Member Function Documentation

QwAbsSpriteFieldView::QwAbsSpriteFieldView ( QwSpriteField * v=0 )

Construct a QwAbsSpriteFieldView which views the given QwSpriteField.

void QwAbsSpriteFieldView::beginPainter ( QPainter & ) [virtual]

Called to initialize the QPainter - normally calls QPainter::begin().

void QwAbsSpriteFieldView::flush ( const QRect & area ) [virtual]

Called just before the painter is ended.

bool QwAbsSpriteFieldView::preferDoubleBuffering () const [virtual]

Return TRUE if double-buffering is best for this class of widget. If any view viewing an area prefers double-buffering, that area will be double buffered for all views.

void QwAbsSpriteFieldView::view ( QwSpriteField * v )

Change the QwSpriteField which the QwSpriteFieldView is viewing.

QRect QwAbsSpriteFieldView::viewArea () const [virtual]

viewArea returns the area of `viewing' which this QwAbsSpriteFieldView is viewing. The tighter this rectangle can be defined, the more efficient QwSpriteField::update will be.

Return zero-width area if nothing viewed.
