WinSafe

Windows API and GUI in safe, idiomatic Rust.

WinSafe has:

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

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:

• stable release: docs.rs/winsafe
• master branch: rodrigocfd.github.io/winsafe/winsafe

Current status

This crate is still in alpha stage. Below is an estimated progress of feature groups:

Feature group	Estimated progress
User windows (main, modal and control)
Native controls
Window messages
Overall Win32 APIs

Usage

Add the dependency in your Cargo.toml:

[dependencies]
winsafe = { version = "0.0.9", 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:

Feature	Description
advapi	Advapi32.dll, for Windows Registry
comctl	ComCtl32.dll, for Common Controls
comdlg	ComDlg32.dll, for the old Common Dialogs
dshow	DirectShow
gdi	Gdi32.dll, the Windows GDI
gui	The WinSafe high-level GUI structs
kernel	Kernel32.dll, all others will include it
msimg	Msimg32.dll
ole	OLE and basic COM support
oleaut	OLE Automation
shell	Shell32.dll, the COM-based Windows Shell
shlwapi	Shlwapi.dll, for some Shell functions
user	User32.dll, the basic Windows GUI support
uxtheme	UxTheme.dll, extended window theming
version	Version.dll, to manipulate *.exe version info

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 = "0.0.9", features = ["gui"] }

#![windows_subsystem = "windows"]

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

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() -> MyWindow {
        let wnd = gui::WindowMain::new( // instantiate the window manager
            gui::WindowMainOpts {
                title: "My window title".to_owned(),
                size: SIZE::new(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: POINT::new(20, 20),
                ..Default::default()
            },
        );

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

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