Hi List,
I've built some pure java classes that use QTJava's
quicktime.std.music to implement a simple drum sequencer. I'd like to
build a Cocoa Java interface to edit drum sequences but I can't get
QTJava to run properly within Cocoa.
Specifically, the code compiles just fine, but the application hangs
whenever I try to call quicktime.QTSession.open() (the UI quits
responding to mouse clicks - menus, buttons, etc. stop responding).
Is QTJava incompatible with Cocoa, or is there some way to get QTJava
and Cocoa to work together?
I've been searching Apple's docs and the mailing lists for a solution,
but I've come up empty (the same problem was described in a 2001 list
mail, but no solution was posted).
http://sourceforge.net/projects/jmusic/
might be a an example. Looked to include some QTJava and indicated a
Cocoa UI.
I have some code to do some java to native interfacing of my own I
wrote or ported a couple sample/test classes that use QT movies. One
Cocoa to play mp3's and one sort of straight Carbon to play pdf's as QT
movies. This is neither 'real' Cocoa/java or 'real' QTJava. I access
both directly so I don't use the QTSession related which I think is a
QTJava specific wrapper or interface to Quicktime? Mine work afaik for
somewhat simplistic examples maybe. If you could point out some code
doing something similar to what you want, or yours isn't commercial and
you would care to share, I could take a look at it maybe.
