[lmi-commits] [lmi] master 28b655c6 3/5: Show help output of wx_test under non-MSW systems

[Greg Chicares]

branch: master
commit 28b655c636d1ab0a5eacda531f6a5cd1c7f704f2
Author: Vadim Zeitlin <vadim@tt-solutions.com>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Show help output of wx_test under non-MSW systems
    
    wxMessageBox() cannot be used here under the non-MSW systems as the GUI
    is not initialized yet, so calling it resulted in output similar to the
    following when "wx_test --help" was executed:
    
    ...wx/src/gtk/msgdlg.cpp(278): assert ""m_widget"" failed in
    ShowModal(): failed to create GtkMessageDialog
    
    GLib-GObject-WARNING **: invalid (NULL) pointer instance
    
    GLib-GObject-CRITICAL **: g_signal_handlers_disconnect_matched:
    assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
    
    and no useful output.
    
    With this change, the expected message is shown on stderr instead.
