Subject: Windows: PyHoca-GUI fails to start (ImportError: No module named wx)

Date: Sat, 5 Jul 2014 09:46:24 -0400

[Message part 1 (text/plain, inline)]

package: pyhoca-gui
version: 0.5.0.0-preview

For some reason I cannot figure out, on my home desktop (Windows 8.1
with update 1 64-bit) I experience the error below when I try to
launch PyHoca-GUI in development mode.

I have not been able to testPyHoca-GUI in regular/installed mode due to #531.

Yet on the X2Go-WinBuilder VM (Windows 7 64-bit SP1,) which I am
almost certain I did the same exact setup work on (according to the
instructions immediately below), it does not have the problem. It
launches pyhoca-gui successfully.
http://wiki.x2go.org/doku.php/wiki:development:build-howto-mswin:pyhoca-gui

I've attached a 1 line fix. I'd like to discuss it before I commit it.

IMHO you have to make sure that the correct wx version is loaded.

So if we place an "import wx" into pyhoca-gui(.exe), we should make  
sure the correct wx.version is used. So "import wx" needs to be blown  
up to:

"""
try:
    import wxversion
    wxversion.select('2.9')
except: pass

try:
    import wxversion
    wxversion.select('2.8')
except: pass

import wx
"""

If that fixes the problem on Windows, I am happy with these extra  
lines in pyhoca-gui. (Please accompany those lines with a comment that  
explains, why the import occurs there, although the wx module is not  
used in pyhoca-gui(.exe) directly (but only in submodules).

Actually, on both machines, I installed wxPython 3.0.

Is 3.0 OK? Or should I downgrade them to 2.9?

X2Go Component: src:pyhoca-gui
Version: 0.5.0.0-0x2go1
Status: RELEASE
Date: Mon, 20 Oct 2014 12:51:05 +0200
Fixes: 19 394 460 507 533 534 548
Changes: 
 pyhoca-gui (0.5.0.0-0x2go1) RELEASED; urgency=low
 .
   [ Mike Gabriel ]
   * New upstream version (0.5.0.0):
     - (Now really) Support Python wxWidgets 3.0.
     - Add X2Go Session Broker support.
     - Adapt to new backend concept found in Python X2Go (>= 0.5.0.0).
     - Move most code of the pyhoca-gui executable into a dedicated class
       named PyHocaGUI_Launcher.
     - Allow automatic image branding (splash, about image, tray icon) by
       setting another application name than the default.
     - Rename icon files to match default application name (PyHoca-GUI).
     - Make default cmdline option parameters overridable before the
       arg parser gets initialized.
     - Make SCRIPT_NAME in setup.py configurable (monkey-patchable).
     - Make setup.py importable, only run setup() function on direct calls.
     - Don't refer to py2exe anymore in nsis_template's naming scheme.
     - Provide separate mswin_logging module.
     - Install more modules into setup.exe: hmac (for ecdsa).
     - NSIS script: empty installation destination before installing new files
       into $INSTDIR.
     - Allow appname based mini icons on About... windows.
     - Make the hover text of the tray icon brandable (drop hard-coded
       PyHoca-GUI application name).
     - NSIS script: make sure SetOutPath gets called at the beginning of
       every section.
     - Show printing preferences when tray icon is in restricted mode.
     - Session profile manager: the host parameter will be of type ListType
       for future versions of Python X2Go (>= 0.5.0.0).
     - Focus the user name field on logon if no user name is stored in the
       session profile.
     - Re-order cmdline sections (man page, defaults.py).
     - Optimize menu rendering. Reduce accessing session profile data as best
       as is possible.
     - Provide cmdline option --broker-cacertfile. Enable https:// connections
       with SSL certificates that have been self-signed against a non-public
       root-CA certificate file.
     - Handle "Connection refused" errors during broker login attempts.
     - Gracefully handle "Connection refused" errors after a broker login has
       already been successful.
     - Properly set focus in broker logon window (default: password, if no
       username
       provided: username, if no URL provided: broker-URL field).
     - Fix check_running() method in PyHocaGUI_Launcher on MS Windows.
     - Make broker support available for the MS Windows build of PyHoca-GUI.
     - Make check_running() test terminal server / multi-session safe.
       (Fixes: #19).
     - Windows PyHoca-GUI.log file: create with PID in file name. On log file
       creation try removing all old log files that are not still open.
     - Create Windows log file folder before attempting clean up (old log file
       removal).
     - Make sure new session profiles are mutable in the session profile manager
       GUI.
     - Gray-out Apply button in session profile GUI on profile creation.
     - Windows builder: Explicitly add the requests module to the set of
       bundled Python modules.
     - In session profile manager GUI: handle multiple clicks on the Apply button
       gracefully.
     - Notification about multiply started PyHoca-GUI instances. Don't hard code the
       application name.
     - Fix path name detection for default icons. (Fixes: #394).
     - Update English / German translation.
     - Add subsystem string support for HOOK_forward_tunnel_setup_failed hook.
     - Improve NX performance by reducing reactivity of wx widgets.
     - Grey-out all SSH related options for DirectRDP sessions.
     - Make the clipboard mode configurable through the session profile manager
       window. (Fixes: #507).
     - Make the published applications menu tree more robust against unknown
       icon image types.
     - Prepare for running against wxPython 3.0. More testing needed. (Fixes:
       #534).
     - Rename LICENSE.txt to COPYING.
     - Add Keywords= field to pyhoca-gui.desktop file.
     - Don't flood PyHocaGUI._eventid_(uns)hared_folders_map dict with
       non-valid-anymore event IDs.
     - pyhoca-gui.desktop: Set Categories: to Network;RemoteAccess;.
     - setup.py: Install .mo files into DESTDIR.
     - brokerlogin.py: Fix parameter error when evoking message box.
     - More reliably handle errors in a given --broker-url option value.
   * debian/control:
     + Add D (bin:package pyhoca-gui): python-cups. (Fixes: #460).
   * pyhoca-gui.spec:
     + Adapt to building on openSUSE/SLES.
     + openSUSE has python-notify whereas Fedora/RHEL has notify-python.
     + openSUSE (at least >= 12.3) has wxPython 2.9. So let's use it. (On openSUSE
       13.1, pyhoca-gui segfaults with wxPython 2.8).
     + Try to build the .po -> .mo files during package build.
     + Install locale files into bin:package.
     + No extra BR on gettext, intltool will pull it in anyway.
