Member Function Documentation

QPixmap * QPixmapCache::find ( const QString & key )   [static]

This is an overloaded member function, provided for convenience.

Returns the pixmap associated with the key in the cache, or null if there is no such pixmap.

Warning: If valid, you should copy the pixmap immediately (this is fast). Subsequent insertions into the cache could cause the pointer to become invalid. For this reason, we recommend you use find(const QString&, QPixmap&) instead.

Example:

    QPixmap* pp;
    QPixmap p;
    if ((pp=QPixmapCache::find("my_big_image", pm))) {
        p = *pp;
    } else {
        p.load("bigimage.png");
        QPixmapCache::insert("my_big_image", new QPixmap(p));
    }
    painter->drawPixmap(0, 0, p);
