Hi!

I am in the process of wrapping Objective-C/Cocoa code into a Mach-O

doing it? If not, is there a different or better way?


I created a Cocoa Bundle - which I load into my Carbon app.
I just followed these instructions...

http://developer.apple.com/documentation/Cocoa/Conceptual/ DisplayWebContent/Tasks/CarbonApps.html http://developer.apple.com/documentation/Cocoa/Conceptual/ CarbonCocoaDoc/cci_chap3/chapter_3_section_2.html http://developer.apple.com/documentation/Cocoa/Conceptual/ CarbonCocoaDoc/cci_chap2/chapter_2_section_1.html

... made a first working dummy and then specialized it for my needs. It was a stoneless way so far - just the problem I described in my other mail.

2) When I receive an event through a WebView delegate I do not exactly
know what the best way is to inform my Carbon app. Today I create a
command event with some parameters and send it to my app. Is this the
nicest way to go? How can I do this more elegant.

What exactly do you mean by "command event"?


I ment the other way arround - receiving events from the Cocoa WebKit.
Something like this (out of my Cocoa Bundle):

void SendCommandProcessEvent(UInt32 theCommandID, HIViewRef theCarbonRef, int theError, NSString* theString) { HICommandExtended aCommand; EventRef anEvent;

// Parameter speichern SetControlProperty(theCarbonRef, theCommandID, 'int1', sizeof(int), &theError); SetControlProperty(theCarbonRef, theCommandID, 'str1', ([theString cStringLength] + 1), [theString cString]);

    // Event senden
    BlockZero(&aCommand, sizeof(aCommand));
    aCommand.attributes = kHICommandFromControl;
    aCommand.source.control = theCarbonRef;
    aCommand.commandID = theCommandID;

    (void) CreateEvent(
        NULL,
        kEventClassCommand,
        kEventCommandProcess,
        GetCurrentEventTime(),
        kEventAttributeUserEvent,
        &anEvent
    );
    (void) SetEventParameter(
        anEvent,
        kEventParamDirectObject,
        typeHICommand,
        sizeof(aCommand),
        &aCommand
    );
    (void) SendEventToApplication(anEvent);
    (void) ReleaseEvent(anEvent);
}

Best,
Marcel
