This crate provides support functions to simplify integrating imgui-rs with glutin.
Using the library
In your initialization code call configure_keys
:
use imgui::ImGui;
let mut imgui = ImGui::init();
imgui_glutin_support::configure_keys(&mut imgui);
In your main loop you should already be retrieving events from glutin and handling them. All
you need to do is pass each event to imgui_glutin_support
as well:
events_loop.poll_events(|event| {
// do application-specific stuff with event
imgui_glutin_support::handle_event(&mut imgui, &event);
});
Advanced use cases
In more advanced use cases you might want to handle and filter events yourself and call some of the various smaller helper functions exported by the library.
For example, you might want to customize mouse wheel line scrolling amount:
events_loop.poll_events(|event| {
// do application-specific stuff with event
// default handling for events
imgui_glutin_support::handle_event(&mut imgui, &event);
// Scroll 10 times the pixels per line by handling LineDelta events again and
// overriding the mouse wheel value
if let Event::WindowEvent { event, .. } = event {
match event {
WindowEvent::MouseWheel {
delta: MouseScrollDelta::LineDelta(_, lines),
phase: TouchPhase::Moved,
..
} => {
imgui.set_mouse_wheel(lines * 10.0);
}
_ => ()
}
}
});
