[править] Qt 3 Support Members for QPixmap
The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.

[править] Описание типов членов
[править] enum QPixmap::ColorMode
This enum type defines the color modes that exist for converting QImage objects to QPixmap. It is provided here for compatibility with earlier versions of Qt.
Use Qt::ImageConversionFlags instead.
Constant | Value | Description |
---|---|---|
QPixmap::Auto | 0 | Select Color or Mono on a case-by-case basis. |
QPixmap::Color | 1 | Always create colored pixmaps. |
QPixmap::Mono | 2 | Always create bitmaps. |
[править] Описание функций-членов
[править] QPixmap::QPixmap ( const QString & fileName, const char * format, ColorMode mode )
Use the constructor that takes a Qt::ImageConversionFlag instead.
[править] QPixmap::QPixmap ( const QImage & image )
Constructs a pixmap from the QImage image.
Use the static fromImage() function instead.
[править] bool QPixmap::convertFromImage ( const QImage & image, ColorMode mode )
Use the static fromImage() function instead.
[править] bool QPixmap::convertFromImage ( const QImage & image, Qt::ImageConversionFlags flags = Qt::AutoColor )
This is an overloaded member function, provided for convenience.
Use the static fromImage() function instead.
[править] QImage QPixmap::convertToImage () const
Use the toImage() function instead.
[править] bool QPixmap::load ( const QString & fileName, const char * format, ColorMode mode )
This is an overloaded member function, provided for convenience.
Use the load() function that takes a Qt::ImageConversionFlag instead.
[править] bool QPixmap::loadFromData ( const uchar * buf, uint len, const char * format, ColorMode mode )
This is an overloaded member function, provided for convenience.
Use the loadFromData() function that takes a Qt::ImageConversionFlag instead.
[править] void QPixmap::resize ( int width, int height )
Use the QPixmap constructor that takes two ints (width and height) instead.
For example, if you have code like
pixmap.resize(10, 20);
you can rewrite it as
pixmap = QPixmap(10, 20);
[править] void QPixmap::resize ( const QSize & size )
This is an overloaded member function, provided for convenience.
Use the QPixmap constructor that takes a QSize (size) instead.
For example, if you have code like
pixmap.resize(size);
you can rewrite it as
pixmap = QPixmap(size);
[править] bool QPixmap::selfMask () const
Returns whether the pixmap is its own mask or not.
This function is no longer relevant since the concept of self masking doesn't exists anymore.
[править] QPixmap QPixmap::xForm ( const QMatrix & matrix ) const
Use transformed() instead.
[править] QPixmap::operator QImage () const
Returns the pixmap as a QImage.
Use the toImage() function instead.
[править] QPixmap & QPixmap::operator= ( const QImage & image )
This is an overloaded member function, provided for convenience.
Converts the given image to a pixmap that is assigned to this pixmap.
Use the static fromImage() function instead.
