electron制作仿制qq聊天界面的示例代码

本文介绍了electron制作仿制qq聊天界面的示例代码，分享给大家，具体如下：

效果图:

样式使用scss和flex布局

这也是制作im系统的最后一个界面了!

在制作之前参考了qq和千牛

需要注意的点

qq将滚动条美化了 而且在无操作的情况下是不会显示的

滚动条美化

::-webkit-scrollbar { /*滚动条整体样式*/
  width: 5px; /*高宽分别对应横竖滚动条的尺寸*/
  height: 1px;
}

::-webkit-scrollbar-thumb { /*滚动条里面小方块*/
  border-radius: 10px;
  -webkit-box-shadow: inset 0 0 5px rgba(228, 57, 60, 0.2);
  background: rgba(20, 20, 50, 0.6);
  position: absolute;
}

::-webkit-scrollbar-track { /*滚动条里面轨道*/
  -webkit-box-shadow: inset 0 0 5px rgba(228, 57, 60, 0.2);
  border-radius: 10px;
  background: #ededed;
  position: absolute;
}

滚动条根据时机显示

其实这个也很简单 用的mouseenter 和 mouseleave事件

<div
  :style="{overflowy:messagescroll? 'auto' : 'hidden',paddingright: messagescroll ? '0': '5px' }"
  @mouseenter="showmessagescrolls" 
  @mouseleave="hidemessagescrolls">
</div>

# script
 showmessagescrolls(){
   this.messagescroll = true;
},
hidemessagescrolls(){
  this.messagescroll = false;
},

这里解释一下为什么有一个paddingright

因为我们的滚动条是5px 如果不加 在滚动条显示的时候页面会抖动

简单写法

 @mouseenter="messagescroll = true" 
 @mouseleave="messagescroll = false"

页面滚动

页面打开时消息列表滚动到底部

this.$nexttick(function () {
        this.$refs.msgbox.scrolltop = this.$refs.msgbox.scrollheight
})

消息发送滚动到底部

this.$refs.msgbox.scrolltop = this.$refs.msgbox.scrollheight;

内容编辑

没有使用表单元素 直接使用的 contenteditable

因为contenteditable 没法用双向数据绑定 不过 可以用数据侦听器 有很多办法 但是有很简单的 使用input事件就行了

有一个问题就是左侧的列表是没法拉伸的 不过已经做了样式了 如果不想要的可以去掉这个css代码

 &:after {
