Detailed Description#

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.

Adds the given size to this size, and returns a reference to this size. For example:

s = QSize( 3, 7)
r = QSize(-1, 4)
s += r
# s becomes (2,11)
PySide6.QtCore.QSize.__sub__(s2)#

Return type:

PySide6.QtCore.QSize

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Subtracts the given size from this size, and returns a reference to this size. For example:

s = QSize( 3, 7)
r = QSize(-1, 4)
s -= r
# s becomes (4,3)
PySide6.QtCore.QSize.__div__(c)#

PySide6.QtCore.QSize.scale(s, mode)#
Parameters:

This is an overloaded function.

PySide6.QtCore.QSize.scale(w, h, mode)
Parameters:

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Scales the size to a rectangle with the given width and height, according to the specified mode:

  • If mode is IgnoreAspectRatio , the size is set to (width, height).

  • If mode is KeepAspectRatio , the current size is scaled to a rectangle as large as possible inside (width, height), preserving the aspect ratio.

  • If mode is KeepAspectRatioByExpanding , the current size is scaled to a rectangle as small as possible outside (width, height), preserving the aspect ratio.

Example:

t1 = QSize(10, 12)
t1.scale(60, 60, Qt.IgnoreAspectRatio)
# t1 is (60, 60)
t2 = QSize(10, 12)
t2.scale(60, 60, Qt.KeepAspectRatio)
# t2 is (50, 60)
t3 = QSize(10, 12)
t3.scale(60, 60, Qt.KeepAspectRatioByExpanding)
# t3 is (60, 72)
