to F22 which comes with
currently wxPython-3:

GRASS version: 7.1.svn
GRASS SVN revision: 66061M
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: 3.8.10.2
Python: 2.7.10
wxPython: 3.0.2.0

There are a few issues with the wxPython 3 compatibility (I suppose):

- GUI startup: the splash screen has a top window frame now including
a minimizer (I think that was suppressed in wxpython2)

- WHile the GUI comes up ok, the following warnings appear at startup time:
(wxgui.py:9918): GLib-GObject-WARNING **: The property
GtkImageMenuItem:use-stock is deprecated and shouldn't be used
anymore. It will be removed in a future version.
(wxgui.py:9918): GLib-GObject-WARNING **: The property
GtkSettings:gtk-menu-images is deprecated and shouldn't be used
anymore. It will be removed in a future version.
(wxgui.py:9918): GLib-GObject-WARNING **: The property
GtkImageMenuItem:accel-group is deprecated and shouldn't be used
anymore. It will be removed in a future version.
(wxgui.py:9918): GLib-GObject-WARNING **: The property
GtkSettings:gtk-button-images is deprecated and shouldn't be used
anymore. It will be removed in a future version.
(wxgui.py:9918): GLib-GObject-WARNING **: The property
GtkAlignment:xalign is deprecated and shouldn't be used anymore. It
will be removed in a future version.
(wxgui.py:9918): GLib-GObject-WARNING **: The property
GtkAlignment:yalign is deprecated and shouldn't be used anymore. It
will be removed in a future version.

- the left-side tabs in the module windows do not have any
shade/border to distinguish them (the tab titles look ok and they are
clickable).

- the 2D/3D/v-r-digitizer switch is twice as long as needed: in effect
it is not visible unless the map display window is widened up
significantly to make it appear.

- temporal: the graphical representation opens but then gives this error:

Let me know which of this I shall report as tickets. Unfortunately I
don't know how to fix these issues.
