Struct RelativeLayout

pub struct RelativeLayout {
    pub placement: RelativePlacement,
    pub auto_hide: RelativeAutoHide,
    pub auto_hide_request: Callback<()>,
    pub uncovered_controls: Vec<Weak<RefCell<dyn ControlObject>>>,
}

Warning!

RelativeLayout is designed to work with Popup control and it’s dangerous (danger of panic) to use outside of it.

It works correctly only when:

1. Covers whole window.
2. References only controls on lower layouts.

The lower layout control is a control that:

• is not lying on the path from RelativeLayout to root (that would cause borrow panic during layout phase)
• it’s layout phase is calculated before the layout phase of RelativeLayout (RelativeLayout refers to calculated size of that control)

Fields

placement: RelativePlacement

auto_hide: RelativeAutoHide

Auto hide method. Defines rules when to call auto_hide_request callback.

auto_hide_request: Callback<()>

Called when auto hide is requested.

uncovered_controls: Vec<Weak<RefCell<dyn ControlObject>>>

RelativeLayout does not pass through events to controls below except the area covered by this list of controls

Implementations

impl RelativeLayout

pub fn builder() -> RelativeLayoutBuilder<((), (), (), ())>

Create a builder for building RelativeLayout. On the builder, call .placement(...)(optional), .auto_hide(...)(optional), .auto_hide_request(...)(optional), .uncovered_controls(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of RelativeLayout.

impl RelativeLayout

pub fn to_view( self, style: Option<Box<dyn Style<Self>>>, context: ViewContext, ) -> Rc<RefCell<dyn ControlObject>>
