You must also provide a function that connects the signal -to an outside object slot. This is how we have implemented -signals in the <a href="qmenudata.html">TQMenuData</a> class, which is not a TQObject. -<p> In general, we recommend inheriting TQObject instead. TQObject -provides much more functionality. -<p> You can set a single <a href="qvariant.html">TQVariant</a> parameter for the signal with -<a href="#setValue">setValue</a>(). -<p> Note that TQObject is a <em>private</em> base class of TQSignal, i.e. you -cannot call any TQObject member functions from a TQSignal object. -<p> Example: -<pre> - #include <<a href="qsignal-h.html">qsignal.h</a>> - - class MyClass - { - public: - MyClass(); - ~MyClass(); - - void doSomething(); - - void connect( <a href="qobject.html">TQObject</a> *receiver, const char *member ); - - private: - TQSignal *sig; - }; - - MyClass::MyClass() - { - sig = new TQSignal; - } - - MyClass::~MyClass() - { - delete sig; - } - - void MyClass::doSomething() - { - // ... does something - sig-><a href="#activate">activate</a>(); // emits the signal - } - - void MyClass::connect( <a href="qobject.html">TQObject</a> *receiver, const char *member ) - { - sig-><a href="#connect">connect</a>( receiver, member ); - } - </pre> - -<p>See also <a href="io.html">Input/Output and Networking</a> and <a href="misc.html">Miscellaneous Classes</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQSignal"></a>TQSignal::TQSignal ( <a href="qobject.html">TQObject</a> * parent = 0, const char * name = 0 ) -</h3> -Constructs a signal object called <em>name</em>, with the parent object -<em>parent</em>.
