The studlyCaps naming conventions conflict with the standard GNU, Gnome and GTK
naming conventions.

Consider a custom Frame class (Gtk::Frame style). It would have the following
methods:

void setFrameWidth(guint width); // workrave method
void set_border_width(guint width); // inherited method
void setFrameStyle(Style style);
void setFrameColor(Gdk::Color color);
void setBlinking(bool);

IMHO, the above is bad for code readability (and butt-ugly ;-)

Solution:
  
void set_frame_width(guint width); // workrave method
void set_border_width(guint width); // inherited method
void set_frame_style(Style style);
void set_frame_cColor(Gdk::Color color);
void set_blinking(bool);

I hereby request humble permission to use the latter set of API names for my
custom frame class, and gradually phase out all studlyCaps.

Uhh. If your class behaves like a gtkmm class, it might as well look like one.
So,  I don't mind the underscores. 

Still not realy conviced about converting everything to underscores...can it be
done (semi-) automatically ?

Sure. A couple of lines of perl doing:

1) destudlify.pl `find . -name '*.cc'`  :

foreach (@ARGV)
{
  // collect \1 in "Class::(fooBar)" where fooBar != Class
  collect_all_symbols_for_file($_);  
}
foreach (@ARGV)
{
  destudlify($_);
}


2) while (! compiles_error_free()) { edit; make; }

I am volunteering. 

Be my guest. Just to be sure: only underscores for methods and variables. Class
names and filenames remain studly. Ok ?

Please add a CVS tag before performing an automatic mass-rename. Just in case...

(I seems that almost all my pre-workrave code uses underscores....Damn coding
standards at work...)

Constants are still in error:
  enum Command
    {
      CmdNone,
      CmdUpdate,
      CmdTimerAction,
      CmdTerminate
    };
What coding standards prescribe the above? (Java doesn't).

Correct (Java/GTK/GNOME) would be:


  enum Command
    {
      CMD_NONE,
      CMD_UPDATE,
      CMD_TIMER_ACTION,
      CMD_TERMINATE
    };

What do you think, Rob?

Some constants already use all-caps. fixing.

Fixed
