<hr><a name="details"></a><h2>Detailed Description</h2>
The TQChildEvent class contains event parameters for child object
events.
<p>
<p> Child events are sent to objects when children are inserted or
removed.
<p> A <a href="tqevent.html#Type-enum">ChildRemoved</a> event is sent immediately, but a <a href="tqevent.html#Type-enum">ChildInserted</a> event is <em>posted</em> (with <a href="ntqapplication.html#postEvent">TQApplication::postEvent</a>()).
<p> Note that if a child is removed immediately after it is inserted,
the <a href="tqevent.html#Type-enum">ChildInserted</a> event may be suppressed, but the <a href="tqevent.html#Type-enum">ChildRemoved</a> event will always be sent. In this case there will be
a <a href="tqevent.html#Type-enum">ChildRemoved</a> event without a corresponding <a href="tqevent.html#Type-enum">ChildInserted</a>
event.
<p> The handler for these events is <a href="tqobject.html#childEvent">TQObject::childEvent</a>().
<p>See also <a href="events.html">Event Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQChildEvent"></a>TQChildEvent::TQChildEvent ( <a href="tqevent.html#Type-enum">Type</a>&nbsp;type, <a href="tqobject.html">TQObject</a>&nbsp;*&nbsp;child )
</h3>
<p> Constructs a child event object. The <em>child</em> is the object that
is to be removed or inserted.
<p> The <em>type</em> parameter must be either <a href="tqevent.html#Type-enum">TQEvent::ChildInserted</a> or
<a href="tqevent.html#Type-enum">TQEvent::ChildRemoved</a>.
<h3 class=fn><a href="tqobject.html">TQObject</a>&nbsp;* <a name="child"></a>TQChildEvent::child () const
</h3>
<p> Returns the child widget that was inserted or removed.
<h3 class=fn>bool <a name="inserted"></a>TQChildEvent::inserted () const
</h3>
<p> Returns TRUE if the widget received a new child; otherwise returns
FALSE.
<h3 class=fn>bool <a name="removed"></a>TQChildEvent::removed () const
</h3>
<p> Returns TRUE if the object lost a child; otherwise returns FALSE.
