Returns a size with the minimum width and height of this size and other. Definition at line 181 of file qwt_double_rect.cpp.

References d_height, d_width, and QwtDoubleSize().  

QwtDoubleSize QwtDoubleSize::expandedTo (const QwtDoubleSize & other) const

Returns a size with the maximum width and height of this size and other. Definition at line 167 of file qwt_double_rect.cpp.

Returns the height.

bool QwtDoubleSize::isEmpty () const

Returns TRUE if the width is <= 0 or the height is <= 0, otherwise FALSE. Definition at line 235 of file qwt_double_rect.h.  

bool QwtDoubleSize::isNull () const

Returns TRUE if the width is 0 and the height is 0; otherwise returns FALSE. Definition at line 226 of file qwt_double_rect.h.  

bool QwtDoubleSize::isValid () const

Returns TRUE if the width is equal to or greater than 0 and the height is equal to or greater than 0; otherwise returns FALSE. Definition at line 244 of file qwt_double_rect.h.

const QwtDoubleSize QwtDoubleSize::operator- () const

Returns the size formed by changing the sign of both components, equivalent to QwtDoubleSize(-width(), -height()); Definition at line 209 of file qwt_double_rect.cpp.

References QwtDoubleSize().  

QwtDoubleSize & QwtDoubleSize::operator-= (const QwtDoubleSize &)

Subtracts size other from this size and returns a reference to this size.

Definition at line 263 of file qwt_double_rect.cpp.

References d_height, and d_width.  

const QwtDoubleSize QwtDoubleSize::operator/ (double) const

Returns the size formed by dividing both components by c.

Definition at line 247 of file qwt_double_rect.cpp.
