在 Qt/Cocoa 中获取 AppleEvent

发布于 2024-12-12 01:03:47 字数 812 浏览 0 评论 0原文

我有一些 Qt 4.4/Carbon 代码，可以很好地获取 Mac OS X 文档打开事件（例如，用户双击与应用程序关联的文档）：

#ifdef Q_OS_MACX
#include <Carbon/Carbon.h>
#endif

MyApplication::MyApplication( int& argc, char** argv )
:QApplication( argc, argv )
{
#ifdef Q_OS_MACX
    AEInstallEventHandler( kCoreEventClass, kAEOpenDocuments,
     TPApplication::appleEventHandler, 0, false );
#endif
}

MyApplication::~MyApplication()
{
#ifdef Q_OS_MACX
    AERemoveEventHandler( kCoreEventClass, kAEOpenDocuments,
     TPApplication::appleEventHandler, false );
#endif
}

#ifdef Q_OS_MACX
OSErr 
TPApplication::appleEventHandler( const AppleEvent* ae, AppleEvent*, long )
{
    // process events
}
#endif

我想将此代码移植到 Qt 4.7/Cocoa。是否仍然可以从基于 Cocoa 的 Qt 应用程序调用此代码，或者我是否必须调用 Cocoa API？或者是否有更优雅的方法来拦截用户双击与应用程序关联的文档，而无需特定于平台的代码？

I have some Qt 4.4/Carbon code that works fine for getting Mac OS X document open events (e.g. user double clicks on document associated with app):

#ifdef Q_OS_MACX
#include <Carbon/Carbon.h>
#endif

MyApplication::MyApplication( int& argc, char** argv )
:QApplication( argc, argv )
{
#ifdef Q_OS_MACX
    AEInstallEventHandler( kCoreEventClass, kAEOpenDocuments,
     TPApplication::appleEventHandler, 0, false );
#endif
}

MyApplication::~MyApplication()
{
#ifdef Q_OS_MACX
    AERemoveEventHandler( kCoreEventClass, kAEOpenDocuments,
     TPApplication::appleEventHandler, false );
#endif
}

#ifdef Q_OS_MACX
OSErr 
TPApplication::appleEventHandler( const AppleEvent* ae, AppleEvent*, long )
{
    // process events
}
#endif

I want to port this code to Qt 4.7/Cocoa. Is it still possible to call this code from a Cocoa based Qt app, or do I have to call the Cocoa API instead? Or is there are more elegant way to intercept the user double clicking on a document associated with the app without platform specific code?

我有同样的问题。我不确定，但我认为它确实有效。但从不同的侧面来看一下。为什么要保留遗留代码？ Carbon API 不是 64 位。迁移此代码应该不难（检查 NSAppleEventManager）。

这是注册方式：

NSAppleEventManager *appleEventManager = [NSAppleEventManager sharedAppleEventManager];
[appleEventManager setEventHandler:self
                       andSelector:@selector(handleEvent:withReplyEvent:)
                     forEventClass:kCoreEventClass
                        andEventID:kAEOpenDocuments];

这是方法

(void)handleEvent:(NSAppleEventDescriptor *)event withReplyEvent: (NSAppleEventDescriptor *)replyEvent
{
请记住，

您必须将 Cocoa 代码导出到另一个文件（最好是 .mm），但您仍然可以在该文件中使用 C++/Qt 代码，没有任何问题。

I had same problem. I'm not sure but i think it did work. But take a look at it from different side. Why keep legacy code? Carbon API is not 64 bit. Migration of this code shouldn't be hard (check NSAppleEventManager).

This is how you register:

NSAppleEventManager *appleEventManager = [NSAppleEventManager sharedAppleEventManager];
[appleEventManager setEventHandler:self
                       andSelector:@selector(handleEvent:withReplyEvent:)
                     forEventClass:kCoreEventClass
                        andEventID:kAEOpenDocuments];

And this is method

(void)handleEvent:(NSAppleEventDescriptor *)event withReplyEvent: (NSAppleEventDescriptor *)replyEvent
{
}

Remember that you will have to export Cocoa code to another file (best would be .mm), but still you can use your C++/Qt code inside of that file without any problem.
