Menu Item DOM Node ID Notes
|

|
|
========================
|
|
= About This App = <- aboutName
|
|
= Check for Updates... = <- checkForUpdates
|
|
========================
|
|
= Preferences... = <- menu_preferences
|
|
========================
|
|
= Services > = <- menu_mac_services <- (do not define key equivalent)
|
|
========================
|
|
= Hide App = <- menu_mac_hide_app
|
|
= Hide Others = <- menu_mac_hide_others
|
|
= Show All = <- menu_mac_show_all
|
|
========================
|
|
= Quit = <- menu_FileQuitItem
|
|
========================
|
|
|
|
If any of them are ommitted from the application's DOM, we just don't add
|
|
them. We always add a "Quit" item, but if an app developer does not provide a
|
|
DOM node with the right ID for the Quit item, we add it in English. App
|
|
developers need only add each node with a label and a key equivalent (if they
|
|
want one). Other attributes are optional. Like so:
|
|
|
|
<menuitem id="menu_preferences"
|
|
label="&preferencesCmdMac.label;"
|
|
key="open_prefs_key"/>
|
|
|
|
We need to use this system for localization purposes, until we have a better way
|
|
to define the Application menu to be used on Mac OS X.
