Detailed Description

A class to split a pixmap into several items.

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( TQSize( 20, 10 ));
 
TQPixmap item( 20, 10 );
item.fill( TQt::white );
TQRect rect = splitter.coordinates( 4 );
if ( !rect.isEmpty() )
    bitBlt( &item, TQPoint(0,0), &somePixmap, rect, CopyROP );

Member Function Documentation

coordinates() [1/2]

TQRect KPixmapSplitter::coordinates

(

const TQChar &

ch

)

Overloaded for convenience.

Returns the item at the position of the given character (when using a latin1 font-pixmap)

Definition at line 91 of file kpixmapsplitter.cpp.

coordinates() [2/2]

TQRect KPixmapSplitter::coordinates

(

int

pos

)

Returns

the coordinates of the item at position pos in the given pixmap.

Definition at line 67 of file kpixmapsplitter.cpp.

itemSize()

TQSize KPixmapSplitter::itemSize ( ) const

inline

Returns

the set size of the items (coordinates) you want to get out of the given pixmap.

Definition at line 83 of file kpixmapsplitter.h.

pixmap()

const TQPixmap& KPixmapSplitter::pixmap ( ) const

inline

Returns

the pixmap that has been set via setPixmap().

Definition at line 70 of file kpixmapsplitter.h.

setHSpacing()

void KPixmapSplitter::setHSpacing

(

int

spacing

)

If there is space between columns in the given pixmap, you have to specify how many pixels there are.

Definition at line 58 of file kpixmapsplitter.cpp.

setItemSize()

void KPixmapSplitter::setItemSize

(

const TQSize &

size

)

Sets the size of the items you want to get out of the given pixmap.

The TQRect of coordinates(int) will have the width and height of exactly this size.

Definition at line 42 of file kpixmapsplitter.cpp.

setPixmap()

void KPixmapSplitter::setPixmap

(

const TQPixmap &

pixmap

)

Sets the pixmap to be split.

Definition at line 36 of file kpixmapsplitter.cpp.

setVSpacing()

void KPixmapSplitter::setVSpacing

(

int

spacing

)

If there is space between rows in the given pixmap, you have to specify how many pixels there are.
