qt for mac

如何在mac上识别docker栏的"退出"?

废话不多说直接上代码

void dockerQuitHandler(id self,SEL _cmd,...)
{
    Q_UNUSED(self)
    Q_UNUSED(_cmd)
    //这里写要在退出的时候 *** 作 *** 作
    cout<<"docker quit";
}
Class cls = objc_getClass("NSApplication");
objc_object *app=pobjc_msgSend((objc_object*)cls,sel_registerName("sharedApplication"));
if(app != NULL) {
    SEL shouldterminate = sel_registerName("applicationShouldTerminate:");
	objc_object* delegate = objc_msgSend(app, sel_registerName("delegate"));
    Class delClass = (Class)objc_msgSend(delegate,  sel_registerName("class"));
    if (class_getInstanceMethod(delc, shouldterminate)) {
    	if (class_replaceMethod(delc, shouldterminate, (IMP)dockerQuitHandler, "L@:@"))
    		cout << "Registered dock quit handler success";
    	else
        	cout << "Failed";
    }
}

这里https://developer.apple.com/documentation/appkit/nsapplication/有详细的接口说明，具体需求看具体的函数。
