Constructor & Destructor Documentation

QY2Styler()

QY2Styler::QY2Styler ( QObject * parent, const QString & defaultStyleSheet = "", const QString & alternateStyleSheet = "" )

protected

Constructor. Use the static styler() function instead to return the singleton for this class.

Member Function Documentation

allStyleSheets()

QStringList QY2Styler::allStyleSheets

(

)

Return a sorted list of all style sheets in the theme directory.

alternateStyleSheet()

QString QY2Styler::alternateStyleSheet ( ) const

inline

Return the name of the alternate theme.

buildStyleSheet() [1/2]

QString QY2Styler::buildStyleSheet ( const QString & content )

protected

Build a stylesheet from a string.

buildStyleSheet() [2/2]

QString QY2Styler::buildStyleSheet ( const QString & content, QStringList & alreadyImportedFilenames_ret )

protected

Build a stylesheet from a string.

alreadyImportedFilenames_ret is a return parameter that will contain the names of files that have already been imported.

buildStyleSheetFromFile()

QString QY2Styler::buildStyleSheetFromFile ( const QString & filename, QStringList & alreadyImportedFilenames_ret )

protected

Build a stylesheet from a file.

alreadyImportedFilenames_ret is a return parameter that will contain the names of files that have already been imported.

currentStyleSheet()

QString QY2Styler::currentStyleSheet ( ) const

inline

Return the name of the last loaded style sheet.

defaultStyleSheet()

QString QY2Styler::defaultStyleSheet ( ) const

inline

Return the name of the default theme.

loadAlternateStyleSheet()

bool QY2Styler::loadAlternateStyleSheet

(

)

Loads the alternate stylesheet

The alternate stylesheet is determined by the environment variable Y2ALTSTYLE. If this variable is not set, the HIGH_COLOR_STYLE_SHEET style sheet will be used.

Returns

true if the stylesheet was loaded; false otherwise.

loadDefaultStyleSheet()

bool QY2Styler::loadDefaultStyleSheet

(

)

Loads the default stylesheet.

The default stylesheet is determined by the environment variable Y2STYLE. If this variable is not set, the DEFAULT_STYLE_SHEET style sheet will be used.

Returns

true if the stylesheet was loaded; false otherwise.

loadStyleSheet()

bool QY2Styler::loadStyleSheet

(

const QString &

file

)

Loads and apply a style sheet from a file.

Parameters

file	Filename. It should live in the themeDir() directory.

Returns

true if the file was found (and applied); false otherwise.

void QY2Styler::processUrls ( QString & text )

protected

Search and replace some self-defined macros in the style sheet. Among other things, expands the file name inside url( filename.png ) in the style sheet with the full path.

registerChildWidget()

void QY2Styler::registerChildWidget	(	QWidget *	parent,
		QWidget *	widget )

Registers a child widget.

Parameters

parent	Parent widget.
widget	Widget to register.

setAlternateStyleSheet()

void QY2Styler::setAlternateStyleSheet

(

const QString &

styleSheet

)

Set the name of the style sheet for the alternate theme. If the style sheet does not exists, it won't be changed.

Parameters

styleSheet
