Python win32 api drawText() 和 SetTextColor
Python win32 api drawText() and SetTextColor
我设法拼凑了一个程序，该程序在多行上接收字符串并将它们打印到透明背景上。我想知道是否有办法为字符串的各个部分涂上不同的颜色。我知道有，但我对 win32 的不了解确实妨碍了我的工作。我需要将文本分成两部分并调用 drawText() 还是可以在字符串中途更改文本颜色？任何关于信息或解决方案的观点都会很棒。
示例：字符串 = "Username: some message that the user has sent."
我已经在 Stack 和其他多个网站上进行了搜索，但到目前为止还没有找到满意的结果。

是的，在调用DrawText
之前必须使用SetTextColor来改变颜色
您使用 DT_CALCRECT 选项调用 DrawText 是正确的。这不会绘制任何东西，它只是计算矩形的高度（基于宽度...）Python 的 DrawText 将 return 计算矩形的元组。
然后再次调用 DrawText，使用相同的文本格式，但没有 DT_CALCRECT 标志。然后偏移矩形，改变颜色，绘制下一个文本。
注意，这在 pywin32 中会变得非常混乱，首先在 C/C++ 中尝试可能更容易。
