Windows window manipulation for node.js
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.
This module is currently only compatible with Windows. Please ensure you have the required dependencies as well as Visual Studio installed.
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
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()));
});

// Log when a new window opens or the active window changes
