Struct QSizeF 

pub struct QSizeF { /* private fields */ }

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

Implementations

impl QSizeF

pub fn bounded_to(&self, other_size: &QSizeF) -> QSizeF

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

pub fn expanded_to(&self, other_size: &QSizeF) -> QSizeF

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

pub fn height(&self) -> f64

Returns the height.

pub fn is_empty(&self) -> bool

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

pub fn is_null(&self) -> bool

Returns true if both the width and height are 0.0 (ignoring the sign); otherwise returns false.

pub fn is_valid(&self) -> bool

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

pub fn grown_by(&self, margins: QMarginsF) -> QSizeF

Returns the size that results from growing this size by margins.

pub fn scale(&mut self, size: &QSizeF, mode: AspectRatioMode)

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

pub fn scaled(&self, s: &QSizeF, mode: AspectRatioMode) -> QSizeF

Returns a size scaled to a rectangle with the given size s, according to the specified mode.

pub fn set_height(&mut self, height: f64)

Sets the height to the given finite height.

pub fn set_width(&mut self, width: f64)

Sets the width to the given finite width.

pub fn shrunk_by(&self, margins: QMarginsF) -> QSizeF

Returns the size that results from shrinking this size by margins.

pub fn to_size(&self) -> QSize

Returns an integer based copy of this size.

Note that the coordinates in the returned size will be rounded to the nearest integer.

pub fn transpose(&mut self)

Swaps the width and height values.

pub fn transposed(&self) -> QSizeF

Returns the size with width and height values swapped.

pub fn width(&self) -> f64

Returns the width.

impl QSizeF

pub fn new(w: f64, h: f64) -> Self

Constructs a size with the given width and height.
