c ++多进程写入同一个文件 - 进程间互斥？(c++ multiple processes writing to the same file - Interprocess mutex?)

 你可以像下面的代码那样做。 需要进行一些调整以获得您想要的确切结果（如图像），但我相信它会让您顺利进行。 
 
 我为'进步'栏添加了一些jQuery。 通过使用data-progress （使用百分比!!!），您可以定义进度的程度。 
 
 作为替代方案，您可以将data-progress="90%"更改为style="width: 90%" ，这使其成为100％HTML / CSS。 
 
 
 
 
 
  
$(function() {
	$('.progress>div').each(function() {
  	$(this).css('width', $(this).data('progress') );
  });
});

  box-sizing: border-box;
}

  background: white;
}

  width: 400px;
  margin-bottom: 1em;
}
  .project > div {
    display: inline-block;
    margin: 0 -5px 0 0;
    vertical-align: middle;
  }
.task {
  width: 2em;

  border-radius: 100%;
}
.progress {
  width: calc( 50% - 3em);
  height: .6em;
  padding: .2em 0;
  background: #E4E4E7;
  position: relative;
}
  .progress>div {
    height: .2em;
    left: -.4em;
    right: -.4em;
    position: absolute;
  }
.pending { background: #F8AC59; }
.running { background: #1C84C6; }
.passed { background: #1AB394; }
.failed { background: #ED5565; }

You could do it like the following code. It will need some tweaking to get the exact result you want (like images), but I believe it will get you on your way.
 
I've added a little bit of jQuery for 'progress' bars. By using the data-progress (use percentage!!!) you can define how far the progress is.
 
As an alternative to the you could change the data-progress="90%" to style="width: 90%" which makes it 100% HTML/CSS.
 
 
 
 
 
  
$(function() {
	$('.progress>div').each(function() {
  	$(this).css('width', $(this).data('progress') );
  });
});
