QChildEvent(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QChildEvent 💖 — it's giving "your kid just showed up / your kid just left"

okay bestie, welcome to the qchildevent.3qt manual page, the group chat where Qt tells you when a child object gets inserted or removed. it's a whole event class. it's iconic. let's go 🦋

✨ NAME ✨

QChildEvent — the event parameters for child object events. literally just vibes about kids coming and going 💅

🌸 SYNOPSIS 🌸

#include <qevent.h>

Inherits QEvent. yeah she's part of the family tree 🧚

🎀 Public Members 🎀

QChildEvent ( Type type, QObject * child )
QObject * child () const
bool inserted () const
bool removed () const

🌈 DESCRIPTION 🌈

okay so the QChildEvent class holds the event parameters for child object events. that's the whole job. main character energy but make it a struct 🫶

Child events get sent to objects when children are inserted or removed. it's the "new baby alert" / "they moved out" notification system for your object tree.

here's the tea though: a ChildRemoved event is sent immediately, but a ChildInserted event is posted (with QApplication::postEvent()). so one is right now, one is in the mail. not me being asynchronous 😭

⚠️ also important: if a child is removed immediately after it is inserted, the ChildInserted event may be suppressed, but the ChildRemoved event will always be sent. so in that case you get a ChildRemoved event with no corresponding ChildInserted event. the breakup text arrives, the "we're dating" text never does 💀

The handler for these events is QObject::childEvent(). that's where you do your thing.

See also Event Classes.

💅 MEMBER FUNCTION DOCUMENTATION 💅

🌟 QChildEvent::QChildEvent ( Type type, QObject * child )

Constructs a child event object. child is the object that is to be removed or inserted — the little one in question 👑

The type parameter must be either QEvent::ChildInserted or QEvent::ChildRemoved. no third option, bestie, pick one of the two or it's not it.

🌟 QObject * QChildEvent::child () const

Returns the child widget that was inserted or removed. that's your baby right there 🥺

🌟 bool QChildEvent::inserted () const

Returns TRUE if the widget received a new child; otherwise returns FALSE. new addition to the family, slay ✨

🌟 bool QChildEvent::removed () const

Returns TRUE if the object lost a child; otherwise returns FALSE. they left. we're fine. we're totally fine 😭
