[PyKDE] Why are this function not implemented in PyQT

[Benoit DELAGARDE]

QFontMetrics 

QRect boundingRect(int x, int y, int w, int h, int flags, const char
*str, int len = -1, int tabstops = 0, int *tabarray = 0); 

Not yet implemented. 

QSize size(int flags, const char *str, int len = -1, int tabstops = 0,
int *tabarray = 0); 

Not yet implemented. 

I don't understand why this functions are not implemented.
