electron+vue——屏蔽顶部标题栏最大化按钮

js：

import { BrowserWindow } from "electron";

function createWindow() {
  // 创建浏览器窗口
  mainWindow = new BrowserWindow({
    width: 1000,
    height: 600,
    // maximizable: false, //  windows下有效，禁用最大化按钮
    resizable: false, // windows下禁用最大化按钮，linux下隐藏最大化按钮
    ...
  });
}

 

自定义标题栏也可以实现（win/linux兼容），但要考虑窗口大小，不然会出现滚动条

function createWindow() {
  // 创建浏览器窗口
  mainWindow = new BrowserWindow({
    width: 1000,
    height: 630, // 内容高度600+标题栏高度30
    titleBarStyle: "hidden", // 隐藏默认标题栏
    frame: false, // 隐藏边框
    ...
  });
}

App.vue:

<template>
  <div id="app">
    <!-- 自定义标题栏 -->
    <TitleBar
      :app-name="appName"
      @window-control="handleWindowControl"
    ></TitleBar>
    <router-view />
  </div>
</template>

<script>
import TitleBar from "./views/components/titleBar.vue";

export default {
  name: "App",
  components: { TitleBar },
  data() {
    return { appName: "测试标题" };
  },
  methods: {
    // 处理窗口控制
    handleWindowControl(action) {
      switch (action) {
        case "minimize":
          window.desktopHandler.minimizeWindow();
          break;
        case "close":
          window.desktopHandler.confirmClose();
          break;
      }
    },
  },
};
</script>

titleBar.vue:

<template>
  <div class="title-bar">
    <!-- 左侧应用信息 -->
    <div class="left-section">
      <div class="app-info">
        <span class="app-name">{{ appName }}</span>
      </div>
    </div>

    <!-- 右侧窗口控制按钮 -->
    <div class="window-controls">
      <button
        class="control-btn"
        @click="controlWindow('minimize')"
        title="最小化"
      >
        —
      </button>

      <button
        class="control-btn close"
        @click="controlWindow('close')"
        title="关闭"
      >
        X
      </button>
    </div>
  </div>
</template>

<script>
export default {
  props: {
    appName: {
      type: String,
      default: "",
    },
  },
  methods: {
    controlWindow(action) {
      this.$emit("window-control", action);
    },
  },
};
</script>

.title-bar {

  -webkit-app-region: drag;

}

.control-btn.close:hover {

</style>

注意窗口内容需要相对定位：

.container {
  width: 1000px;
  height: 600px;
  position: absolute;
  top: 30px;
}

 preload.js:

import { contextBridge, ipcRenderer } from "electron";

contextBridge.exposeInMainWorld("desktopHandler", {
  confirmClose: () => ipcRenderer.send("confirm-window-close"),
  minimizeWindow: () => ipcRenderer.send("minimize-window"),
});
