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 = "ntqevent.html#Type-enum" > ChildRemoved< / a > event is sent immediately, but a < a href = "ntqevent.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 = "ntqevent.html#Type-enum" > ChildInserted< / a > event may be suppressed, but the < a href = "ntqevent.html#Type-enum" > ChildRemoved< / a > event will always be sent. In this case there will be
a < a href = "ntqevent.html#Type-enum" > ChildRemoved< / a > event without a corresponding < a href = "ntqevent.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 = "ntqevent.html#Type-enum" > Type< / a > type, < a href = "tqobject.html" > TQObject< / a > * 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 = "ntqevent.html#Type-enum" > TQEvent::ChildInserted< / a > or
< a href = "ntqevent.html#Type-enum" > TQEvent::ChildRemoved< / a > .
< h3 class = fn > < a href = "tqobject.html" > TQObject< / a > * < 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.
