Crate fltk_egui

fltk-egui

An FLTK backend for Egui using a GlWindow. The code is largely based on https://github.com/ArjunNair/egui_sdl2_gl modified for fltk-rs.

Usage

Add to your Cargo.toml:

[dependencies]
fltk-egui = "0.3"

The basic premise is that egui is an immediate mode gui, while FLTK is retained. To be able to run Egui code, events and redrawing would need to be handled/done in the FLTK event loop. The events are those of the GlWindow, which are sent to egui’s event handlers. Other FLTK widgets can function also normally since there is no interference from Egui.

Examples

To run the examples, just run:

$ cargo run --example demo_windows
$ cargo run --example triangle
$ cargo run --example basic
$ cargo run --example embedded
