vue二次封装ant-design-vue中的Modal弹窗组件，实现拖拽，全屏两种功能，原有参数属性不变

<template>
  <a-modal
    :width="width"
    :title="title"
    :visible="visible"
    :confirmLoading="confirmLoading"
    :footer="null"
    :destroyOnClose="true"
    @cancel="handleCancel"
    :draggable="true"
    :maskClosable="false"
  >
    <!-- 自定义内容 -->
    <slot></slot>
    <!-- 工具栏 -->
    <div class="modal-toolbar">
      <a-icon type="fullscreen" @click="handleFullScreen" />
      <a-icon type="close" @click="handleCancel" />
    </div>
  </a-modal>
</template>
 
<script>
import Vue from 'vue';
import { Modal as AntModal, Icon as AntIcon } from 'ant-design-vue';
 
Vue.use(AntModal);
Vue.use(AntIcon);
 
export default {
  name: 'DraggableModal',
  props: {
    width: {
      type: Number,
      default: 520
    },
    title: {
      type: String,
      default: ''
    },
    visible: {
      type: Boolean,
      default: false
    },
    confirmLoading: {
      type: Boolean,
      default: false
    }
  },
  methods: {
    handleCancel() {
      this.$emit('update:visible', false);
    },
    handleFullScreen() {
      // 实现全屏逻辑
    }
  }
};
</script>
 
<style scoped>
.modal-toolbar {
  position: absolute;
  right: 10px;
  top: 10px;
  z-index: 10;
}
.modal-toolbar .ant-icon {
  cursor: pointer;
  margin-left: 10px;
}
</style>

这个代码示例展示了如何创建一个可以拖拽和全屏的Ant Design Vue模态框组件。组件接受标准的a-modal属性，并添加了draggable和handleFullScreen方法来实现这两个额外的功能。注意，实现全屏功能需要额外的逻辑来处理样式和位置的变化。
