0.27.1 - 2024-03-29

🐛 Fixed

🔧 Changed

0.27.0 - 2024-03-26 - Nicer menus and new hit test logic

The hit test logic (what is the user clicking on?) has been completely rewritten, and should now be much more accurate and helpful. The hit test and interaction logic is run at the start of the frame, using the widgets rects from the previous frame, but the latest mouse coordinates. It enabled getting a Response for a widget before creating it using Context::read_response. This will in the future unlock more powerful widget styling options. The new hit test also allows clicking slightly outside a button and still hit it, improving the support for touch screens.

The menus have also been improved so that they both act and feel better, with no change in API. Included in this is much nicer looking shadows, supporting an offset.

⚠️ BREAKING

Response::clicked* and Response::dragged* may lock the Context, so don't call it from a Context-locking closure.
Response::clicked_by will no longer be true if clicked with keyboard. Use Response::clicked instead.
Memory::focus has been renamed Memory::focused

For integrations

There are several changes relevant to integrations.

Added crate::RawInput::viewports with information about all active viewports
The repaint callback set by Context::set_request_repaint_callback now points to which viewport should be repainted

If you support viewports, you need to call Context::set_embed_viewports(false), or all new viewports will be embedded (the default behavior)

0.23.0 - 2023-09-27 - New image API

This release contains a simple and powerful image API:

// Load from web:
ui.image("https://www.example.com/some_image.png");

// Include image in the binary using `include_bytes`:
ui.image(egui::include_image!("../assets/ferris.svg"));

// With options:
ui.add(
    egui::Image::new("file://path/to/image.jpg")
        .max_width(200.0)
        .rounding(10.0),
);

The API is based on a plugin-system, where you can tell egui how to load the images, and from where.

egui_extras comes with loaders for you, so all you need to do is add the following to your Cargo.toml:

egui_extras = { version = "0.23", features = ["all_loaders"] }
image = { version = "0.24", features = ["jpeg", "png"] } # Add the types you want support for

And this to your code:

egui_extras::install_image_loaders(egui_ctx);
