pub struct PickWidgets { /* fields omitted */ }

A node "walker" that yields all widgets under the given xy position in order from top to bottom.

Methods

impl PickWidgets

fn next_including_graphics_children(
    &mut self,
    graph: &Graph,
    depth_order: &[Id],
    theme: &Theme
) -> Option<Id>

The next widget::Id under the xy location.

Unlike the PickWidgets::next method, this method ignores whether or not the next widget is a Graphics child to some other widget.

This is called within PickWidgets::next.

fn next(
    &mut self,
    graph: &Graph,
    depth_order: &[Id],
    theme: &Theme
) -> Option<Id>

The widget::Id of the next Widget under the xy location.

The Graph is traversed from the top down.

If the next widget is some graphic element of another widget, the graphic parent will be returned.
