<!--查看槽点对话框-->
<template lang="html">
 <transition name="el-fade-in-linear">
  <p draggable="true" @drag="mouseDrag" @dragend="mouseDragend" :style="dialogStyle" class="g-dialog-wrapper" v-show="myVisible">
   <p class="g-dialog-header">
    <p class="left">
     模态框
    </p>
    <p class="right">
     <i class="g-times-icon fa fa-times" @click="myVisible=false" aria-hidden="true"></i>
    </p>
   </p>
   <p class="g-dialog-container">
   </p>
  </p>
 </transition>
</template>
<script>
 export default {
  props: {
   visible: Boolean
  },
  created() {

  data() {
   return {
    myVisible: this.visible,
  },
  computed: {},
  methods: {

  components: {},
  watch: {

</script>
<style lang="css" scoped>

<g-key-dialog :visible.sync="keyDialogVisible"></g-key-dialog>
