BridJ: add support for Objective-C blocks (closures)

See example use case provided by Andrei Sochirca in issue #188 :

NSEvent.addGlobalMonitorForEventsMatchingMask(mask, block)

Copied from original issue: nativelibs4java/nativelibs4java#192

Hi Andrei,

I've reached a first stable state for Objective-C 2.0 blocks support : it's very similar to callbacks, except you inherit from org.bridj.objc.ObjCBlock instead of org.bridj.Callback (please see ObjectiveCTest in the commit diff to see an example of usage).
Please feel free to open issues on this feature if you find any (the way BridJ supports blocks is... a hack, as usual :-)).
(I'm uploading a new 0.6-SNAPSHOT right now)

Cheers

Hi Olivier,

Great! Thank you very much!
I will check it during next week.
Are there any news regarding Objective-C delegate support? :)

Regards, Andrei.

Hi Andrei,

Have limited time resources here unfortunately, so issue #188 hasn't progressed much (although its automated tests run fine : you can help improve them to point me to the right direction).

Cheers

Hi Olivier,

I understand.
As to #188, I've mentioned QTKit - based example (http://download.smaxe.com/bridj_test-111020.zip (class TestQT)).

In this example, video capture is started but delegate class is not notified about next video frame.
I will check the latest bridj version.. may be something did change :)

Regards, Andrei.

Hi Olivier,

Does ObjectiveCTest#testGlobalNSEventHook() work in your environment?

hi,

how is this issue?

i'm now implementing about obj-c blocks on my forked rococoa project.
somehow i could implement working obj-c block mechanism.
but it works only for methods which i made. it doesn't work for methods which are apple provided.

here is my stuck summary
and code

could you tell me why do you currently stop releasing about obj-c block
and your insight about my stuck would be much appreciated.

and also it's sad that pyobjc can do it but java can't.

thanks
