Detailed Description

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 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.

Constructor & Destructor Documentation

QtCore.QSize.QSize ( System.Type  dummy )

protected

QtCore.QSize.QSize

(

)

Constructs a size with an invalid width and height (i.e., isValid() returns false).

See also isValid().

QtCore.QSize.QSize

(

QSize

copy

)

Constructs a size with an invalid width and height (i.e., isValid() returns false).

See also isValid().

QtCore.QSize.QSize	(	int	w,
		int	h
	)

Constructs a size with the given width and height.

See also setWidth() and setHeight().

Member Function Documentation

new QSize QtCore.QSize.BoundedTo

(

QSize

arg1

)

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

See also expandedTo() and scale().

new void QtCore.QSize.Dispose

(

)

override bool QtCore.QSize.Equals

object

o

)

new QSize QtCore.QSize.ExpandedTo

(

QSize

arg1

)

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

See also boundedTo() and scale().

override int QtCore.QSize.GetHashCode

(

)

new bool QtCore.QSize.IsEmpty

(

)

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

See also isNull() and isValid().

new bool QtCore.QSize.IsNull

(

)

Returns true if both the width and height is 0; otherwise returns false.

See also isValid() and isEmpty().

new bool QtCore.QSize.IsValid

(

)

Returns true if both the width and height is equal to or greater than 0; otherwise returns false.

See also isNull() and isEmpty().

static bool QtCore.QSize.operator!= ( QSize  arg1, QSize  arg2  )

static

static QSize QtCore.QSize.operator* ( QSize  arg1, double  arg2  )

static

Multiplies the given size by the given factor, and returns the result rounded to the nearest integer.

See also QSize::scale().

static QSize QtCore.QSize.operator+ ( QSize  arg1, QSize  arg2  )

static

Returns the sum of s1 and s2; each component is added separately.

static QSize QtCore.QSize.operator- ( QSize  arg1, QSize  arg2  )

static

Returns s2 subtracted from s1; each component is subtracted separately.

static QSize QtCore.QSize.operator/ ( QSize  arg1, double  arg2  )

static

This is an overloaded function.

Divides the given size by the given divisor, and returns the result rounded to the nearest integer.

See also QSize::scale().

static bool QtCore.QSize.operator== ( QSize  arg1, QSize  arg2  )

static

new int QtCore.QSize.Rheight

(

)

Returns a reference to the height.

Using a reference makes it possible to manipulate the height directly. For example:

QSize size(100, 10);

size.rheight() += 5;

// size becomes (100,15)

See also rwidth() and setHeight().

new int QtCore.QSize.Rwidth

(

)

Returns a reference to the width.

Using a reference makes it possible to manipulate the width directly. For example:

QSize size(100, 10);

size.rwidth() += 20;

// size becomes (120,10)

See also rheight() and setWidth().

new void QtCore.QSize.Scale	(	QSize	s,
		Qt.AspectRatioMode	mode
	)

This is an overloaded function.

Scales the size to a rectangle with the given size, according to the specified mode.

new void QtCore.QSize.Scale	(	int	w,
		int	h,
		Qt.AspectRatioMode	mode
	)

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

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

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

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

Example:

QSize t1(10, 12);

t1.scale(60, 60, Qt::IgnoreAspectRatio);

// t1 is (60, 60)

QSize t2(10, 12);

t2.scale(60, 60, Qt::KeepAspectRatio);

// t2 is (50, 60)

QSize t3(10, 12);

t3.scale(60, 60, Qt::KeepAspectRatioByExpanding);

// t3 is (60, 72)

See also setWidth() and setHeight().

new void QtCore.QSize.Transpose

(

)

Swaps the width and height values.

See also setWidth() and setHeight().
