#[repr(C)]pub struct QSize { /* private fields */ }
Expand description
The QSize class defines the size of a two-dimensional object using integer point precision.
C++ class: QSize
.
The QSize class defines the size of a two-dimensional object using integer point precision.
A size is specified by a width() and a height(). It can be set in the constructor and changed using the setWidth(), setHeight(), or scale() functions, or using arithmetic operators. A size can also be manipulated directly by retrieving references to the width and height using the rwidth() and rheight() functions. Finally, the width and height can be swapped using the transpose() function.
The isValid() function determines if a size is valid (a valid size has both width and height greater than or equal to zero). The isEmpty() function returns true
if either of the width and height is less than, or equal to, zero, while the isNull() function returns true
only if both the width and the height is zero.
Use the expandedTo() function to retrieve a size which holds the maximum height and width of this size and a given size. Similarly, the boundedTo() function returns a size which holds the minimum height and width of this size and a given size.
QSize objects can be streamed as well as compared.
