electron制作仿制qq聊天界面的示例代码
更新：HHH 时间：2023-1-7

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
  :
  @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 {
   display: inline-block;
   content: '';
   width: 5px;
