Module dnd 

Flexible API for drag-and-drop and reordering.

• Any UI widget or layout can be made draggable
• Any UI widget or layout can be given a handle for dragging
• Any UI widget or layout can be made a target for dragging
• Any UI widget or layout can be made a target for reordering
• Multiple separate drag-and-drop environments can coexist and even overlap in the same UI

Examples

use hcegui::*;

let mut elements = vec!["point", "line", "plane", "space"];
let mut dnd = reorder::Dnd::new(ui.ctx(), ui.next_auto_id());
for (i, &elem) in elements.iter().enumerate() {
    dnd.reorderable_with_handle(ui, i, |ui, _| ui.label(elem));
}
if let Some(r) = dnd.finish(ui).if_done_dragging() {
    r.reorder_vec(&mut elements);
}
