Struct QMarginsF 

pub struct QMarginsF { /* private fields */ }

The QMarginsF class defines the four margins of a rectangle.

Implementations

impl QMarginsF

pub fn bottom(&self) -> f64

Returns the bottom margin.

pub fn is_null(&self) -> bool

Returns true if all margins are very close to 0; otherwise returns false.

pub fn left(&self) -> f64

Returns the left margin.

pub fn right(&self) -> f64

Returns the right margin.

pub fn set_bottom(&mut self, bottom: f64)

Sets the bottom margin to abottom (which must be finite).

pub fn set_left(&mut self, left: f64)

Sets the left margin to aleft (which must be finite).

pub fn set_right(&mut self, right: f64)

Sets the right margin to aright (which must be finite).

pub fn set_top(&mut self, top: f64)

Sets the top margin to atop (which must be finite).

pub fn to_margins(&self) -> QMargins

Returns an integer-based copy of this margins object.

Note that the components in the returned margins will be rounded to the nearest integer.

pub fn top(&self) -> f64

Returns the top margin.

impl QMarginsF

pub fn new(left: f64, top: f64, right: f64, bottom: f64) -> Self

Constructs margins with the given left, top, right, and bottom. All parameters must be finite.
