Crate egui_drag_value_expr

egui_drag_value_expr

An egui DragValue widget that accepts expression-based values.

Usage

A rhai::Scope can be passed to the DragValueExpr widget to allow the user to enter expressions that reference variables in the scope.

With a scope:

let mut scope = rhai::Scope::new();
scope.push("ten", 10.);
ui.add(DragValueExpr::new(&mut self.value, Some(&scope)));

Without a scope:

ui.add(DragValueExpr::new(&mut self.value, None));

Structs
