The minimum value of QCOORD is QCOORD_MIN (-2147483648) and the maximum value is QCOORD_MAX (2147483647). +.PP +The size can be set in the constructor and changed with setWidth() and setHeight(), or using operator+=(), operator-=(), operator*=() and operator/=(), etc. You can swap the width and height with transpose(). You can get a size which holds the maximum height and width of two sizes using expandedTo(), and the minimum height and width of two sizes using boundedTo(). +.PP +See also QPoint, QRect, Graphics Classes, and Image Processing Classes. +.SS "Member Type Documentation" +.SH "QSize::ScaleMode" +This enum type defines the different ways of scaling a size. +.PP +<center> +.ce 1 +.B "[Image Omitted]" +.PP +</center> +.TP +\fCQSize::ScaleFree\fR - The size is scaled freely.
