Implementing custom-shaped buttons that work with .clicked()

[aethertap]

I'm trying to create a button that takes an arbitrary polygon as its clickable shape (as part of a radial menu). I have almost everything working, except that I can't override the default behavior of Response::clicked(), which always assumes a rectangular shape. I have accurate hit detection for the shape, and within the widget's ui function I disable the Sense::CLICK on response.sense. As long as the calling code checks response.sense.senses_click() && response.clicked() it works as expected, at least for one button with no overlaps (haven't tested that yet).

I'd really like to get a bit more control over how the clicked() function works from Response though, if possible. Has anyone gotten something like that to work?

Here's what the code to interact with it would look if it worked the way I want it to:

// Make the shape for the button
let btn_shape = Shape::convex_polygon(
    vec![
        (0.,0.).into(),
        (50.,100.).into(),
        (100.,0.).into()],
    Color32::from_rgb(100,100,100), 
    PathStroke::new(2.0,Color32::from_rgb(255,255,255)));

// Add the button as usual
let res = ui.put(Rect::from_center_size( 
        (50.,50.).into(), 
        (100.,100.).into()),
    ShapeButton::new(btn_shape));

// Respond to clicks. This currently works if I change that test 
// to include res.sense.senses_click()
if res.clicked() {
    println!("Response: {res:#?}");
    println!("Clicked the triangle button");
    if !res.sense.senses_click() {
        println!("should not have gotten click");
    }
}

Here is an example of a custom widget (used in egui.rs website demo)
