window_manager_plus

window_manager_plus

This plugin allows Flutter desktop apps to create and manage multiple windows, such as resizing and repositioning, and communicate between them.

This is a fork and a re-work of the original window_manager plugin. With inspiration from the desktop_multi_window plugin, this new implementation allows the creation and management of multiple windows.

Linux is not currently supported.

Quick Start

Setup to support multiple windows

macOS

Change the file macos/Runner/MainFlutterWindow.swift as follows:

import Cocoa
import FlutterMacOS
+ import window_manager_plus

class MainFlutterWindow: NSPanel {
    override func awakeFromNib() {
        let flutterViewController = FlutterViewController.init()
        let windowFrame = self.frame
        self.contentViewController = flutterViewController
        self.setFrame(windowFrame, display: true)
        
        RegisterGeneratedPlugins(registry: flutterViewController)
+        
+        WindowManagerPlusPlugin.RegisterGeneratedPlugins = RegisterGeneratedPlugins
        
        super.awakeFromNib()
    }
    
    override public func order(_ place: NSWindow.OrderingMode, relativeTo otherWin: Int) {
        super.order(place, relativeTo: otherWin)
        hiddenWindowAtLaunch()
    }
}

Change the file macos/Runner/AppDelegate.swift as follows:

import Cocoa
import FlutterMacOS
+ import window_manager_plus

@main
class AppDelegate: FlutterAppDelegate {
  override func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
-    return true
+    return NSApp.windows.filter({$0 is MainFlutterWindow || $0 is WindowManagerPlusFlutterWindow}).count == 1 // or return false
  }
}

Without changing the return logic, the application will close when the main flutter window is closed.

Windows

Change the file windows/runner/main.cpp as follows:

#include <flutter/dart_project.h>
#include <flutter/flutter_view_controller.h>
#include <windows.h>

#include "flutter_window.h"
#include "utils.h"

+ #include <iostream>
+ #include "window_manager_plus/window_manager_plus_plugin.h"

int APIENTRY wWinMain(_In_ HINSTANCE instance,
                      _In_opt_ HINSTANCE prev,
                      _In_ wchar_t* command_line,
                      _In_ int show_command) {
  // Attach to console when present (e.g., 'flutter run') or create a
  // new console when running with a debugger.
  if (!::AttachConsole(ATTACH_PARENT_PROCESS) && ::IsDebuggerPresent()) {
    CreateAndAttachConsole();
  }

  // Initialize COM, so that it is available for use in the library and/or
  // plugins.
  ::CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED);

  flutter::DartProject project(L"data");

  std::vector<std::string> command_line_arguments = GetCommandLineArguments();

  project.set_dart_entrypoint_arguments(std::move(command_line_arguments));

  FlutterWindow window(project);
  Win32Window::Point origin(10, 10);
  Win32Window::Size size(1280, 720);
  if (!window.Create(L"window_manager_example", origin, size)) {
    return EXIT_FAILURE;
  }
-  window.SetQuitOnClose(true);
+  window.SetQuitOnClose(false);
+
+  WindowManagerPlusPluginSetWindowCreatedCallback(
+      [](std::vector<std::string> command_line_arguments) {
+        flutter::DartProject project(L"data");
+
+        project.set_dart_entrypoint_arguments(
+            std::move(command_line_arguments));
+
+        auto window = std::make_shared<FlutterWindow>(project);
+        Win32Window::Point origin(10, 10);
+        Win32Window::Size size(1280, 720);
+        // Check whether window->Create or window->CreateAndShow is available.
+        // Take a look at the code above for the main flutter window and 
+        // what method the variable "FlutterWindow window(project)" calls
+        if (!window->Create(L"window_manager_example", origin, size)) {
+          std::cerr << "Failed to create a new window" << std::endl;
+        }
+        window->SetQuitOnClose(false);
+        return std::move(window);
+      });

  ::MSG msg;
  while (::GetMessage(&msg, nullptr, 0, 0)) {
    ::TranslateMessage(&msg);
    ::DispatchMessage(&msg);
  }

  ::CoUninitialize();
  return EXIT_SUCCESS;
}

window->SetQuitOnClose(false); is necessary to prevent the application from closing when the window is closed.

If you want to close the App only when the main window is closed, you can set window->SetQuitOnClose(true); in the main window. The others called inside the WindowManagerPlusPluginSetWindowCreatedCallback should be set to false.

Usage

You must call WindowManagerPlus.ensureInitialized static method and await it before using any WindowManagerPlus methods or WindowManagerPlus.current. It is used to initialize the plugin with the current window ID.

