如何让我的“查找"对话框不干扰 StyledTextCtrl 中的词法分析器? [英] How do I make my Find dialog not interfere with lexer in StyledTextCtrl?

问题描述

我需要帮助让我的查找对话框不干扰我的词法分析器.我在这个问题中使用了查找对话框，但它使用干扰我的词法分析器的 SetStyles.除了弄乱语法突出显示，当我再次尝试执行 Find 时，它只会突出显示随机的东西.任何帮助表示赞赏！

I need help in making my find dialog not interfere with my lexer. I used the find dialog in this question but it uses SetStyles which interferes with my lexer. Along with messing up the syntax highlighting, when I try to do the Find again, it just highlights random things. Any help is appreciated!

推荐答案

首先，您应该使用词法分析器未使用的样式编号，请参阅 _stc.py 中的样式代码.您还可以使用 Colourise(0, -1) 方法清除自定义样式并将默认词法分析器的颜色重新应用于整个文档(请参阅 StyledTextCtrl 文档).

At first, you should use style number that is not used by lexer, see style codes in _stc.py. You can also use Colourise(0, -1) method to clear your custom styling and reapply default lexer's colorizing to whole document (see StyledTextCtrl documentation).
