Global Mouse Hooking for Mac OS

[Himanshu Rohilla]

Hello everyone,

I want the mouse events like Mouse Move, Mouse Up, Mouse Down globally means also find out these events outside the application on the Mac OS. I have some code which execute perfect with the Cocoa Application. But, when i use that code in Qt Application, It does not work. THis is my code.

@#include <QDebug>

#include <CoreFoundation/CoreFoundation.h>
#include <ApplicationServices/ApplicationServices.h>

extern CGEventRef handleCGEvent(CGEventTapProxy proxy, CGEventType type, CGEventRef eventRef, void *refcon);

CGEventRef handleCGEvent(CGEventTapProxy proxy, CGEventType type, CGEventRef eventRef, void *refcon)
{
if (type == kCGEventLeftMouseDown )
{
qDebug() << "kCGEventLeftMouseDown";
}
else if(type == kCGEventLeftMouseUp)
{
qDebug() << "kCGEventLeftMouseUp";
}
else if(type == kCGEventMouseMoved)
{
qDebug() << "kCGEventMouseMoved";
}

return eventRef;

}

CMouseEvent::CMouseEvent(QObject *parent) :
QObject(parent)
{
CFMachPortRef eventTap = CGEventTapCreate(kCGHIDEventTap, kCGHeadInsertEventTap, kCGEventTapOptionDefault, kCGEventMaskForAllEvents, handleCGEvent, NULL);
CFRunLoopSourceRef runLoopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, eventTap, 0);
CFRunLoopAddSource(CFRunLoopGetMain(), runLoopSource, kCFRunLoopCommonModes);
CGEventTapEnable(eventTap, true);
}

This is a class which is used for mouse events. I am creating an object of this class in main() function. My application is console application.

When i run this code, it stuck in the code. I don't know where it stuck. Mouse only move but unable to click anywhere.

Thanks in advance....
