我有一个应用程序通过文本小部件显示进度消息，因此如果有很多行，它将滚动。它还会显示一个“任务”。每个步骤的进度条，以及不同的＆＃39; Total＆＃39;完成进度条。
我的情况是，如果他们没有“内容”，我希望不显示进度条。所以他们都没有在处理的开始和结束。 ＆＃39; Total＆＃39;一旦第一步完成，就会显示进度条，并且“任务”将会显示。如果任务足够长，可以显示进度条。
它是一个很棒的应用程序，但这里是我所拥有的缩短版本（但仍然很长）。

当＆＃39;任务＆＃39;进度条显示“进度消息”＆＃39;标签框架是重复的，并向下移动一行（参见屏幕截图）
抱歉，我无法附上截图。这是截图的文字版本！
- 进度讯息---------------------------------------
进度讯息---------------------------------------
消息第1步
[任务进度条]
[总进度条]
显示屏保持这种状态直到结束。即使在“任务”中也是如此。进度条被删除，重复仍然存在。当Total＆＃39; Total＆＃39;总计时，显示屏不会添加第三个版本。显示进度条。
当两个进度条被移除时，一切都会在最后纠正。
所有小部件都网格化到正确的框架，行/列似乎是正确的，所以我在哪里寻找纠正这个。
非常感谢，对不起，这已经很久了。
