Detailed Description

Side constants named from the right-to-left perspective.

These names express the RTL perspective for APIs that mirror sides according to the application's layout direction, such as WWidget::setFloatSide() and WWidget::setOffsets(). In these APIs, RtlSide::Left is left in RTL and right in LTR, while RtlSide::Right is right in RTL and left in LTR.

The constants have type Side. RtlSide::Left equals Side::Right and RtlSide::Right equals Side::Left. The other constants retain their matching Side values. These values do not change dynamically with the application's layout direction and do not alter the behavior of the API that uses them.

The constants can be passed directly to APIs taking Side or WFlags<Side>. Combine them with the bitwise OR operator, for example RtlSide::Left | RtlSide::Top, or mix them with Side values, for example RtlSide::Left | Side::Top. Both combinations have type WFlags<Side> and equal Side::Right | Side::Top.

RtlSide::CenterX and RtlSide::CenterY, or their combination, are only valid for WCssDecorationStyle::setBackgroundImage(), just like the corresponding Side values.
