Detailed Description

Member Function Documentation

◆ colorScheme()

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

Reimplemented from QPlatformTheme.

Definition at line 695 of file qkdetheme.cpp.

◆ createKdeTheme()

QPlatformTheme * QKdeTheme::createKdeTheme ( )
static

Definition at line 763 of file qkdetheme.cpp.

◆ fileIcon()

QIcon QKdeTheme::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 647 of file qkdetheme.cpp.

◆ font()

const QFont * QKdeTheme::font ( Font type) const
overridevirtual

Reimplemented from QGenericUnixTheme.

Definition at line 757 of file qkdetheme.cpp.

◆ palette()

const QPalette * QKdeTheme::palette ( 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 744 of file qkdetheme.cpp.

◆ requestColorScheme()

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

QKdeTheme::requestColorScheme Programmatically request a color scheme If scheme is Dark or Light, scheme is applied to the application, independently from the current KDE theme. If scheme is Unknown, the current KDE theme's color scheme will be applied instead. This is the default behavior.

\reimp

Note
A KDE theme is considered either Dark or Light. When the requested color scheme doesn't match the current KDE theme, a default Dark or Light fusion palette is used instead.

QKdeThemePrivate::hasRequestedColorScheme Check if fusion palette fallback is necessary. This internal helper function returns true, if \list

  • a color scheme has been programmatically requested, and
  • the requested color scheme differs from the current KDE theme's color scheme. \endlist
