[platform-swt-dev] Mac OS X application menu?
|
I'm pretty new to SWT. I'm trying to get it to work on Mac OS X in iRATE radio:
http://irate.sourceforge.net/
I followed the instructions in Eclipse bug #40003. It mostly works well.
However, Mac OS X adds an extra menu in addition to the ones created by the java
app. Apple calls it the Application Menu. In iRATE, the menu has the title
"iRATE radio". The menu is not present on other platforms like Windows and Linux.
The problem I have is that the application menu's Quit item doesn't work right.
iRATE's window disappears, as do most of its menu titles, but the application
menu is still present, and iRATE continues playing its audio (it is an MP3
downloader and player).
You can try out what I have so far, with the broken quit menu, at:
http://irate.sourceforge.net/download.unstable.html#osx-swt
I have found two ways for Java apps to deal with the application menu, but
neither works for me. The first, which is deprecated, is to install a
com.apple.mrj.MRJQuitHandler:
http://developer.apple.com/qa/qa2001/qa1187.html
the new way is to use the com.apple.eawt.Applicaton singleton, with which I
install a com.apple.eawt.ApplicationListener (or rather a class that implements
that interface).
If I do either one, iRATE never shows any of its UI. I have to forcibly
terminate it. There are no error messages to the console.
I suspected Apple's platform-specific packages might be using AWT, so I followed
the instructions at the bottom of bug #40003, and called:
System.setProperty( "java.awt.headless", "true" );
This seemed to verify that Apple was indeed using AWT, in that it allowed iRATE
to start up and work. But again the Quit menu didn't work.
Could the application menu actually be created by SWT? If so, what do I need to
do to handle it? Or is there something else I need to do.
