Mac-style Menu Bar for GTK and Java/Swing applications!

[ayoli]

Hey! I love your work but unfortunatey, it seem to have a few kinks...
Gnome's Macmenu application seems to break xaralx.
Could it be some weird conflicting dependencies?

XaraLX crash dump:

Steps to repeat: with macmenu installed,
fire up xaralx.
Select an option that requires a dialog box (File->Page Options; File->Print Options; Utilites->Options)
Strangely, the "import", "export", and "open file" dialogs work fine...
Observation: XaraLX closes without warning.

I want to blame libpango for it, but obviously I don't know the inner workings of Gnome...
If it's not libpango, it might be libgtk2.0-0, but trying to downgrade it back to 'gutsy' messes a lot of things that have nothing to do with the macmenu at all... like beep-media-player, for example...
Anyone knows what libraries are affected by macmenu that could have this adverse effect?

No, I don't know what libs could be related to this.
But you can disable macmenu for this app using the GTK_MENUBAR_NO_MAC environment variable.

[Tiede]

Thanks for the quick reply, ayoli.
Unfortunately, using that does not undo the damage...
I may need to uninstall macmenu completely and deal with the broken packages myself afterwards.
What I did:
created a file named .gnomerc in my home folder.
edited the file with the text

export GTK_MENUBAR_NO_MAC=1

logged out and back in gnome.
result:No change, xaralx still crashes.
I'm wondering whether i am blaming the wrong app, but the problem is that was the only thing I added and/or updated before the app started acting weird... Should I file a bug against xaralx, macmenu, both?

***EDIT***
The problem aforementioned is entirely unrelated to macmenus, and was a mistake on my part. Thanks ayoli for helping me figure it out. Besides, an entry about my problem is posted elsewhere on the forums...

Using a patched gtk with GTK_MENUBAR_NO_MAC=1 is like using a non patched gtk so, the bug must come from the app I mean xaralx).

Good news, a testing process is being done as part of the Google Highly Open Participation Contest.

Sorry, I can't modify the wiki. I am not a ubuntu user and I don't have a launchpad account.

[Kimmik]

AAHHH!!!

Warning!
I used the howto in the wiki to install the .debs and it messed my system up!!

Before installing the .debs make sure that you have activated the backports in synaptic! Because you need libpango1.0-0 version 1.18.3.

Hi folks!

I'm doing the testing on the Global Menu Bar for the Google Highly Open Participation Contest.

Rather than sort through all 100+ pages of this thread, I thought I'd ask what some common problems/bugs people have seen with the Menu Bar so I can try and replicate em'.

I already have a short list of my own:

• The Mac Menu Bar and the User Switch applet do not agree with each other
• The far right side of the Menu is statically attached to the right side of the Panel
• The height of the menu is static, so when the Panel is too large it leaves space around the menu buttons (A problem shown by Fits' Law)
• Menu does not show at all when the panel is on the right or left side of the screen.
• The right side of the menu distorts when being moved
• Changing the background of the panel has no effect on the menu.

Also, I just followed the instructions (click here) to install. Is this the latest version, or have any patches been created?

with a little work, this could be a very solid and useful piece of software. I hope I can help!

[rainwoodman]

Hi everyone,

I located a few bugs and made
some fixes for gnome-macmenu-applet with scrolling:

* Fixed the random seg faults when removing the applet from panel. (hopefully)
+when quiting, disconnect signals(desktop signals and socket signals) before destroying private data structures.

* Fixed the dull app title label(last time it always display GNOME)
* Move the menubar a little bit higher, so that clicking the top of the screen will also emit the menus.

The patched source and a source rpm is provided.

[mangar]

wiki edited, thanks rainwoodman!
we really need some sort of svn/ git/ whatever...

preliminary code review:
1. hard coded application name exceptions are bad..
2. MacMenu --> GlobalMenu.
3. some functions are too big.

[rainwoodman]

@mangar
Yes. you are right, a svn will be very helpful.

I am going to learn some XML programming and see if I can remove the hard code part.

I know nothing about XFCE developing, so the XFCE part of the code perhaps have already been messed up.

Another big problem is gtk_socket_steal is inherently unreliable and is deprecated, according to the gtk documentation. A fix for it requires modifying the gtk-menubar patch, making it to expose the menubar through a hidden GtkPlug object, and to store plug's window id somewhere where gnome-macmenu-applet can access(perhaps by calling a dbus method exposed by the applet?). I can't find a easy way to debug gtk2, so this fix will be impossible by now.

I wonder if a rewriting of gnome-macmenu-applet(rename to gnome-globalmenu-applet, wipe out the XFCE code, XMLize the name translation, leave space for GtkPlug) is necessary.

Also, it is very annoying that I can't read the stderr and stdout of the applet. Even if I start gnome-panel from a terminal, it outputs nothing. Do you/anybody else have some idea to reach the streams?
