Mutexes and deadlocks

After asking a question about mutexes here, I was warned about deadlocks.

Would the example I put together below be a reasonable way to avoid deadlocks?

class Foo
{
public:
    Foo();

    void Thread();

    int GetWidgetProperty();
    int GetGadgetProperty();

private:

    Widget widget_;
    Gadget gadget_;

    VDK::MutexID widgetLock;
    VDK::MutexID gadgetLock;
};


Foo::Foo()
    : widget_(42)
    , gadget_(widget_)
{
    widgetLock = VDK::CreateMutex();
    gadgetLock = VDK::CreateMutex();
}

void Foo::Thread()
{
    while(1)
    {
        VDK::AcquireMutex(widgetLock);
        // Use widget
        VDK::ReleaseMutex(widgetLock);

        VDK::AcquireMutex(widgetLock);
        VDK::AcquireMutex(gadgetLock);
        // use gadget
        VDK::ReleaseMutex(widgetLock);
        VDK::ReleaseMutex(gadgetLock);
    }
}

int Foo::GetWidgetProperty()
{
    VDK::AcquireMutex(widgetLock);
    return widget_.GetProp();
    VDK::ReleaseMutex(widgetLock);
}

int Foo::GetGadgetProperty()
{
    VDK::AcquireMutex(widgetLock);
    VDK::AcquireMutex(gadgetLock);
    return gadget.GetProp();
    VDK::ReleaseMutex(widgetLock);
    VDK::ReleaseMutex(gadgetLock);  
}

Since the call GetGadgetProperty could result in using the widget, I'm guessing we also need to protect our self with a lock here. My question is, am I requiring and releasing them in the right order?
