Detailed Description

Provides emoji flags as icons This is a special icon engine that internally paints flags using emoji fonts.

It provides access to country and region flags from the system emoji font.

auto l = new QLabel;
l->setMinimumSize(512, 512);
l->setPixmap(QIcon(new KCountryFlagEmojiIconEngine("AT")).pixmap(512, 512));

Since

6.0

Constructor & Destructor Documentation

KCountryFlagEmojiIconEngine()

KCountryFlagEmojiIconEngine::KCountryFlagEmojiIconEngine ( const QString & regionOrCountry )

explicit

Construct a new KCountryFlagEmojiIconEngine object Please note that regional flag support can be spotty in emoji fonts.

Parameters

regionOrCountry

either a ISO 3166-1 alpha-2 country code or a ISO 3166-2 region code (e.g. AT for Austria or GB-SCT for Scotland)

Definition at line 86 of file kcountryflagemojiiconengine.cpp.

Member Function Documentation

clone()

QIconEngine * KCountryFlagEmojiIconEngine::clone ( ) const

overridevirtual

Implements QIconEngine.

Definition at line 93 of file kcountryflagemojiiconengine.cpp.

isNull()

bool KCountryFlagEmojiIconEngine::isNull ( )

overridevirtual

Check whether the internal emoji unicode sequence is null This does not necessarily mean that the pixmap output will be a valid flag - that entirely depends on the system's precise font configuration.

Returns

true when the construction of the emoji string failed

false when the construction of the emoji string succeeded

Reimplemented from QIconEngine.

key()

QString KCountryFlagEmojiIconEngine::key ( ) const

overridevirtual

Reimplemented from QIconEngine.

Definition at line 98 of file kcountryflagemojiiconengine.cpp.

paint()

void KCountryFlagEmojiIconEngine::paint ( QPainter * painter, const QRect & rect, QIcon::Mode mode, QIcon::State state )

overridevirtual

Implements QIconEngine.

Definition at line 103 of file kcountryflagemojiiconengine.cpp.

pixmap()

QPixmap KCountryFlagEmojiIconEngine::pixmap ( const QSize & size, QIcon::Mode mode, QIcon::State state )

overridevirtual

Reimplemented from QIconEngine.

Definition at line 139 of file kcountryflagemojiiconengine.cpp.

scaledPixmap()

QPixmap KCountryFlagEmojiIconEngine::scaledPixmap ( const QSize & size, QIcon::Mode mode, QIcon::State state, qreal scale )

overridevirtual

Reimplemented from QIconEngine.

Definition at line 144 of file kcountryflagemojiiconengine.cpp.

setGlobalDefaultFont()

void KCountryFlagEmojiIconEngine::setGlobalDefaultFont ( const QFont & font )

static

Set the Global Default Font object This is primarily useful for platform themes that wish to force a specific font being used.

By default the "emoji" font family will be used. Forcing a specific font and making sure it is available as runtime requirement is the most reliable way to ensure that flag support is working regardless of system configuration.

Parameters

font	the default font to use
