Merge lp:~smspillaz/compiz-core/compiz-core.lim into lp:compiz-core

[Sam Spilsbury]

Adds support for Ubuntu's "locally integrated menu bars" into gtk-window-decorator.

No tests as of yet, but I'll try and write some for

showing/hiding
forcing them on/off
positions etc

soonish.

8 +#define GWD_SHOW_LOCAL_MENU (WNCK_WINDOW_ACTION_BELOW << 1)

No plausible reason for using a macro. In C++ constants (enum or unsigned int) are better as they respect scope rules. Also, should this be inside "#ifdef META_HAS_LOCAL_MENUS" conditional?

296 button_layout->right_buttons[2] = META_BUTTON_FUNCTION_CLOSE;
297
298 - for (i = 3; i < MAX_BUTTONS_PER_CORNER; i++)
299 + for (i = 4; i < MAX_BUTTONS_PER_CORNER; i++)
300 button_layout->right_buttons[i] = META_BUTTON_FUNCTION_LAST;
301 }

I'm not sure what the magic number "3"->"4" is. But we now seem to miss 3 entirely. Is that correct?

Its for initializing the array, though maybe thats wrong. Good find let me check

+ gboolean empty = g_strcmp0 (entry_id, "") == 0;

You can do the same with:
gboolean empty = (!entry_id || entry_id[0] == '\0');

[Alan Griffiths (alan-griffiths)]

If we're trying to be cryptic...

   gboolean empty = g_strcmp0 (entry_id, "") == 0;

can be written:

   gboolean empty = !entry_id || !*entry_id;

[Marco Trevisan (Treviño) (3v1n0)]

Ah, Sam remember to update the "EntryActivated" signal against the new signature s(iiuu).

[Sam Spilsbury (smspillaz)]

Yep, done
