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

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

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;

[Sam Spilsbury (smspillaz)]

Huh, that's weird. I've disabled META_HAS_LOCAL_MENUS here, and make sure to link to the system libmetacity-private and the tests are still passing for me.

Can you post the output of the individual tests before it reaches the point where they crash? Or do they just crash without outputting anything ?

(Could be something to do with the SetUp () function, so I'll give that a try

[Daniel van Vugt (vanvugt)]

Confirmed all unit tests now pass and no obvious bugs in manual testing.

I still think we need to be tidier with the CMake syntax as I've mentioned before...

review: Approve

[Sam Spilsbury (smspillaz)]

Yes, one day I'm going to introduce a bunch of functions to the CMake which reduce the verbosity.

Daniel - if you want to test this for realz, you can use the following:

lp:~smspillaz/metacity/metacity.lim
lp:~3v1n0/unity/lim-panel
lp:~indicator-applet-developers/indicator-appmenu/local-menus-single-menu
lp:~smspillaz/light-themes/light-themes.limv4

[Alan Griffiths (alan-griffiths)]

Looks OK, Builds OK, automated tests run. (With no META_HAS_LOCAL_MENUS)

review: Approve

[Marco Trevisan (Treviño) (3v1n0)]

I've tested it, to be even better, maybe you could also sync the title geometries once you opened/closed the menu, but that can be optional.
One thing you need to fix is the double-click over the title, that currently doesn't work as expected.
Look at the logic I've used in PanelTitlebarGrabArea.

Then I guess we need to define with design better one case: if a window is unfocused, and the user presses over the title / icon, should we just focus it or also open the menu? Currently we do both, but I'm not sure this is the best choice.

[Marco Trevisan (Treviño) (3v1n0)]

Ah, don't care about syncing geometries. You don't need that and could cause problems to the panel... :)

[Marco Trevisan (Treviño) (3v1n0)]

Ah, one more thing. Please check if the window you're decorating has the "_UBUNTU_APPMENU_UNIQUE_NAME" utf8 atom set to check if it has menus.

[Marco Trevisan (Treviño) (3v1n0)]

Ah, I forgot... The decorator is still missing to react to the com.canonical.Unity.Panel.Service.EntryActivateRequest signal, that happens when you do Alt+F on terminal for example... :)

[Sam Spilsbury (smspillaz)]

OK, I'll take care of these two things too. Thanks.

[Alan Griffiths (alan-griffiths)]

No obvious errors

review: Abstain

[Daniel van Vugt (vanvugt)]

Confirmed again all unit tests now pass and no obvious bugs in manual testing.

Though, like Alan, I have not reviewed the theoretical correctness of the code in detail.

review: Approve

[Marco Trevisan (Treviño) (3v1n0)]

Mostly it works, well.

By the way, I've tested the support for the EntryActivateRequest and even if it's correctly handled if a window is in focus (i.e. pressing Alt+F on the terminal causes the menu to show in the right place), otherwise if you have this scenario: a maximized window in focus, and a restored window unfocused, when pressing Alt+F (or something, that will be managed by the focused window) gtk-window-decorator crashes.

This is the stacktrace I have: http://paste.ubuntu.com/859831/
Actually you should just ignore that signal if no decorated window is in focus.

review: Needs Fixing

[Sam Spilsbury (smspillaz)]

Ack.

[Marco Trevisan (Treviño) (3v1n0)]

Crash fixed, it looks good to me now.

Unfortunately not all the apps yet supports the _UBUNTU_APPMENU_UNIQUE_NAME atom... So maybe for testing it could be temporary disabled (sorry). A temporary workaround could be this one: http://is.gd/IXPV4h

Grab buttons too so that we can process motion events on the titlebar and
move the window instead.

No obvious problems or regressions. And Valgrind is happy.
