如何在MFC中的CRichEditCtrl中显示红色波浪线 [英] How to display Red Squiggly Lines in CRichEditCtrl in MFC

问题描述

我正在努力在MFC应用程序中实现拼写检查器.我要做的是在拼写错误的单词下显示红线.

I am working on implementing spellchecker in an MFC application. What I want to do is display red lines under incorrectly spelled words.

我找到了一个完成此操作的示例，但它仅适用于简单的编辑框，因为它可以简单地使用编辑控件的默认字体进行计算以绘制波浪线.但是它不适用于丰富的编辑控件，因为在丰富的编辑控件中，不同的单词可能具有不同的字体.在这种情况下，我发现的示例在错误的位置绘制线.

I found one example where it is done but it works only for a simple edit box because it can simply use the edit controls default font for doing calculations to draw the squiggly lines. But it does not work for a rich edit control as in rich edit control it is possible that different words can have different fonts. In this case the example I found draws lines at incorrect places.

请让我知道是否有人已经为CRichEditCtrl完成了此操作? (它必须处理Rich Edit控件中存在的任何字体/大小的文本.)

Please let me know if someone has already done this for CRichEditCtrl? (it must handle text of any font/size that is present in the rich edit control.)

谢谢， 萨钦(Sachin)

Thanks, Sachin

推荐答案

CHARFORMAT2 format;
SecureZeroMemory(&format, sizeof(CHARFORMAT2));
format.cbSize = sizeof(CHARFORMAT2);
format.dwMask = CFM_UNDERLINE|CFM_UNDERLINETYPE;
format.dwEffects = CFE_UNDERLINE;
format.bUnderlineType = CFU_UNDERLINEWAVE | 0x50;
SendMessage(EM_SETCHARFORMAT, SCF_ALL, (LPARAM)&format);

我希望这会在您的文字中加下划线

I hope this will get the underline in your text
