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.

WinSafe documentation:

| Branch | Docs |
| - | - |
| Stable | [docs.rs/winsafe](https://docs.rs/winsafe) |
| Nightly (master) | [rodrigocfd.github.io/winsafe/winsafe](https://rodrigocfd.github.io/winsafe/winsafe/) |

## Current status

### Native FFI items implemented

| Native FFI item | Count |
| - | -: |
| Functions | 783 |
| Structs | 237 |
| Constants | 13,417 |
| Window messages | 655 |
| Handles | 45 |
| COM interfaces | 90 |
| COM methods | 541 |

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](https://crates.io/crates/winapi) or [windows](https://crates.io/crates/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`:

```toml
[dependencies]
winsafe = { version = "0.0.22", features = [] }
```

You can, alternatively, use the Nightly (master) branch [directly](https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-git-repositories), to get the latest features right away:

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

Then you must enable the [Cargo features](https://doc.rust-lang.org/cargo/reference/features.html#the-features-section) 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](https://learn.microsoft.com/en-us/windows/win32/api/_controls/) |
| `dshow` | [DirectShow](https://learn.microsoft.com/en-us/windows/win32/directshow/directshow) |
| `dwm` | [Desktop Window Manager](https://learn.microsoft.com/en-us/windows/win32/dwm/dwm-overview) |
| `dxgi` | [DirectX Graphics Infrastructure](https://learn.microsoft.com/en-us/windows/win32/direct3ddxgi/dx-graphics-dxgi) |
| `gdi` | Gdi32.dll, the [Windows GDI](https://learn.microsoft.com/en-us/windows/win32/gdi/windows-gdi) |
| **`gui`** | **The WinSafe high-level GUI abstractions** |
| `kernel` | Kernel32.dll, basic kernel functions |
| `mf` | [Media Foundation](https://learn.microsoft.com/en-us/windows/win32/medfound/microsoft-media-foundation-sdk) |
| `ole` | Basic OLE/COM support |
| `oleaut` | [OLE Automation](https://learn.microsoft.com/en-us/windows/win32/api/_automat/) |
| **`raw-dylib`** | **Enables [raw-dylib](https://doc.rust-lang.org/reference/items/external-blocks.html#the-link-attribute) linking** |
| `shell` | Shell32.dll, Shlwapi.dll, and Userenv.dll, the COM-based [Windows Shell](https://learn.microsoft.com/en-us/windows/win32/shell/shell-entry) |
| `taskschd` | [Task Scheduler](https://learn.microsoft.com/en-us/windows/win32/taskschd/task-scheduler-start-page) |
| `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 |

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](https://github.com/rodrigocfd/winsafe-examples)

WinSafe allows you to create windows in two ways:

* programmatically defining parameters; or
* [loading dialogs](https://github.com/rodrigocfd/winsafe-examples/tree/master/03_dialog_resources) from a `.res` file created with a WYSIWYG resource editor.

The [example below](https://github.com/rodrigocfd/winsafe-examples/tree/master/01_button_click/) creates a window  with a button programmatically. Note how the click event is handled with a closure:

![Example 01](https://raw.githubusercontent.com/rodrigocfd/winsafe-examples/master/01_button_click/screen.gif)

```toml
[dependencies]
winsafe = { version = "0.0.22", features = ["gui"] }
```

```rust
#![windows_subsystem = "windows"]

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

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