[![Build status](https://ci.appveyor.com/api/projects/status/4l1ex72sgca1b3je?svg=true)](https://ci.appveyor.com/project/mmis1000/winctl)

winctl wraps a few functions of the windows api to allow iterating over currently opened windows and performing a few limited operations on them. This is not a production ready module! There is no real documentation either yet. Sorry for that.

The example has to suffice for now.

## Requirements

This module is currently only compatible with Windows. Please ensure you have the [required dependencies](https://github.com/nodejs/node-gyp#installation) as well as Visual Studio installed.

## Building

node-gyp is required to build xinput.js.

Install node-gyp using npm:

```
npm install -g node-gyp
```

Then configure and build:

```
node-gyp configure
node-gyp build
```

## Example

```JavaScript
var winctl = require('../');

var win = winctl.GetActiveWindow();

// Output some information about the currently active window
console.log("Active Window Hwnd:", win.getHwnd());
console.log("Active Window Title:", win.getTitle());
console.log("Dimensions:", win.dimensions());
/* ->
Active Window Hwnd: 26282110
Active Window Title: Bash cpp-modules/winctl
Dimensions: { left: 708, top: 112, right: 2025, bottom: 1132 }
*/

// Manipulate the currently active window a bit
// Move active window to 0,0 and resize it to 800x600
win.move(0, 0, 800, 600);

// Move active window to the right by 30px and increase its width by 60px
win.moveRelative(30, 0, 60, 0);

// Minimize the active window
win.showWindow(winctl.WindowStates.MINIMIZE);

console.log();

// Find a windows "File Explorer" window by ClassName
console.log("Title of window with class 'CabinetWClass':", winctl.GetWindowByClassName("CabinetWClass").getTitle());

// Find a window by exact title
console.log("HWND of window with exact title 'File Explorer':", winctl.GetWindowByTitleExact("File Explorer").getHwnd());

// Find first window containing the string 'alc' and bring it to the foreground
winctl.FindByTitle("alc").then(window => {
	console.log("Title of window with title 'alc':", window.getTitle());
	// --> Title of window with title 'alc': Calculator

	// Activate the window
	window.setForegroundWindow();
});

// Iterate over all windows with a custom filter -> show all visible windows
winctl.FindWindows(win => win.isVisible() && win.getTitle()).then(windows => {
	console.log("Visible windows:");
	windows.sort((a,b) => a.getTitle().localeCompare(b.getTitle())).forEach(window => console.log(" - %s [pid=%d, hwnd=%d, parent=%d]", window.getTitle(), window.getPid(), window.getHwnd(), window.getParent()));
});
/* -->
Visible windows:
 - Bash cpp-modules/winctl [pid=27196, hwnd=26282110, parent=NaN]
 - Bash cpp-modules/winctl [pid=30696, hwnd=10357510, parent=NaN]
 - Calculator [pid=6948, hwnd=5311194, parent=NaN]
 - File Explorer [pid=4860, hwnd=5115324, parent=NaN]
 - src [pid=4860, hwnd=219155192, parent=NaN]
*/


// Log when a new window opens or the active window changes
winctl.Events.addListener("active-window", function(now, prev) {
	console.log("Changed active window to: %s [prev=%s]", now.getTitle(), prev.getTitle());
});

winctl.Events.addListener("open-window", function(win) {
	console.log("Opened new window: %s [%d]", win.getTitle(), win.getHwnd());
});

// Stop listening after 5s
setTimeout(() => {
	winctl.Events.removeAllListeners("active-window");
	winctl.Events.removeAllListeners("open-window");
	console.log("---done---");
}, 5000);
