If you have a pixmap containing several items (icons), you can use this class to get the coordinates of each item.
For example, if you have a pixmap with 25 items and you want to get the 4th item as a pixmap (every item being 20x10 pixels):
KPixmapSplitter splitter; splitter.setPixmap( somePixmap ); splitter.setItemSize( QSize( 20, 10 )); QPixmap item( 20, 10 ); item.fill( Qt::white ); QRect rect = splitter.coordinates( 4 ); if ( !rect.isEmpty() ) bitBlt( &item, QPoint(0,0), &somePixmap, rect, CopyROP ); @short A class to split a pixmap into several items. @author Carsten Pfeiffer <pfeiffer@kde.org> |

Constructor, does nothing but initializing some default-values.
|
void |
Set the pixmap to be splitted.
const QPixmap& |
[const]
Returns: the pixmap that has been set via setPixmap().
void |
Set the size of the items you want to get out of the given pixmap.
The QRect of coordinate will have the width and height of exactly
this size.
QSize |
[const]
Returns: the set size of the items (coordinates) you want to get out of the given pixmap.
void |
If there is space between rows in the given pixmap, you have to specify how many pixels there are.
void |
If there is space between columns in the given pixmap, you have to specify how many pixels there are.
QRect |
Returns: the coordinates of the item at position pos in the given pixmap.
QRect |
Overloaded for convenience. Returns the item at the position of the given character (when using a latin1 font-pixmap)
