引言

在现代Web开发中，模仿桌面应用程序的界面已经成为一种常见的需求。通过使用Vue3，我们可以轻松地创建一个模仿Windows窗口的Web应用程序。本文将详细介绍如何利用Vue3实现这一目标，涵盖从项目初始化到窗口管理的各个方面。

项目初始化

首先，我们需要创建一个新的Vue3项目。可以使用Vue CLI来快速搭建项目结构。

vue create vue3-windows

在项目创建过程中，选择Vue3作为项目的框架。创建完成后，进入项目目录并启动开发服务器。

cd vue3-windows
npm run serve

创建窗口组件

接下来，我们需要创建一个窗口组件。在src/components目录下创建一个新的文件Window.vue。

<template>
  <div class="window">
    <div class="title-bar">
      <span class="title">{{ title }}</span>
      <div class="controls">
        <button @click="minimize">-</button>
        <button @click="maximize">□</button>
        <button @click="close">×</button>
      </div>
    </div>
    <div class="content">
      <slot></slot>
    </div>
  </div>
</template>

<script>
export default {
  props: {
    title: {
      type: String,
      default: 'Window'
    }
  },
  methods: {
    minimize() {
      this.$emit('minimize');
    },
    maximize() {
      this.$emit('maximize');
    },
    close() {
      this.$emit('close');
    }
  }
};
</script>

<style scoped>
.window {
  width: 400px;
  height: 300px;
  border: 1px solid #ccc;
  border-radius: 5px;
  overflow: hidden;
  display: flex;
  flex-direction: column;
}

.title-bar {
  background-color: #f0f0f0;
  padding: 5px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  border-bottom: 1px solid #ccc;
}

.title {
  font-weight: bold;
}

.controls button {
  background: none;
  border: none;
  cursor: pointer;
  margin-left: 5px;
}

.content {
  flex: 1;
  padding: 10px;
  overflow: auto;
}
</style>

这个窗口组件包含一个标题栏和一个内容区域。标题栏中显示了窗口的标题，并提供了最小化、最大化和关闭按钮。

窗口拖拽功能

为了实现窗口的拖拽功能，我们需要监听鼠标事件并更新窗口的位置。

<template>
  <div class="window" :style="windowStyle" @mousedown="startDrag">
    <div class="title-bar">
      <span class="title">{{ title }}</span>
      <div class="controls">
        <button @click="minimize">-</button>
        <button @click="maximize">□</button>
        <button @click="close">×</button>
      </div>
    </div>
    <div class="content">
      <slot></slot>
    </div>
  </div>
</template>

<script>
export default {
  props: {
    title: {
      type: String,
      default: 'Window'
    }
  },
  data() {
    return {
      isDragging: false,
      startX: 0,
      startY: 0,
      offsetX: 0,
      offsetY: 0
    };
  },
  computed: {
    windowStyle() {
      return {
        position: 'absolute',
        left: `${this.offsetX}px`,
        top: `${this.offsetY}px`
      };
    }
  },
  methods: {
    startDrag(event) {
      this.isDragging = true;
      this.startX = event.clientX;
      this.startY = event.clientY;
      window.addEventListener('mousemove', this.onDrag);
      window.addEventListener('mouseup', this.stopDrag);
    },
    onDrag(event) {
      if (this.isDragging) {
        this.offsetX += event.clientX - this.startX;
        this.offsetY += event.clientY - this.startY;
        this.startX = event.clientX;
        this.startY = event.clientY;
      }
    },
    stopDrag() {
      this.isDragging = false;
      window.removeEventListener('mousemove', this.onDrag);
      window.removeEventListener('mouseup', this.stopDrag);
    },
    minimize() {
      this.$emit('minimize');
    },
    maximize() {
      this.$emit('maximize');
    },
    close() {
      this.$emit('close');
    }
  }
};
</script>

<style scoped>
.window {
  width: 400px;
  height: 300px;
  border: 1px solid #ccc;
  border-radius: 5px;
  overflow: hidden;
  display: flex;
  flex-direction: column;
  user-select: none;
}

.title-bar {
  background-color: #f0f0f0;
  padding: 5px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  border-bottom: 1px solid #ccc;
  cursor: move;
}

.title {
  font-weight: bold;
}

.controls button {
  background: none;
  border: none;
  cursor: pointer;
  margin-left: 5px;
}

.content {
  flex: 1;
  padding: 10px;
  overflow: auto;
}
</style>

在这个版本中，我们添加了startDrag、onDrag和stopDrag方法来处理窗口的拖拽逻辑。通过监听mousedown、mousemove和mouseup事件，我们可以实现窗口的拖拽功能。

窗口缩放功能

为了实现窗口的缩放功能，我们需要在窗口的右下角添加一个可拖拽的缩放手柄，并监听鼠标事件来调整窗口的大小。

<template>
  <div class="window" :style="windowStyle" @mousedown="startDrag">
    <div class="title-bar">
      <span class="title">{{ title }}</span>
      <div class="controls">
        <button @click="minimize">-</button>
        <button @click="maximize">□</button>
        <button @click="close">×</button>
      </div>
    </div>
    <div class="content">
      <slot></slot>
    </div>
    <div class="resize-handle" @mousedown="startResize"></div>
  </div>
</template>

