Flutter桌面软件开发中如何使用bitsdojo_window 自定义拖拽导航以及关闭按钮呢,下面一起看看

一、Flutter桌面软件开发中使用bitsdojo_window 自定义导航需要配置原生代码(可以去掉默认导航)

For Windows apps

Inside your application folder, go to windows\runner\main.cpp and add these two lines at the beginning of the file:

#include <bitsdojo_window_windows/bitsdojo_window_plugin.h>
auto bdw = bitsdojo_window_configure(BDW_CUSTOM_FRAME | BDW_HIDE_ON_STARTUP);
For macOS apps

Inside your application folder, go to macos\runner\MainFlutterWindow.swift and add this line after the one saying import FlutterMacOS :

import FlutterMacOS
import bitsdojo_window_macos // Add this line

Then change this line from:

class MainFlutterWindow: NSWindow {

to this:

class MainFlutterWindow: BitsdojoWindow {

After changing NSWindow to BitsdojoWindow add these lines below the line you changed:

override func bitsdojo_window_configure() -> UInt {
  return BDW_CUSTOM_FRAME | BDW_HIDE_ON_STARTUP
}

Your code should now look like this:

class MainFlutterWindow: BitsdojoWindow {
    
  override func bitsdojo_window_configure() -> UInt {
    return BDW_CUSTOM_FRAME | BDW_HIDE_ON_STARTUP
  }
    
  override func awakeFromNib() {
    ... //rest of your code

如果您不想使用自定义框架而喜欢标准窗口标题栏和按钮,可以从上面的代码中删除BDW_CUSTOM_FRAME

如果您不想在启动时隐藏窗口,则可以从上面的代码中删除BDW_HIDE_ON_STARTUP

二、Flutter桌面软件开发中使用bitsdojo_window 最大化 最小化 关闭 导航拖动组件

1、最小化按钮对应组件
MinimizeWindowButton()

WindowButtonColors

设置按钮的颜色 用在最小化、最大化、关闭按钮上面。可以传入6个参数:

  • Color? normal:普通状态图标背景的颜色
  • Color? mouseOver:鼠标到图标时的背景色
  • Color? mouseDown:鼠标按下按钮时的背景色
  • Color? iconNormal:普通状态下按钮的颜色
  • Color? iconMouseOver:鼠标移动到按钮图标时的图标颜色
  • Color? iconMouseDown:鼠标按下时按钮图标的颜色
 final buttonColors = WindowButtonColors(
  normal: Colors.blue.withOpacity(.2),
  iconNormal: Colors.blue,
  mouseOver: Colors.red,
  mouseDown: Colors.green,
  iconMouseOver: Colors.white,
  iconMouseDown: Colors.orange,
);

 
 MaximizeWindowButton(colors: buttonColors)
2、最大化按钮对应组件

通过appWindow.isMaximized判断是否是最大化,完整代码如下

appWindow.isMaximized
              ? RestoreWindowButton(
                  colors: buttonColors,
                  onPressed: maximizeOrRestore,
                )
              : MaximizeWindowButton(
                  colors: buttonColors,
                  onPressed: maximizeOrRestore,
                ),
)


void maximizeOrRestore() {
  setState(() {
    appWindow.maximizeOrRestore();
  });
}
3、关闭按钮对应组件
CloseWindowButton()
4、设置窗口的边框 WindowBorder
  • required Widget child:桌面程序的主要内容
  • required Color color:边框的颜色
  • double? width:边框的宽度,默认为1

设置窗口的边框。可以传入4个参数:

home: Scaffold(
  body: WindowBorder(
    color: Colors.blue,
    child: const Center(
      child: Text('Hello World'),
    ),
  ),
)
5、顶部拖动按钮组件

WindowTitleBarBox

窗口标题栏。可以传入2个参数:

  • Key? key:🤫
  • Widget? child:标题栏显示的内容

该组件实际上就是一个设置死高度的SizedBox

MoveWindow

可滑动区域。可以传入2个参数:

  • Key? key:🤫
  • Widget? child:移动组件里显示的内容
 WindowTitleBarBox(child: MoveWindow())

三、Flutter桌面软件开发中使用bitsdojo_window 自定义导航和右侧按钮完整代码(官方示例)

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

void main() async {
  runApp(const MyApp());
  doWhenWindowReady(() {
    final win = appWindow;
    const initialSize = Size(600, 450);
    win.minSize = initialSize;
    win.size = initialSize;
    win.alignment = Alignment.center;
    win.title = "Custom window with Flutter";
    win.show();
  });
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: WindowBorder(
      color: const Color(0xFF805306),
      child: Row(
        children: const [LeftSide(), RightSide()],
      ),
    ));
  }
}



//左侧区域
class LeftSide extends StatelessWidget {
  const LeftSide({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return SizedBox(
        width: 100,
        child: Container(
            color: Colors.amber[100],
            child: Column(
              children: [
                //左侧顶部 拖动导航组件
                WindowTitleBarBox(child: MoveWindow()),
                //左侧底部组件
                const Expanded(
                    child: SizedBox(
                  child: const Text("左侧区域"),
                ))
              ],
            )));
  }
}

//右侧区域
class RightSide extends StatelessWidget {
  const RightSide({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Expanded(
      child: SizedBox(
        child: Column(children: [
          //右侧顶部
          Container(
            color: Colors.grey[200],
            child: WindowTitleBarBox(
              child: Row(
                children: [
                  Expanded(child: MoveWindow()),
                  const WindowButtons()
                ],
              ),
            ),
          ),
          //右侧底部
          Expanded(
              child: SizedBox(
            child: ListView.builder(
                itemCount: 50,
                itemBuilder: (context, index) {
                  return ListTile(title: Text("标题-$index"));
                }),
          ))
        ]),
      ),
    );
  }
}

//自定义右侧 最小化 最大化和关闭按钮
class WindowButtons extends StatefulWidget {
  const WindowButtons({Key? key}) : super(key: key);
  @override
  _WindowButtonsState createState() => _WindowButtonsState();
}

class _WindowButtonsState extends State<WindowButtons> {
  final buttonColors = WindowButtonColors(
      iconNormal: Colors.grey[600],
      mouseOver: Colors.grey[400],
      mouseDown: Colors.grey[400],
      iconMouseOver: Colors.grey[600],
      iconMouseDown: Colors.grey[600]);

  void maximizeOrRestore() {
    setState(() {
      appWindow.maximizeOrRestore();
    });
  }

  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        MouseRegion(
          cursor: SystemMouseCursors.click,
          child: MinimizeWindowButton(colors: buttonColors),
        ),
        MouseRegion(
          cursor: SystemMouseCursors.click,
          child: appWindow.isMaximized
              ? RestoreWindowButton(
                  colors: buttonColors,
                  onPressed: maximizeOrRestore,
                )
              : MaximizeWindowButton(
                  colors: buttonColors,
                  onPressed: maximizeOrRestore,
                ),
        ),
        MouseRegion(
          cursor: SystemMouseCursors.click,
          child: CloseWindowButton(colors: buttonColors),
        )
      ],
    );
  }
}
