This allows you to transform widgets without having to put them on a new
layer.
Example usage:
https://github.com/user-attachments/assets/6b547782-f15e-42ce-835f-e8febe8d2d65
```rust
use eframe::egui;
use eframe::egui::{Button, Frame, InnerResponse, Label, Pos2, RichText, UiBuilder, Widget};
use eframe::emath::TSTransform;
use eframe::NativeOptions;
use egui::{CentralPanel, Sense, WidgetInfo};
pub fn main() -> eframe::Result {
eframe::run_simple_native("focus test", NativeOptions::default(), |ctx, _frame| {
CentralPanel::default().show(ctx, |ui| {
let response = ui.ctx().read_response(ui.next_auto_id());
let pressed = response
.as_ref()
.is_some_and(|r| r.is_pointer_button_down_on());
let hovered = response.as_ref().is_some_and(|r| r.hovered());
let target_scale = match (pressed, hovered) {
(true, _) => 0.94,
(_, true) => 1.06,
_ => 1.0,
};
let scale = ui
.ctx()
.animate_value_with_time(ui.id().with("Down"), target_scale, 0.1);
let mut center = response
.as_ref()
.map(|r| r.rect.center())
.unwrap_or_else(|| Pos2::new(0.0, 0.0));
if center.any_nan() {
center = Pos2::new(0.0, 0.0);
}
let transform = TSTransform::from_translation(center.to_vec2())
* TSTransform::from_scaling(scale)
* TSTransform::from_translation(-center.to_vec2());
ui.with_visual_transform(transform, |ui| {
Button::new(RichText::new("Yaaaay").size(20.0))
.sense(Sense::click())
.ui(ui)
});
});
})
}
