+    \class TQSignal qsignal.h
+    \brief The TQSignal class can be used to send signals for classes
+    that don't inherit TQObject.
+
+    \ingroup io
+    \ingroup misc
+
+    If you want to send signals from a class that does not inherit
+    TQObject, you can create an internal TQSignal object to emit the
+    signal. You must also provide a function that connects the signal
+    to an outside object slot.  This is how we have implemented
+    signals in the TQMenuData class, which is not a TQObject.
+
+    In general, we recommend inheriting TQObject instead. TQObject
+    provides much more functionality.
+
+    You can set a single TQVariant parameter for the signal with
+    setValue().
+
+    Note that TQObject is a \e private base class of TQSignal, i.e. you
+    cannot call any TQObject member functions from a TQSignal object.
+
+    Example:
+    \code
+	#include <qsignal.h>
+
+	class MyClass
+	{
+	public:
+	    MyClass();
+	    ~MyClass();
+
+	    void doSomething();
+
+	    void connect( TQObject *receiver, const char *member );
+
+	private:
+	    TQSignal *sig;
+	};
+
+	MyClass::MyClass()
+	{
+	    sig = new TQSignal;
+	}
+
+	MyClass::~MyClass()
+	{
+	    delete sig;
+	}
+
+	void MyClass::doSomething()
+	{
+	    // ... does something
+	    sig->activate(); // emits the signal
+	}
+
+	void MyClass::connect( TQObject *receiver, const char *member )
+	{
+	    sig->connect( receiver, member );
+	}
