DESCRIPTION
An array of QCanvasPixmap to have multiple frames for
animation.
This allows sprite objects to have multiple frames for
animation.
QCanvasPixmaps for sprite objects are collected into
QCanvasPixmapArrays, which are the set of images a sprite
will use, indexed by the sprite's frame. This allows
sprites to simply have animated forms.
MEMBER FUNCTION DOCUMENTATIONQCanvasPixmapArray::QCanvasPixmapArray ()
Constructs a null array. You should call readPixmaps()
before using it further.
QCanvasPixmapArray::QCanvasPixmapArray ( QList<;QPixmap> list,
QList<QPoint> hotspots )
Constructs a QCanvasPixmapArray from QPixmaps.
QCanvasPixmapArray::QCanvasPixmapArray ( const QString &
datafilenamepattern, int fc=0 )
Constructs a QCanvasPixmapArray from files. See
readPixmaps() for details.
QCanvasPixmapArray::~QCanvasPixmapArray ()
Destructs the pixmap array.
uint QCanvasPixmapArray::count () const
Returns the length of the array.

QCanvasPixmapArray(3qt)QCanvasPixmapArray(3qt)QCanvasPixmap* QCanvasPixmapArray::image ( int i ) const
Returns the i-th pixmap in the array.
int QCanvasPixmapArray::operator! ()
Constructor failure check.
bool QCanvasPixmapArray::readCollisionMasks ( const QString &
fname )
When testing sprite collision detection the default is to
use the image mask of the sprite. By using
readCollisionMasks(), an alternate mask can be used. The
images must be 1-bit deep.
bool QCanvasPixmapArray::readPixmaps ( const QString &
datafilenamepattern, int fc=0 )
Sets the array to fc pixmaps, read from files.
If fc is not 0, the filenames should contain a "%1",
strings such as "foo%1.png". The actual filenames are
formed by replacing the %1 with each integer from 0 to
fc-1, with leading zeroes sufficient for 4 digits. eg.
foo0000.png, foo0001.png, foo0002.png, etc.
void QCanvasPixmapArray::setImage ( int i, QCanvasPixmap * p )
Replaces the i-th pixmap by p. Note that p becomes owned
by the array - it will be deleted later.
If i is more than count()-1, the array is extended to make
room.
