Detailed Description

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

A size is specified by a PySide.QtCore.QSizeF.width() and a PySide.QtCore.QSizeF.height() . It can be set in the constructor and changed using the PySide.QtCore.QSizeF.setWidth() , PySide.QtCore.QSizeF.setHeight() , or PySide.QtCore.QSizeF.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.QSizeF.rwidth() and PySide.QtCore.QSizeF.rheight() functions. Finally, the width and height can be swapped using the PySide.QtCore.QSizeF.transpose() function.

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

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

The PySide.QtCore.QSizeF class also provides the PySide.QtCore.QSizeF.toSize() function returning a PySide.QtCore.QSize copy of this size, constructed by rounding the width and height to the nearest integers.

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

PySide.QtCore.QSizeF.expandedTo() PySide.QtCore.QSizeF.scale()

PySide.QtCore.QSizeF.expandedTo(arg__1)

Parameters:arg__1 – PySide.QtCore.QSizeF Return type:PySide.QtCore.QSizeF

Returns a size holding the maximum width and height of this size and the given otherSize .

See also

PySide.QtCore.QSizeF.boundedTo() PySide.QtCore.QSizeF.scale()

PySide.QtCore.QSizeF.height()

Return type:PySide.QtCore.qreal

Returns the height.

See also

PySide.QtCore.QSizeF.width() PySide.QtCore.QSizeF.setHeight()

PySide.QtCore.QSizeF.isEmpty()

Return type:PySide.QtCore.bool

Returns true if either of the width and height is less than or equal to 0; otherwise returns false.

See also

PySide.QtCore.QSizeF.isNull() PySide.QtCore.QSizeF.isValid()

PySide.QtCore.QSizeF.isNull()

Return type:PySide.QtCore.bool

Returns true if both the width and height are +0.0; otherwise returns false.

Note

Since this function treats +0.0 and -0.0 differently, sizes with zero width and height where either or both values have a negative sign are not defined to be null sizes.
