我正在编写一个脚本，可以搜索配方及其成分的列表。我想要一个类似google搜索框的东西，在键入时会给出一个下拉列表（这样用户可以看到成分并且没有错字）。我为此使用了组合框，但是我需要支持多种成分搜索，并且从组合框中进行选择会覆盖整个框（而不是部分框）。从组合框中选择时，我也无法键入。我可以使用任何命令来解决这些问题，还是必须覆盖脚本中的某些默认方法？如果是这样，请告诉我该怎么做。
我谦虚地接受我的代码的任何建议或批评。
感谢您抽出宝贵的时间阅读我的代码，并帮助我提出解决方案。
'__init__'包括窗口的所有内容，update_combo用于更新组合框的值，searchall和searchavailability只是该应用程序的功能，与上述问题无关。 count_drinks与上面的问题也不相关。
