|
|---|
| 49 |
|
|---|
| 50 | The QChildEvent class contains event parameters for child object
|
|---|
| 51 | events.
|
|---|
| 52 | <p>
|
|---|
| 53 | <p> Child events are sent to objects when children are inserted or
|
|---|
| 54 | removed.
|
|---|
| 55 | <p> A <a href="qevent.html#Type-enum">ChildRemoved</a> event is sent immediately, but a <a href="qevent.html#Type-enum">ChildInserted</a> event is <em>posted</em> (with <a href="qapplication.html#postEvent">QApplication::postEvent</a>()).
|
|---|
| 56 | <p> Note that if a child is removed immediately after it is inserted,
|
|---|
| 57 | the <a href="qevent.html#Type-enum">ChildInserted</a> event may be suppressed, but the <a href="qevent.html#Type-enum">ChildRemoved</a> event will always be sent. In this case there will be
|
|---|
| 58 | a <a href="qevent.html#Type-enum">ChildRemoved</a> event without a corresponding <a href="qevent.html#Type-enum">ChildInserted</a>
|
|---|
| 59 | event.
|
|---|
| 60 | <p> The handler for these events is <a href="qobject.html#childEvent">QObject::childEvent</a>().
|
|---|
| 61 | <p>See also <a href="events.html">Event Classes</a>.