When creating a new window, the args parameter of the main function will have the window ID as a String. You must parse it to an integer and pass it to the WindowManagerPlus.ensureInitialized method. If the args parameter is empty or the first argument is not an integer, then we are in the main window, which ID is exactly 0.

The other arguments will contain the arguments passed to the WindowManagerPlus.createWindow method, if any.

import 'package:flutter/material.dart';
import 'package:window_manager_plus/window_manager_plus.dart';

// Must add List<String> args parameter to your main function.
void main(List<String> args) async {
  WidgetsFlutterBinding.ensureInitialized();
  // await the initialization of the plugin.
  // Here is an example of how to use ensureInitialized in the main function:
  await WindowManagerPlus.ensureInitialized(args.isEmpty ? 0 : int.tryParse(args[0]) ?? 0);
  
  // Now you can use the plugin, such as WindowManagerPlus.current
  WindowOptions windowOptions = WindowOptions(
    size: Size(800, 600),
    center: true,
    backgroundColor: Colors.transparent,
    skipTaskbar: false,
    titleBarStyle: TitleBarStyle.hidden,
  );
  WindowManagerPlus.current.waitUntilReadyToShow(windowOptions, () async {
    await WindowManagerPlus.current.show();
    await WindowManagerPlus.current.focus();
  });

  runApp(MyApp());
}

Create a new window

You can create a new window by calling the WindowManagerPlus.createWindow static method. If you want control the new window, you can use the return value of the method, which returns a WindowManagerPlus instance.

final newWindow = await WindowManagerPlus.createWindow(['my test arg 1', 'my test arg 2']);
if (newWindow != null) {
  print('New Created Window: $newWindow');
}

Communication between windows

You can communicate with another window by using the WindowManagerPlus.invokeMethodToWindow method. The first parameter is the ID of the window you want to communicate with. The second parameter is the method name you want to call. The third parameter is the arguments you want to pass to the method, if any.

The other window must register and implement the WindowListener class and override the WindowListener.onEventFromWindow method to receive the event.

// assuming we are in the first window, Window ID 0, and we want to communicate with the second window.
final secondWindowId = 1; // ID of the second window
final result = await WindowManagerPlus.current.invokeMethodToWindow(secondWindowId, 'myTestMethod', ['arg1', 'arg2']);
// the result will be 'Hello from Window 1'

// assuming we are in the second window, Window ID 1
class _MyWidgetState extends State<MyWidget> with WindowListener {

  // ...

  @override
  void initState() {
    WindowManagerPlus.current.addListener(this);
    super.initState();
  }

  @override
  void dispose() {
    WindowManagerPlus.current.removeListener(this);
    super.dispose();
  }
  
  // ...
  
  @override
  Future<dynamic> onEventFromWindow(String eventName, int fromWindowId, dynamic arguments) async {
    print('[${WindowManagerPlus.current}] Event $eventName from Window $fromWindowId with arguments $arguments');
    return 'Hello from ${WindowManagerPlus.current}';
  }
}

Using WindowManagerPlus.getAllWindowManagerIds() static method you can get all the window manager ids available.

Please see the example app of this plugin for a full example.

Listening events

The WindowListener mixin class is used to listen to window events. If this is used as a Global Listener using the WindowManagerPlus.addGlobalListener static method, the windowId parameter will be the ID of the window that emitted the event, otherwise, it will be always null.

import 'package:flutter/cupertino.dart';
import 'package:window_manager_plus/window_manager_plus.dart';

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> with WindowListener {
  @override
  void initState() {
    super.initState();
    WindowManagerPlus.current.addListener(this);
  }

  @override
  void dispose() {
    WindowManagerPlus.current.removeListener(this);
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    // ...
  }

  @override
  void onWindowEvent(String eventName, [int? windowId]) {
    print('[WindowManager] onWindowEvent: $eventName');
  }

  @override
  void onWindowClose([int? windowId]) {
    // do something
  }

  @override
  void onWindowFocus([int? windowId]) {
    // do something
  }

  @override
  void onWindowBlur([int? windowId]) {
    // do something
  }

  @override
  void onWindowMaximize([int? windowId]) {
    // do something
  }

  @override
  void onWindowUnmaximize([int? windowId]) {
    // do something
  }

  @override
  void onWindowMinimize([int? windowId]) {
    // do something
  }

  @override
  void onWindowRestore([int? windowId]) {
    // do something
  }

  @override
  void onWindowResize([int? windowId]) {
    // do something
  }

  @override
  void onWindowMove([int? windowId]) {
    // do something
  }

  @override
  void onWindowEnterFullScreen([int? windowId]) {
    // do something
  }

  @override
  void onWindowLeaveFullScreen([int? windowId]) {
    // do something
  }
}
