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.

Current status

Native FFI items implemented

Native FFI item	Count
Functions	908
Structs	264
Constants	15,131
Window messages	684
Handles	54
COM interfaces	98
COM methods	643

Although WinSafe already has a lot of Win32 APIs, it doesn't have everything, simply because Win32 API is gigantic. So if you're looking for a comprehensive Win32 coverage, take a look at winapi or windows crates, which are unsafe, but have everything.

High-level GUI controls implemented

• User custom window/dialog – main, modal, modeless, control, message-only.
• Native controls – button, check box, combo box, date and time picker, edit, header, label, list box, list view, month calendar, progress bar, radio button, status bar, tab, track bar, tree view, up down.

Usage

Add the dependency in your Cargo.toml:

[dependencies]
winsafe = { version = "0.0.27", 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.

Cargo features

The APIs in WinSafe are split into Cargo features to speed up compilation time. Only the features you include will be compiled.

The following Cargo features are available so far:

Feature	Description
advapi	Advapi32.dll and Ktmw32.dll, advanced kernel functions
comctl	ComCtl32.dll, the Common Controls
dshow	DirectShow
dwm	Desktop Window Manager
dxgi	DirectX Graphics Infrastructure
gdi	Gdi32.dll, the Windows GDI
gui	The WinSafe high-level GUI abstractions
kernel	Kernel32.dll, basic kernel functions
mf	Media Foundation
ole	Basic OLE/COM support
oleaut	OLE Automation
psapi	Process Status API
raw-dylib	Enables raw-dylib linking
shell	Shell32.dll, Shlwapi.dll, and Userenv.dll, the COM-based Windows Shell
taskschd	Task Scheduler
user	User32.dll and ComDlg32.dll, the basic Windows GUI support
uxtheme	UxTheme.dll, extended window theming
version	Version.dll, to manipulate *.exe version info
wininet	Windows Internet
winspool	Print Spooler API

Don't worry about including dependency features. Once you use a feature, Cargo will add and resolve all dependencies 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 = "0.0.27", features = ["gui"] }

#![windows_subsystem = "windows"]

use winsafe::{self as w, gui, prelude::*};

fn main() {
    if let Err(e) = MyWindow::create_and_run() {
        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 create_and_run() -> w::AnyResult<i32> {
        let wnd = gui::WindowMain::new(
            // instantiate the window manager
            gui::WindowMainOpts {
                title: "My window title",
                size: gui::dpi(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",
                position: gui::dpi(20, 20),
                ..Default::default()
            },
        );

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

        new_self.wnd.run_main(None) // show the main window; will block until closed
    }

    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!")?; // call native Windows API
            Ok(())
        });
    }
}
