Member Function Documentation

int QImage::serialNumber () const

Returns a number that identifies the contents of this QImage object. Distinct QImage objects can only have the same serial number if they refer to the same contents (but they don't have to).

Use cacheKey() instead.

Warning: The serial number doesn't necessarily change when the image is altered. This means that it may be dangerous to use it as a cache key.

See also operator==().

void QImage::setText ( const char * key, const char * language, const QString & text )

This is an overloaded member function, provided for convenience.

Sets the image text to the given text and associate it with the given key. The text is recorded in the specified language, or in a default language if language is 0.

Use setText() instead.

The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.

QString QImage::text ( const char * key, const char * language = 0 ) const

This is an overloaded member function, provided for convenience.

Returns the text recorded for the given key in the given language, or in a default language if language is 0.

Use text() instead.

The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.

QString QImage::text ( const QImageTextKeyLang & keywordAndLanguage ) const

This is an overloaded member function, provided for convenience.

Returns the text recorded for the given keywordAndLanguage.

Use text() instead.

The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.

QStringList QImage::textLanguages () const

Returns the language identifiers for which some texts are recorded. Note that if you want to iterate over the list, you should iterate over a copy.

The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.

QList<QImageTextKeyLang> QImage::textList () const

Returns a list of QImageTextKeyLang objects that enumerate all the texts key/language pairs set for this image.

Use textKeys() instead.

The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.
