Get main window's position coordinates

[mrkaragoz]

Hello guys. Is there a way to get the main window's current position coordinates? I would like to save them in a config file and start the app in the same position with initial_window_pos (without the persistence feature)

It could be something like this:

fn on_exit_event(&mut self) -> bool {
    MyApp::update_config_for_window_pos(something::something::something::get_current_window_pos());  // function to update config
    return true
}

In commit 3c685d7 @TicClick added WindowInfo. This provides position and size information of the native window. This info available with eframe::Frame::info().window_info. As of writing this answer, it is not included in the latest version of egui (0.18.1) and eframe (0.18.0). In order to use this feature update the Cargo.toml as follows:

[dependencies]
egui = { git = "https://github.com/emilk/egui"}
eframe = { git = "https://github.com/emilk/egui"}

After that, it is possible to:

impl eframe::App for MyApp {
    fn update(&mut self, ctx: &egui::Context, frame: &mut eframe::Frame) {
        let window_info = frame.info.window_info.clone();
    }
}

Looks like window_info is no longer present, but #2696 suggests

use Context::screen_rect or InputState::screen_rect (same thing)
but that doesn't seem to have the position I was expecting, perhaps it's saying 0,0 because egui is drawing inside the whole window but that screen rect isn't aware of the OS window stuff, only it's area inside it
