Carbon Help

[TheShitX]

I need Help with carbon. I am running OS X 10.4 and i am using Xcode 2. I am having trouble because every time that I make an application there is an error with the Menus. I am inable to click them without the program issuing a warning:

ZeroLink: unknown symbol '__Z16doMouseDownEventv'

please could some one help me?

It means that you haven't defined

void doMouseDownEvent()

anywhere. Is that function in one of your source files? Is it in a C++ source file? Is the C++ source file in your project? Is it ticked for the target?

Sorry For the innapropriate name=(.

My code looks like this:

int main(int argc, char* argv[])
{

IBNibRef nibRef;
WindowRef window;
WindowRef window1;
EventRecord Event;
OSStatus err;
EventRef EvntRef;
EventHandlerUPP handlerUPP;
Boolean gotEvent;
err= CreateNibReference(CFSTR("main"), &nibRef);


err = SetMenuBarFromNib(nibRef,CFSTR("MenuBar"));
err = CreateWindowFromNib(nibRef, CFSTR("Window2"), &window1);
ShowWindow(window);
ShowWindow(window1);
SetPortWindowPort(window1);
gQuit=false;

while(!gQuit)
{
gotEvent = WaitNextEvent(everyEvent,&Event,MAX_UNIT32,NULL);
if(gotEvent)
{
doEvents(&Event);
}
}
return 0;
}


void doEvents(EventRecord * Event)
{

switch(Event->what)
{
case mouseDown:
doMouseDownEvent();
break;

case keyDown:
break;

case updateEvt:
break;

case autoKey:
break;

case activateEvt:
break;

case osEvt:
break;

case mouseUp:
break;
}
}

void doMouseDownEvent(EventRecord *EvtRec)
{
WindowPartCode PartCode;
WindowRef windowRef;
SInt32 menuChoice;

PartCode= FindWindow(EvtRec->where,&windowRef);

switch (PartCode)
{
case inMenuBar:
menuChoice=MenuSelect(EvtRec->where);
doMenuChoice(menuChoice);
break;

case inContent:
if (windowRef!=FrontWindow())
SelectWindow(windowRef);
break;

case inDrag:
DragWindow(windowRef,EvtRec->where,NULL);
break;

case inGoAway:
if (TrackGoAway(windowRef,EvtRec->where))
gQuit=true;
break;
}
}

void doMenuChoice(SInt32 MenuChoice)
{
MenuID menuID;
MenuItemIndex MenuItem;
OSErr err;
MenuCommand commandID;

menuID =HiWord(MenuChoice);
MenuItem = LoWord(MenuChoice);
}




*i have not finnished with the menu, this is just handles mouse down events so far.

Your function is doMouseDownEvent(EventRecord *EvtRec), but you're calling it with no arguments.

Thank you Very Much!! It works now! i had also declared it inproperly in the header file.
