.SH "Constructor & Destructor Documentation"
.PP 
.SS "QwtDoubleSize::QwtDoubleSize ()"
.PP
Constructs a size with a width and height of 0.0. 
.SS "QwtDoubleSize::QwtDoubleSize (double width, double height)"
.PP
Constructs a size with a width w and height h. 
.SS "QwtDoubleSize::QwtDoubleSize (const QSize &)"
.PP
Copy constructor. 
.SH "Member Function Documentation"
.PP 
.SS "\fBQwtDoubleSize\fP QwtDoubleSize::boundedTo (const \fBQwtDoubleSize\fP & other) const"
.PP
Returns a size with the minimum width and height of this size and other. 
.SS "\fBQwtDoubleSize\fP QwtDoubleSize::expandedTo (const \fBQwtDoubleSize\fP & other) const"
.PP
Returns a size with the maximum width and height of this size and other. 
.SS "double QwtDoubleSize::height () const"
.PP
Returns the height. 
.SS "bool QwtDoubleSize::isEmpty () const"
.PP
Returns TRUE if the width is <= 0 or the height is <= 0, otherwise FALSE. 
.SS "bool QwtDoubleSize::isNull () const"
.PP
Returns TRUE if the width is 0 and the height is 0; otherwise returns FALSE. 
.SS "const  \fBQwtDoubleSize\fP QwtDoubleSize::operator * (double) const"
.PP
Returns the size formed by multiplying both components by c. 
.SS "bool QwtDoubleSize::operator!= (const \fBQwtDoubleSize\fP &) const"
.PP
Returns TRUE if the size is not equal to other; otherwise returns FALSE. 
.SS "const  \fBQwtDoubleSize\fP QwtDoubleSize::operator+ (const \fBQwtDoubleSize\fP & other) const"
.PP
Returns the size formed by adding both components by the components of other. Each component is added separately. 
.SS "\fBQwtDoubleSize\fP & QwtDoubleSize::operator+= (const \fBQwtDoubleSize\fP &)"
.PP
Adds size other to this size and returns a reference to this size. 
.SS "const  \fBQwtDoubleSize\fP QwtDoubleSize::operator- (const \fBQwtDoubleSize\fP & other) const"
.PP
Returns the size formed by subtracting both components by the components of other. Each component is subtracted separately. 
.SS "const  \fBQwtDoubleSize\fP QwtDoubleSize::operator- () const"
.PP
Returns the size formed by changing the sign of both components, equivalent to QwtDoubleSize(-width(), -height()); 
.SS "\fBQwtDoubleSize\fP & QwtDoubleSize::operator-= (const \fBQwtDoubleSize\fP &)"
.PP
Subtracts size other from this size and returns a reference to this size. 
.SS "const  \fBQwtDoubleSize\fP QwtDoubleSize::operator/ (double) const"
.PP
Returns the size formed by dividing both components by c. 
.SS "bool QwtDoubleSize::operator== (const \fBQwtDoubleSize\fP &) const"
.PP
Returns TRUE if the size is equal to other; otherwise returns FALSE. 
.SS "double & QwtDoubleSize::rheight ()"
.PP
Returns a reference to the height. 
.SS "double & QwtDoubleSize::rwidth ()"
.PP
Returns a reference to the width. 
.SS "void QwtDoubleSize::setHeight (double h)"
.PP
Sets the height to height. 
.SS "void QwtDoubleSize::setWidth (double w)"
.PP
Sets the width to width. 
.SS "void QwtDoubleSize::transpose ()"
.PP
Swaps the values of width and height. 
.SS "double QwtDoubleSize::width () const"
.PP
Returns the width.
