TODO/ Ideas

• add example with salsa or some other incremental computation lib
• IO
  • all Mouse/ Modifier helpers

nice to have:

• use Serde to make it possible to declare graphs and render them
  • load and save as well using imnode_* functions
• add comments to everything
  • figure out good descriptions of coordinate systems
• review types in unsafe code
  • especially -> &mut sys::Style

Example (see imnodes-wgpu-examples/src/hello_world.rs)

use imgui::{im_str, Ui};
use imnodes::{editor, PinShape};

pub fn show(ui: &Ui, context: &mut imnodes::EditorContext) {
    let mut id_gen = context.new_identifier_generator();

    editor(context, |mut editor| {
        editor.add_node(id_gen.next_node(), |mut node| {
            node.add_titlebar(|| {
                ui.text(im_str!("simple node :)"));
            });

            node.add_input(id_gen.next_input_pin(), PinShape::Circle, || {
                ui.text(im_str!("input"));
            });

            node.add_output(id_gen.next_output_pin(), PinShape::QuadFilled, || {
                ui.text(im_str!("output"));
            });
        });
    });
}
