Hi
What sort of code do you mean?
It seems to be used to inform the system that Notification should be
shown.

Reading this
http://stackoverflow.com/questions/22142592/mac-os-usernotificationcenter-in-qt

Gives idea of how is constructed.

MyClass::MyClass()
{
    id<NSUserNotificationCenterDelegate> self = (id<NSUserNotificationCenterDelegate>)this;
    [[NSUserNotificationCenter defaultUserNotificationCenter] setDelegate:self]; 
}

BOOL MyClass::shouldPresentNotification(NSUserNotificationCenter *center, NSUserNotification *notification)
{
    return YES;
}

void MyClass::test()
{
  NSUserNotification *userNotification = [[[NSUserNotification alloc] init] autorelease];
  userNotification.title = @"Title";
  userNotification.informativeText = @"Test message";
  [[NSUserNotificationCenter defaultUserNotificationCenter] deliverNotification:userNotification];
}

Hi,

I can not declare in my H file follow line
BOOL MyClass::shouldPresentNotification(NSUserNotificationCenter *center, NSUserNotification *notification)
because if i add the follow line i got compilation error
#include <Foundation/NSUserNotification.h>

My pro file:
QT += core gui
TARGET = untitled
TEMPLATE = app
LIBS += -framework Foundation
INCLUDEPATH +=/System/Library/Frameworks/CoreFoundation.framework/Versions/C/Headers
SOURCES += main.cpp
HEADERS += mainwindow.h
mac
{
OBJECTIVE_HEADERS +=mainwindow.h
OBJECTIVE_SOURCES +=mainwindow.mm
}

How can i fix it?

@borisa said:

NSString

well u must find the .h file where its defined and include it.
update:
seems to be something else than pure .h file

so might be your XCode setup or SDK.

Hi,

Are you planning to use Objective-C++ or plain Objective-C ?
