技术要点

透明背景

src/main/index.ts 的 new BrowserWindow 中添加

    transparent: true, // 设置窗口背景透明frame: false, // 隐藏窗口边框

仅图标和标题部分可拖拽

仅图标和标题部分添加样式 drag

.drag {-webkit-app-region: drag;
}

图标与标题栏的融合

• 标题栏的背景色采用图标的背景色

bg-[#0baaf5]

• 标题栏添加顶部的外边距，值为图标的半径

mt-30px

图标的样式如下：

<img :src="icon" alt="logo" class="fixed h-60px top-[0px] drag" />

窗口置顶

      <Iconv-if="ifTop"icon="stash:pin-thumbtack-solid":class="iconClassString"@click="cancle_top"/><Icon v-else icon="stash:pin-thumbtack" :class="iconClassString" @click="top" />

const ifTop = ref(false)// 窗口置顶
function top() {window.electron.ipcRenderer.send('top')ifTop.value = true
}function cancle_top() {window.electron.ipcRenderer.send('cancle_top')ifTop.value = false
}

src/main/index.ts 中

  ipcMain.on('top', () => {mainWindow.setAlwaysOnTop(true)})ipcMain.on('cancle_top', () => {mainWindow.setAlwaysOnTop(false)})

窗口最小化

 <Icon icon="qlementine-icons:windows-minimize-16" :class="iconClassString" @click="min" />

function min() {window.electron.ipcRenderer.send('min')
}

src/main/index.ts 中

  ipcMain.on('min', () => {mainWindow.minimize()})

窗口最大化 / 取消最大化

      <Iconv-if="ifMax"icon="qlementine-icons:windows-unmaximize-16":class="iconClassString"@click="cancel_max"/><Iconv-elseicon="qlementine-icons:windows-maximize-16":class="iconClassString"@click="max"/>

const ifMax = ref(false)function max() {window.electron.ipcRenderer.send('max')
}function cancel_max() {window.electron.ipcRenderer.send('cancel_max')
}window.electron.ipcRenderer.on('unmaximize', () => {ifMax.value = false
})window.electron.ipcRenderer.on('maximize', () => {ifMax.value = true
})

src/main/index.ts 中

  ipcMain.on('max', () => {mainWindow.maximize()})ipcMain.on('cancel_max', () => {mainWindow.unmaximize()})

因将窗口拖拽到屏幕边缘时，会自动触发最大化，调整窗口大小会退出最大化，则需监听窗口最大化和退出最大化事件，由主进程通知渲染进程状态，以便切换图标。[ 不适应于本范例，因本范例隐藏了 frame ]

  // 窗口变为最大化状态mainWindow.on('maximize', () => {mainWindow.webContents.send('maximize')})// 窗口从最大化状态退出mainWindow.on('unmaximize', () => {mainWindow.webContents.send('unmaximize')})

隐藏窗口到托盘

<Icon icon="si:close-fill" :class="iconClassString" @click="hide" />

function hide() {window.electron.ipcRenderer.send('hide')
}

src/main/index.ts 中

  ipcMain.on('hide', () => {// 使窗口不显示在任务栏中mainWindow.setSkipTaskbar(true)mainWindow.hide()})

代码实现

src/renderer/src/components/TitleBar.vue

<script setup lang="ts">
import icon from '../../../../resources/icon.png'
const props = defineProps({title: {type: String}
})function hide() {window.electron.ipcRenderer.send('hide')
}const ifTop = ref(false)// 窗口置顶
function top() {window.electron.ipcRenderer.send('top')ifTop.value = true
}function cancle_top() {window.electron.ipcRenderer.send('cancle_top')ifTop.value = false
}function min() {window.electron.ipcRenderer.send('min')
}const ifMax = ref(false)function max() {window.electron.ipcRenderer.send('max')
}function cancel_max() {window.electron.ipcRenderer.send('cancel_max')
}window.electron.ipcRenderer.on('unmaximize', () => {ifMax.value = false
})window.electron.ipcRenderer.on('maximize', () => {ifMax.value = true
})const iconClassString = 'cursor-pointer hover:bg-blue-500 block h-full px-2'
</script><template><img :src="icon" alt="logo" class="fixed h-60px top-[0px] drag" /><div class="flex items-center bg-[#0baaf5] text-white h-30px mt-30px"><div class="drag flex-1 pl-70px font-bold text-white">{{ props.title }}</div><div class="flex h-full"><Iconv-if="ifTop"icon="stash:pin-thumbtack-solid":class="iconClassString"@click="cancle_top"/><Icon v-else icon="stash:pin-thumbtack" :class="iconClassString" @click="top" /><Icon icon="qlementine-icons:windows-minimize-16" :class="iconClassString" @click="min" /><Iconv-if="ifMax"icon="qlementine-icons:windows-unmaximize-16":class="iconClassString"@click="cancel_max"/><Iconv-elseicon="qlementine-icons:windows-maximize-16":class="iconClassString"@click="max"/><Icon icon="si:close-fill" :class="iconClassString" @click="hide" /></div></div>
