WinSafe

Windows API and GUI in safe, idiomatic Rust.

WinSafe has:

• low-level Win32 API constants, functions and structs;
• high-level structs to build native Win32 GUI applications.

If you're looking for a comprehensive Win32 coverage, take a look at winapi or windows crates, which are unsafe, but have everything.

WinSafe documentation:

Current status

These are the estimated progresses of the GUI features:

Plus, below are the numbers of native FFI items implemented:

Usage

Add the dependency in your Cargo.toml:

[dependencies]
winsafe = { version = "0.0.16", features = [] }

You can, alternatively, use the Nightly (master) branch directly, to get the latest features right away:

[dependencies]
winsafe = { git = "https://github.com/rodrigocfd/winsafe", features = [] }

Then you must enable the Cargo features you want to be included – these modules are named after native Windows DLL and library names, mostly.

The following Cargo features are available so far:

Note that a Cargo feature may depend on other features, which will be enabled automatically.

Example

Note: You can find several examples in the dedicated repo: github.com/rodrigocfd/winsafe-examples

WinSafe allows you to create windows in two ways:

• programmatically defining parameters; or
• loading dialogs from a .res file created with a WYSIWYG resource editor.

The example below creates a window with a button programmatically. Note how the click event is handled with a closure:

[dependencies]
winsafe = { version = "0.0.16", features = ["gui"] }

#![windows_subsystem = "windows"]

use winsafe::prelude::*;
use winsafe::{gui, POINT, SIZE};

fn main() {
    let my = MyWindow::new(); // instantiate our main window
    if let Err(e) = my.wnd.run_main(None) { // ... and run it
        eprintln!("{}", e);
    }
}


#[derive(Clone)]
pub struct MyWindow {
    wnd:       gui::WindowMain, // responsible for managing the window
    btn_hello: gui::Button,     // a button
}

impl MyWindow {
    pub fn new() -> Self {
        let wnd = gui::WindowMain::new( // instantiate the window manager
            gui::WindowMainOpts {
                title: "My window title".to_owned(),
                size: (300, 150),
                ..Default::default() // leave all other options as default
            },
        );

        let btn_hello = gui::Button::new(
            &wnd, // the window manager is the parent of our button
            gui::ButtonOpts {
                text: "&Click me".to_owned(),
                position: (20, 20),
                ..Default::default()
            },
        );

        let new_self = Self { wnd, btn_hello };
        new_self.events(); // attach our events
        new_self
    }

    fn events(&self) {
        let wnd = self.wnd.clone(); // clone so it can be passed into the closure
        self.btn_hello.on().bn_clicked(move || {
            wnd.hwnd().SetWindowText("Hello, world!")?;
            Ok(())
        });
    }
}
