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 * (double) const

Returns the size formed by multiplying both components by c.

bool QwtDoubleSize::operator!= (const QwtDoubleSize &) const

Returns TRUE if the size is not equal to other; otherwise returns FALSE.

const QwtDoubleSize QwtDoubleSize::operator+ (const QwtDoubleSize & other) const

Returns the size formed by adding both components by the components of other. Each component is added separately. Definition at line 219 of file qwt_double_rect.cpp.

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

Adds size other to this size and returns a reference to this size.

References d_height, and d_width.

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

Returns the size formed by subtracting both components by the components of other. Each component is subtracted separately. Definition at line 231 of file qwt_double_rect.cpp.

References d_height, d_width, and QwtDoubleSize().

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.
