QMetaProperty(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QMetaProperty(3qt) 💖

ok so bestie, welcome to the QMetaProperty page from the Qt 3 manual, section 3qt. this one's short and sweet and honestly kind of iconic for what it does. let's get into it 🫶

✨ NAME ✨

QMetaProperty — it's the little container that stores meta data about a property. that's the whole job. it holds the receipts 📝

🌸 SYNOPSIS 🌸

#include <qmetaobject.h>

👑 Public Members 👑

const char * type () const
const char * name () const
bool writable () const
bool isSetType () const
bool isEnumType () const
QStrList enumKeys () const
int keyToValue ( const char * key ) const
const char * valueToKey ( int value ) const
int keysToValue ( const QStrList & keys ) const
QStrList valueToKeys ( int value ) const
bool designable ( QObject * o = 0 ) const
bool scriptable ( QObject * o = 0 ) const
bool stored ( QObject * o = 0 ) const
bool reset ( QObject * o ) const

🦋 DESCRIPTION 🦋

so like, the QMetaProperty class stores meta data about a property. that's it, that's the vibe. 💅

the meta data it's holding includes type(), name(), and whether a property is writable(), designable() and stored(). all the little facts about a property, living in one place, slaying ✨

the functions isSetType(), isEnumType() and enumKeys() give you even more info about a property's type. and the conversion girlies — keyToValue(), valueToKey(), keysToValue() and valueToKeys() — let you convert between the integer representation of an enumeration or set value and its literal representation. so you can go back and forth, no cap 🔁

heads up bestie: actual property values are set and received through QObject's set and get functions. peep QObject::setProperty() and QObject::property() for the deets.

and you receive meta property data through an object's meta object. see QMetaObject::property() and QMetaObject::propertyNames() for the deets on that.

💜 MEMBER FUNCTION DOCUMENTATION 💜

bool QMetaProperty::designable ( QObject * o = 0 ) const

returns TRUE if the property is designable for object o; otherwise returns FALSE.

if no object o is given, the function returns a static approximation. (iykyk — it's just an estimate at that point 🙈)

QStrList QMetaProperty::enumKeys () const

returns the possible enumeration keys if this property is an enumeration type (or a set type). all the options, laid out 🎀

See also: isEnumType().

bool QMetaProperty::isEnumType () const

returns TRUE if the property's type is an enumeration value; otherwise returns FALSE.

See also: isSetType() and enumKeys().

bool QMetaProperty::isSetType () const

returns TRUE if the property's type is an enumeration value that is used as set, i.e. if the enumeration values can be OR-ed together; otherwise returns FALSE. a set type is implicitly also an enum type. like, it's giving enum but with extra ✨

See also: isEnumType() and enumKeys().

int QMetaProperty::keyToValue ( const char * key ) const

converts the enumeration key key to its integer value. 🔢

for set types, use keysToValue() instead, okay?

See also: valueToKey(), isSetType(), and keysToValue().

int QMetaProperty::keysToValue ( const QStrList & keys ) const

converts the list of keys keys to their combined (OR-ed) integer value. mashing them all together into one number 💥

See also: isSetType() and valueToKey().

const char * QMetaProperty::name () const

returns the name of the property. literally just the name. iconic, minimal, we love her 💅

bool QMetaProperty::reset ( QObject * o ) const

tries to reset the property for object o with a reset method. on success, returns TRUE; otherwise returns FALSE.

reset methods are optional, and usually only a few properties support them. so don't come for her if she says no 🙈

bool QMetaProperty::scriptable ( QObject * o = 0 ) const

returns TRUE if the property is scriptable for object o; otherwise returns FALSE.

if no object o is given, the function returns a static approximation.

bool QMetaProperty::stored ( QObject * o = 0 ) const

returns TRUE if the property shall be stored for object o; otherwise returns FALSE.

if no object o is given, the function returns a static approximation.

const char * QMetaProperty::type () const

returns the type of the property. yes bestie, that's the whole paragraph. short queen 👑

const char * QMetaProperty::valueToKey ( int value ) const

converts the enumeration value value to its literal key. 🔑

for set types, use valueToKeys().

See also: isSetType() and valueToKeys().

QStrList QMetaProperty::valueToKeys ( int value ) const

converts the set value value to a list of keys.

See also: isSetType() and valueToKey().

bool QMetaProperty::writable () const

returns TRUE if the property is writable; otherwise returns FALSE. can you touch it or not, that's the question ✍️
