Electron-disable-minimize NPM

Electron Diable Minimize

This module allow you to set the window attached to the HWND handle to disable minimized.

Electron indeed have a minimizable: false but it minimized at Windows + D (Show Desktop) Event.

This module uses the following c++ code. (Thanks to tordex)

HWND nWinHandle = FindWindowEx(NULL, NULL, "Progman", NULL);
nWinHandle = FindWindowEx(nWinHandle, NULL, "SHELLDLL_DefView", NULL);
SetWindowLongPtr(hwnd, -8, (LONG_PTR)nWinHandle);

Installation

This module only works in windows, but installable mac and linux. (mac and linux nothing's going to happen.)

1. Install Module

npm i -S electron-disable-minimize   # or yarn add electron-disable-minimize

2. Rebuild Package

"./node_modules/.bin/electron-rebuild"  # rebuild native module

or you can rebuild automatically!

// package.json
...
"scripts": {
  "install": "./node_modules/.bin/electron-rebuild"
}
...

npm install # it also run "./node_modules/.bin/electron-rebuild"

Usage

Look at the index.html, index.js and package.json file to integrate it into your Electron application

Basically it consists of 2 steps

Include the module in your .js file:

import { DisableMinimize } from 'electron-disable-minimize';
 - or -
const { DisableMinimize } = require('electron-disable-minimize');

Create your Electron BrowserWindow

const mainWindow = new BrowserWindow({
    height: 800,
    width: 800,
    useContentSize: true,
    transparent: !isDev,
    frame: isDev,
    focusable: isDev,
    show: false
});

mainWindow.loadURL(__dirname + "/index.html");
mainWindow.show();

// get the native HWND handle
const handle = mainWindow.getNativeWindowHandle();

// disable minimize perfectly!
const isSuccess = DisableMinimize(handle);

console.log(isSuccess); // boolean

If false returned, disable minimize failed. (for the same reason as run in other platforms)
