1. Can you point me to where it puts the UI inside the iTunes

Not sure what you mean by "putting the UI in the iTunes visualizer
window"? It doesn't - it creates a separate dialog window which seems
to be what all iTunes plug-ins do and are expected to do. You can
*draw* into the iTunes visualizer window of course, which is mostly
the point of them, but I don't put any UI there as such. You possibly
could, but never tried it.
In my mini-framework, the method to draw to the visualizer is
ITPlugIn::Render() - you override that to put your visual content into
the visualizer.
2. Also, how does one load a .nib from carbon?
One thing to clarify about Carbon vs. Cocoa - while Cocoa itself is
unavailable, you can of course use Core Foundation. However everything
in Carbon is lower level and generally more work than Cocoa, so be
prepared ;-)
Here's what I did - some vars referenced are data members:
void ITSpectrumAnalyserPlugIn::NewConfigDialog()
{
// default is to load dialog from NIB in bundle
IBNibRef nibRef;
//we have to find our bundle to load the nib inside of it
CFBundleRef iTunesXPlugin;
iTunesXPlugin =
CFBundleGetBundleWithIdentifier( CFSTR( "LEDSpectrumAnalyser" ));
if ( iTunesXPlugin )
{
CreateNibReferenceWithCFBundle( iTunesXPlugin,
CFSTR( "SettingsDialog" ), &nibRef );
if ( nibRef )
{
UseResFile( resFile );
CreateWindowFromNib( nibRef, CFSTR( "PluginSettings" ),
&configDialog );
DisposeNibReference( nibRef );
// if window was created, set up callback to handle its events. At
this stage we are only interested
// in control hit events
if ( configDialog )
{
static EventTypeSpec eventSpec[] = { kEventClassControl,
kEventControlHit,
kEventClassWindow, kEventWindowClose,
kEventClassTextInput, kEventTextInputUnicodeForKeyEvent };
InstallWindowEventHandler( configDialog,
NewEventHandlerUPP( DialogEventHandler ), 3, eventSpec, this, NULL );
}
}
}
else
SysBeep( 1 );
}
If you are in the Bay Area, CA, I will take you to lunch...
Thanks ;-) I'm in Australia....
