Detailed Description

The PySide.QtCore.QSize class defines the size of a two-dimensional object using integer point precision.

A size is specified by a PySide.QtCore.QSize.width() and a PySide.QtCore.QSize.height() . It can be set in the constructor and changed using the PySide.QtCore.QSize.setWidth() , PySide.QtCore.QSize.setHeight() , or PySide.QtCore.QSize.scale() functions, or using arithmetic operators. A size can also be manipulated directly by retrieving references to the width and height using the PySide.QtCore.QSize.rwidth() and PySide.QtCore.QSize.rheight() functions. Finally, the width and height can be swapped using the PySide.QtCore.QSize.transpose() function.

The PySide.QtCore.QSize.isValid() function determines if a size is valid (a valid size has both width and height greater than zero). The PySide.QtCore.QSize.isEmpty() function returns true if either of the width and height is less than, or equal to, zero, while the PySide.QtCore.QSize.isNull() function returns true only if both the width and the height is zero.

Use the PySide.QtCore.QSize.expandedTo() function to retrieve a size which holds the maximum height and width of this size and a given size. Similarly, the PySide.QtCore.QSize.boundedTo() function returns a size which holds the minimum height and width of this size and a given size.

PySide.QtCore.QSize objects can be streamed as well as compared.
