Struct CallbacksOfHitTest

pub struct CallbacksOfHitTest {
    pub nodes_with_callbacks: BTreeMap<NodeId, DetermineCallbackResult>,
    pub needs_relayout_anyways: bool,
    pub needs_redraw_anyways: bool,
}

Fields

nodes_with_callbacks: BTreeMap<NodeId, DetermineCallbackResult>

A BTreeMap where each item is already filtered by the proper hit-testing type, meaning in order to get the proper callbacks, you simply have to iterate through all node IDs

needs_relayout_anyways: bool

Same as needs_redraw_anyways, but for reusing the layout from the previous frame. Each :hover and :active group stores whether it modifies the layout, as a performance optimization.

needs_redraw_anyways: bool

Whether the screen should be redrawn even if no Callback returns an UpdateScreen::Redraw. This is necessary for :hover and :active mouseovers - otherwise the screen would only update on the next resize.
