◆ QIOSTheme()

QIOSTheme::QIOSTheme ( )

Definition at line 40 of file qiostheme.mm.

References initializeSystemPalette().

Here is the call graph for this function:

Member Function Documentation

◆ applyTheme()

void QIOSTheme::applyTheme ( UIWindow * window)
static

Definition at line 205 of file qiostheme.mm.

◆ colorScheme()

Qt::ColorScheme QIOSTheme::colorScheme ( ) const
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 160 of file qiostheme.mm.

◆ createIconEngine()

QIconEngine * QIOSTheme::createIconEngine ( const QString & iconName) const
overridevirtual

Factory function for the QIconEngine used by QIcon::fromTheme().

By default this function returns a QIconLoaderEngine, but subclasses can reimplement it to provide their own.

It is especially useful to benefit from some platform specific facilities or optimizations like an inter-process cache in systems mostly built with Qt.

Since
5.1

Reimplemented from QPlatformTheme.

Definition at line 228 of file qiostheme.mm.

◆ createPlatformDialogHelper()

QPlatformDialogHelper * QIOSTheme::createPlatformDialogHelper ( QPlatformTheme::DialogType type) const
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 124 of file qiostheme.mm.

◆ createPlatformMenu()

QPlatformMenu * QIOSTheme::createPlatformMenu ( ) const
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 105 of file qiostheme.mm.

◆ createPlatformMenuItem()

QPlatformMenuItem * QIOSTheme::createPlatformMenuItem ( ) const
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 100 of file qiostheme.mm.

◆ fileIcon()

QIcon QIOSTheme::fileIcon ( const QFileInfo & fileInfo,
QPlatformTheme::IconOptions iconOptions = {} ) const
overridevirtual

Return an icon for fileInfo, observing iconOptions.

This function is queried by QFileIconProvider and similar classes to obtain an icon for a file. If it does not return a non-null icon, fileIconPixmap() is queried for a specific size.

Since
5.8

Reimplemented from QPlatformTheme.

Definition at line 233 of file qiostheme.mm.

◆ font()

const QFont * QIOSTheme::font ( Font type = SystemFont) const
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 221 of file qiostheme.mm.

◆ initializeSystemPalette()

void QIOSTheme::initializeSystemPalette ( )
static

Definition at line 57 of file qiostheme.mm.

Referenced by QIOSTheme().

Here is the caller graph for this function:

◆ palette()

const QPalette * QIOSTheme::palette ( QPlatformTheme::Palette type = SystemPalette) const
overridevirtual

Return a color palette for type type.

When relying on system color palette keep in mind that it is lazily initialized and cached. If it needs to be updated (i.e. due to ColorScheme changes), it's up to the caller to take care of it. See requestColorScheme.

Reimplemented from QPlatformTheme.

Definition at line 92 of file qiostheme.mm.

◆ requestColorScheme()

void QIOSTheme::requestColorScheme ( Qt::ColorScheme scheme)
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 189 of file qiostheme.mm.

◆ themeHint()

QVariant QIOSTheme::themeHint ( ThemeHint hint) const
overridevirtual

Reimplemented from QPlatformTheme.

Definition at line 146 of file qiostheme.mm.

◆ usePlatformNativeDialog()

bool QIOSTheme::usePlatformNativeDialog ( QPlatformTheme::DialogType type) const

Reimplemented from QPlatformTheme.
