The following class members are part of the Qt compatibility layer. We advise against using them in new code.
Public Functions
Member Function Documentation
QPixmap QPixmap::alphaChannel() const
See also setAlphaChannel().
int QPixmap::serialNumber() const
Returns a number that identifies the contents of this QPixmap object. Distinct QPixmap 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 pixmap is altered. This means that it may be dangerous to use it as a cache key. For caching pixmaps, we recommend using the QPixmapCache class whenever possible.
void QPixmap::setAlphaChannel(const QPixmap &)
See also alphaChannel().
