Module slint::platform

source ·
Expand description

This module contains items that you need to use or implement if you want use Slint in an environment without one of the supplied platform backends such as qt or winit.

The primary interface is the platform::Platform trait. Pass your implementation of it to Slint by calling platform::set_platform() early on in your application, before creating any Slint components.

The Slint on Microcontrollers documentation has additional examples.


This module contains the SoftwareRenderer and related types.


The Key enum is used to map a specific key by name e.g. Key::Control to an internal used unicode representation. The enum is convertible to std::char and slint::SharedString. Use this with slint::platform::WindowEvent to supply key events to Slint’s platform abstraction.
This enum describes the different types of buttons for a pointer event, typically on a mouse or a pencil.
This enum describes the different error scenarios that may occur when set_platform fails.
A event that describes user input.


Trait that is returned by the Platform::new_event_loop_proxy
This trait defines the interface between Slint and platform APIs typically provided by operating and windowing systems.
This trait represents the adaptation layer between the Window API, and the internal type from the backend that provides functionality such as device-independent pixels, window resizing, and other typically windowing system related tasks.


Returns the duration before the next timer is expected to be activated. This is the largest amount of time that you can wait before calling update_timers_and_animations().
Set the Slint platform abstraction.
Call this function to update and potentially activate any pending timers, as well as advance the state of any active animtaions.
