Struct qt_core::LayoutDirection

pub struct LayoutDirection(/* private fields */);

Specifies the direction of Qt's layouts and text handling.

C++ enum: Qt::LayoutDirection.

C++ documentation:

Specifies the direction of Qt’s layouts and text handling.

Right-to-left layouts are necessary for certain languages, notably Arabic and Hebrew.

LayoutDirectionAuto serves two purposes. When used in conjunction with widgets and layouts, it will imply to use the layout direction set on the parent widget or QApplication. This has the same effect as QWidget::unsetLayoutDirection().

When LayoutDirectionAuto is used in conjunction with text layouting, it will imply that the text directionality is determined from the content of the string to be layouted.

See also QGuiApplication::setLayoutDirection(), QWidget::setLayoutDirection(), QTextOption::setTextDirection(), and QString::isRightToLeft().

Implementations

impl LayoutDirection

pub fn to_int(&self) -> c_int

impl LayoutDirection

pub const LeftToRight: LayoutDirection = _

Left-to-right layout. (C++ enum variant: LeftToRight = 0)

pub const RightToLeft: LayoutDirection = _

Right-to-left layout. (C++ enum variant: RightToLeft = 1)

pub const LayoutDirectionAuto: LayoutDirection = _

Automatic layout. (C++ enum variant: LayoutDirectionAuto = 2)

Trait Implementations

impl Clone for LayoutDirection

fn clone(&self) -> LayoutDirection

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LayoutDirection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<LayoutDirection> for c_int

fn from(value: LayoutDirection) -> Self

Converts to this type from the input type.

impl From<i32> for LayoutDirection

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for LayoutDirection

fn eq(&self, other: &LayoutDirection) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
