Python 如何在QSCINTILA编辑器中查找单词并转到行？

我想创建一个用于搜索单词并在QSCINTILA编辑器中突出显示它们的函数，以及另一个用于转到编辑器中特定行的函数

我知道这些函数在QPlainTextEdit是有用的，但是自从我学习Qscintilla，而且大部分的文件都是用C++编写的，我很难理解，Scintilla的方法也有很大的不同。

我不知道如何实现这两个功能，我一直在尝试，但没有找到这个词的积极结果。但是，对于第二个函数，我可以打印以行号开头的单词，但我想在搜索函数“转到行”时用行号突出显示该单词。

@ekhumaro感谢您的提示。我试图使用它，但没有成功。我无法理解如何实现该功能。我试着这样做：word=self.dock.findLine.text（）self.textEdit.findFirst（word），其中textEdit指的是qscisintilla。我还尝试了self.textdedit.findFirst（word，qscisintilla.SCFIND_WHOLEWORD），但没有成功。你能写下函数或给我一个例子吗。非常感谢。你为什么不看看我链接的文档呢？它非常清楚地解释了所有论点的作用。@Ekhumaro谢谢你的提示。我试图使用它，但没有成功。我无法理解如何实现该功能。我试着这样做：word=self.dock.findLine.text（）self.textEdit.findFirst（word），其中textEdit指的是qscisintilla。我还尝试了self.textdedit.findFirst（word，qscisintilla.SCFIND_WHOLEWORD），但没有成功。你能写下函数或给我一个例子吗。非常感谢。你为什么不看看我链接的文档呢？它非常清楚地解释了所有论点的作用。
