Struct Prepared

pub struct Prepared {
    pub frame: Frame,
    pub content_ui: Ui,
    /* private fields */
}

Implementations

impl Prepared

pub fn allocate_space(&self, ui: &mut Ui) -> Response

Allocate the space that was used by Self::content_ui.

This MUST be called, or the parent ui will not know how much space this widget used.

This can be called before or after Self::paint.

pub fn paint(&self, ui: &Ui)

Paint the frame.

This can be called before or after Self::allocate_space.

pub fn end(self, ui: &mut Ui) -> Response

Convenience for calling Self::allocate_space and Self::paint.

Returns the outer rect, i.e. including the outer margin.