<script>
export default {
  props: {
    title: {
      type: String,
      default: 'Window'
    }
  },
  data() {
    return {
      isDragging: false,
      isResizing: false,
      startX: 0,
      startY: 0,
      offsetX: 0,
      offsetY: 0,
      width: 400,
      height: 300
    };
  },
  computed: {
    windowStyle() {
      return {
        position: 'absolute',
        left: `${this.offsetX}px`,
        top: `${this.offsetY}px`,
        width: `${this.width}px`,
        height: `${this.height}px`
      };
    }
  },
  methods: {
    startDrag(event) {
      this.isDragging = true;
      this.startX = event.clientX;
      this.startY = event.clientY;
      window.addEventListener('mousemove', this.onDrag);
      window.addEventListener('mouseup', this.stopDrag);
    },
    onDrag(event) {
      if (this.isDragging) {
        this.offsetX += event.clientX - this.startX;
        this.offsetY += event.clientY - this.startY;
        this.startX = event.clientX;
        this.startY = event.clientY;
      }
    },
    stopDrag() {
      this.isDragging = false;
      window.removeEventListener('mousemove', this.onDrag);
      window.removeEventListener('mouseup', this.stopDrag);
    },
    startResize(event) {
      this.isResizing = true;
      this.startX = event.clientX;
      this.startY = event.clientY;
      window.addEventListener('mousemove', this.onResize);
      window.addEventListener('mouseup', this.stopResize);
    },
    onResize(event) {
      if (this.isResizing) {
        this.width += event.clientX - this.startX;
        this.height += event.clientY - this.startY;
        this.startX = event.clientX;
        this.startY = event.clientY;
      }
    },
    stopResize() {
      this.isResizing = false;
      window.removeEventListener('mousemove', this.onResize);
      window.removeEventListener('mouseup', this.stopResize);
    },
    minimize() {
      this.$emit('minimize');
    },
    maximize() {
      this.$emit('maximize');
    },
    close() {
      this.$emit('close');
    }
  }
};
</script>

<style scoped>
.window {
  position: absolute;
  border: 1px solid #ccc;
  border-radius: 5px;
  overflow: hidden;
  display: flex;
  flex-direction: column;
  user-select: none;
}

.title-bar {
  background-color: #f0f0f0;
  padding: 5px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  border-bottom: 1px solid #ccc;
  cursor: move;
}

.title {
  font-weight: bold;
}

.controls button {
  background: none;
  border: none;
  cursor: pointer;
  margin-left: 5px;
}

.content {
  flex: 1;
  padding: 10px;
  overflow: auto;
}

.resize-handle {
  position: absolute;
  right: 0;
  bottom: 0;
  width: 10px;
  height: 10px;
  background-color: #ccc;
  cursor: se-resize;
}
</style>

在这个版本中，我们添加了一个resize-handle元素，并实现了startResize、onResize和stopResize方法来处理窗口的缩放逻辑。通过监听mousedown、mousemove和mouseup事件，我们可以实现窗口的缩放功能。

窗口最小化、最大化和关闭功能

为了实现窗口的最小化、最大化和关闭功能，我们需要在窗口组件中添加相应的事件处理逻辑。

<template>
  <div class="window" :style="windowStyle" @mousedown="startDrag">
    <div class="title-bar">
      <span class="title">{{ title }}</span>
      <div class="controls">
        <button @click="minimize">-</button>
        <button @click="maximize">□</button>
        <button @click="close">×</button>
      </div>
    </div>
    <div class="content">
      <slot></slot>
    </div>
    <div class="resize-handle" @mousedown="startResize"></div>
  </div>
</template>

<script>
export default {
  props: {
    title: {
      type: String,
      default: 'Window'
    }
  },
  data() {
    return {
      isDragging: false,
      isResizing: false,
      startX: 0,
      startY: 0,
      offsetX: 0,
      offsetY: 0,
      width: 400,
      height: 300,
      isMinimized: false,
      isMaximized: false
    };
  },
  computed: {
    windowStyle() {
      if (this.isMinimized) {
        return {
          display: 'none'
        };
      }
      if (this.isMaximized) {
        return {
          position: 'absolute',
          left: '0',
          top: '0',
          width: '100%',
          height: '100%'
        };
      }
      return {
        position: 'absolute',
        left: `${this.offsetX}px`,
        top: `${this.offsetY}px`,
        width: `${this.width}px`,
        height: `${this.height}px`
      };
    }
  },
  methods: {
    startDrag(event) {
      this.isDragging = true;
      this.startX = event.clientX;
      this.startY = event.clientY;
      window.addEventListener('mousemove', this.onDrag);
      window.addEventListener('mouseup', this.stopDrag);
    },
    onDrag(event) {
      if (this.isDragging) {
        this.offsetX += event.clientX - this.startX;
        this.offsetY += event.clientY - this.startY;
        this.startX = event.clientX;
        this.startY = event.clientY;
      }
    },
    stopDrag() {
      this.isDragging = false;
      window.removeEventListener('mousemove', this.onDrag);
      window.removeEventListener('mouseup', this.stopDrag);
    },
    startResize(event) {
      this.isResizing = true;
      this.startX = event.clientX;
      this.startY = event.clientY;
      window.addEventListener('mousemove', this.onResize);
      window.addEventListener('mouseup', this.stopResize);
    },
    onResize(event) {
      if (this.isResizing) {
        this.width += event.clientX - this.startX;
        this.height += event.clientY - this.startY;
        this.startX = event.clientX;
        this.startY = event.clientY;
      }
    },
    stopResize() {
      this.isResizing = false;
      window.removeEventListener('mousemove', this.onResize);
      window.removeEventListener('mouseup', this.stopResize);
    },
    minimize() {
      this.isMinimized = true;
      this.$emit('minimize');
    },
    maximize() {
      this.isMaximized = !this.isMaximized;
      this.$emit('maximize');
    },
    close() {
      this.$emit('close');
    }
  }
};
</script>
