Detailed Description¶
The QSize class defines the size of a two-dimensional object using integer point precision.
A size is specified by a QSize.width() and a QSize.height() . It can be set in the constructor and changed using the QSize.setWidth() , QSize.setHeight() , or QSize.scale() functions, or using arithmetic operators. A size can also be manipulated directly by retrieving references to the width and height using the QSize.rwidth() and QSize.rheight() functions. Finally, the width and height can be swapped using the QSize.transpose() function.
The QSize.isValid() function determines if a size is valid (a valid size has both width and height greater than zero). The QSize.isEmpty() function returns true if either of the width and height is less than, or equal to, zero, while the QSize.isNull() function returns true only if both the width and the height is zero.
Use the QSize.expandedTo() function to retrieve a size which holds the maximum height and width of this size and a given size. Similarly, the QSize.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.
- class PySide.QtCore.QSize(QSize)¶
- class PySide.QtCore.QSize
- class PySide.QtCore.QSize(w, h)
Parameters: - w – int
- h – int
- QSize – QSize
Constructs a size with an invalid width and height (i.e., QSize.isValid() returns false).

Parameter: s2 – QSize Return type: bool
- QSize.__mul__(c)¶
Parameter: c – qreal Return type: QSize
- QSize.__mul__(c)
Parameter: c – qreal Return type: QSize
- QSize.__imul__(c)¶

- QSize.__add__(s2)¶
Parameter: s2 – QSize Return type: QSize
- QSize.__iadd__(arg__1)¶
Parameter: arg__1 – QSize Return type: QSize 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)
- QSize.__sub__(s2)¶
Parameter: s2 – QSize Return type: QSize
- QSize.__isub__(arg__1)¶
Parameter: arg__1 – QSize Return type: QSize 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)
- QSize.__div__(c)¶
Parameter: c – qreal Return type: QSize
- QSize.__idiv__(c)¶
Parameter: c – qreal Return type: QSize This is an overloaded function.
Divides both the width and height by the given divisor , and returns a reference to the size.
Note that the result is rounded to the nearest integer.
